Arch Linux Progress information

I have a Arch Linux Todo, this is mostly things that I must not forget to do later on. Things that I have read in the ArchWiki but what I do not have time for yet.

Arch Linux (re-)installation Count: 4

Initial Setup

  • 05/02/2026 09:15-11:30
  • 05/02/2026 12:30-16:15
  • Total: 6h

I installed the torrent version, and then installed sudo apt install qbittorrent to be able to download the full file from the torrent. After torrenting the entire file, I checked the .iso it’s checksum:

echo "c0ee0dab0a181c1d6e3d290a81ae9bc41c329ecaa00816ca7d62a685aeb8d972  /home/<my_username>/Downloads/archlinux-2026.02.01-x86_64.iso" | sha256sum -c -

And it returned: /home/<my_username>/Downloads/archlinux-2026.02.01-x86_64.iso: OK which means it is good. Make sure to use the current checksum from the download page.

I am going to install it with a USB flash drive.

After installing the flashdrive, I have to point my pc to it in the BIOS and select Arch Linux Install Medium

Installing the flash drive

I first made sure that it is not mounted. then I ran

sudo dd bs=4M if=/home/<my_username>/Downloads/archlinux-2026.02.01-x86_64.iso \
  of=/dev/disk/by-id/usb-Generic_Flash_Disk_ABC00630-0:0 conv=fsync oflag=direct status=progress

When booted in terminal

After you told the BIOS to boot Arch Linux, you will be met with a terminal.

localectl list-keymaps
loadkeys us
setfont lat2-16 -m 8859-2

cat /sys/firmware/efi/fw_platform_size

With this we can see our Boot mode. If it is 64, it means it is UEFI booted in 64 bit.

Connect to internet

Then we try and connect to the internet with

ip link

To verify that you connected to it, you can ping:

ping ping.archlinux.org

Sync the clock

timedatectl

Mounting and formatting

wipefs -a /dev/nvme0n1
parted /dev/nvme0n1 mklabel gpt
parted /dev/nvme0n1

And then in the parted, these commands:

mkpart EFI fat32 1MiB 1025MiB
set 1 esp on
mkpart SWAP linux-swap 1025MiB 5121MiB
mkpart ROOT ext4 5121MiB 100%
quit

mkfs.fat -F32 /dev/nvme0n1p1
mkswap /dev/nvme0n1p2
mkfs.ext4 /dev/nvme0n1p3

then I ran:

blkid /dev/nvme0n1p1 /dev/nvme0n1p2 /dev/nvme0n1p3

And nano /etc/fstab:

# /etc/fstab: static file system information.
# See man fstab(5)

# EFI System Partition
UUID=AA11-BB22   /boot     vfat    defaults,noatime   0 2

# Swap
UUID=11112222-3333-4444-5555-666677778888   none    swap    sw   0 0

# Root filesystem
UUID=99998888-7777-6666-5555-444433332222   /   ext4   defaults,noatime   0 1

Where the UUID’s are replaced with the ones the blkid command showed.

and then I ran mount -a to test it.

pacstrap -K /mnt base linux linux-firmware amd-ucode networkmanager nano vim man-db man-pages

Configuring

genfstab -U /mnt >> /mnt/etc/fstab
arch-chroot /mnt
ln -sf /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
hwclock --systohc
locale-gen

Then I created a /etc/locale.conf with LANG=en_US.UTF-8. I also created /etc/hostname with mothership as text. and i created /etc/vconsole.conf with the same keyboard as before: KEYMAP=us

Then I set a root password:

passwd

Then I skipped setting up a bootloader since I already have grub for my ubuntu, so I loaded my ubuntu and ran:

sudo update-grub

grub-install —target=x86_64-efi —efi-directory=/boot/efi —bootloader-id=Arch grub-mkconfig -o /boot/grub/grub.cfg


and then this on my ubuntu to keep using the grub on ubuntu's side:

sudo os-prober sudo update-grub

Fixing more bugs

  • 18/02/2026 13:00-13:45
  • Total: 6.45h

When I relaunched my Arch Linux partition, I got this:

[FAILDED] Failed to mount run-rpc_pipefs.mount - RPC Pipe File System. See 'systemctl status run-rpc_pipefs.mount' for details

And my first approach was to just immediately reboot. That didn’t fix it. When I ran systemctl status run-rpc_pipefs.mount I got this:

âś• run-rpc_pipes.mount - RPC Pipe File System
Loaded: loaded (/run/systemd/generator/run-rpc_pipes.mount; generated)

Feb 18 13:09:04 oldmartiintje-MS-7E26 systemd[1]: Failed to mount run-rpc_pipes.mount - RPC Pipe File System.

Claude Haiku 4.5 has assessed that the issue is because my Arch install includes NFS client by default via networkmanager and base packages. The system tries to mount the RPC pipes filesystem, but the sunrpc kernel module either isn’t loaded or configured properly. This is harmless but noisy.

It suggests 2 paths:

  • disabling NFS
  • Loading the kernel module to fix it.

The Arch wiki tells me that NFS is a distributed file system protocol, allowing a user on a client computer to access files over a network in a manner similar to how local storage is accessed. Seeing as I might use this in the future, I will go with the fix route instead of avoidance.

I tried running sudo modprobe sunrpc but that gave me a FATAL: module sunrpc not found in directory /lib/modules/6.18.7-arch1-1. This points me towards the fact that sunrpc doesn’t exist and didn’t come bundled with my install. I could re-bundle the kernel headers. but i’ll just choose the disable route for now. I’ll just write it down in my Desktop Arch Installation Context note.

sudo systemctl mask run-rpc_pipes.mount
sudo systemctl mask rpc-gssd.service

And it got this response:

Unit run-rpc_pipes.mount does not exist, proceeding anyway. Created symlink /etc/systemd/system/run-rpc_pipes.mount → /dev/null.

Created symlink /etc/systemd/system/rpc-gssd.service → /dev/null.

and then I ran systemctl reboot to check if it has been fixed.

Now when I select my Arch Linux in my grub, it first displays the text of, initialized A, initialized B etc etc. and then it sends me to my Ubuntu login screen?? I wanna cry SKULLEMOJI

Post-Installation

  • 18/02/2026 14:00-14:15
  • 19/02/2026 11:45-12:00
  • Total: 7.15h

The issue is as described above: Now when I select my Arch Linux in my grub, it first displays the text of, initialized A, initialized B etc etc. and then it sends me to my Ubuntu login screen.

First off I am going to run sudo update-grub again on my Ubuntu. And that has fixed the issue :D

See General recommendations for system management directions and post-installation tutorials (like creating unprivileged user accounts, setting up a graphical user interface, sound or a touchpad).

For a list of applications that may be of interest, see List of applications.

This was at the end of the arch wiki installation guide. And we’ll be going to do the general recommendations now.

A new installation leaves you with only the superuser account, better known as “root”. Logging in as root for prolonged periods of time, possibly even exposing it via SSH on a server, is insecure.

So now we are going to create an unprivileged account. We are going to do so by first reading about users and groups: Arch wiki.

useradd -m pye
passwd pye

This has added my main user to the pc.

Security

  • 19/02/2026 11:45-13:30
  • Total: 9h

I am going to be hardening my system according to the Arch Wiki. This page goes deeply into securing your passwords. Principles on how to backup your passwords, etc etc. It also explains how hashing works, it mentions salted passwords and rainbow tables.

I ran grep -r . /sys/devices/system/cpu/vulnerabilities/ to see if there were any known vulnerabilities on my CPU, all entries are either Not affected or it is already mitigated.

Data-at-rest encryption, preferably full-disk encryption with a strong passphrase, is the only way to guard data against physical recovery. This provides data confidentiality when the computer is turned off or the disks in question are unmounted. But I do not need this on my desktop, so for now I’ll skip this.

The default umask 0022 can be changed to improve security for newly created files. The NSA RHEL5 Security Guide suggests a umask of 0077 for maximum security, which makes new files not readable by users other than the owner. So I switched to our user to see our umask value:

su pye
umask
exit

This returned a 0022

So I ran nano /etc/login.defs and changed the umask from 022 to 077. This means it has been set globally :3

Enforce delay on failed login attempts: Add the following line to /etc/pam.d/system-login to add a delay of at least 4 seconds between failed login attempts, ofc with an editor like nano:

auth optional pam_faildelay.so delay=4000000

4000000 is the time in microseconds to delay.

I have learned that sudo is better than su because apparently:

  • sudo keeps a log of commands executed.
  • it prevents you from auto running things as root since your terminal stays normal. Only the commands where you add sudo will be privileged.

Denying root via SSH Even if you do not wish to deny root login for local users, it is always good practice to deny root login via SSH. The purpose of this is to add an additional layer of security before a user can completely compromise your system remotely. SSH can be configured to deny remote logins with the root user by editing the “Authentication” section in the daemon configuration file. Simply set PermitRootLogin to no:

nano /etc/ssh/sshd_config.d/20-deny_root.conf

and set it to be like:

PermitRootLogin no

And then restart the SSH daemon or just, wait till you restart your pc and don’t use SSH in the meanwhile.

I know that it can be smart to disable emergency shell, but I am not risking breaking my system and not being able to recover it. So I am taking the attack risk.

And with this, we finally left the security section of the ArchWiki. We will come back to it via the Arch Linux Todo, but for now, we are able to continue.

System Maintenance

  • 19/02/2026 15:45-16:45
  • Total: 10h

Arch Linux is a rolling release system and has rapid package turnover, so users have to take some time to do system maintenance.

Running systemctl --failed gave me 0 errors.

I ran journalctl -b, it gave me this error when scrolling through:

RDSEED32 is broken. Disabling the corresponding CPUID bit.

I have opened this new article for it: RDSEED32 is broken - Disabling the corresponding CPUID bit.

Before upgrading, users are expected to visit the Arch Linux home page to check the latest news, or alternatively subscribe to the RSS feed or the arch-announce mailing list. When updates require out-of-the-ordinary user intervention (more than what can be handled simply by following the instructions given by pacman), an appropriate news post will be made.

Before upgrading fundamental software (such as the kernel, xorg, systemd, or glibc) to a new version, look over the appropriate forum to see if there have been any reported problems.

Users must equally be aware that upgrading packages can raise unexpected problems that could need immediate intervention; therefore, it is discouraged to upgrade a stable system shortly before it is required for carrying out an important task. Instead, wait to upgrade until there is enough time available to resolve any post-upgrade issues.

Tip

You could use a pacman hook like informant, newscheck or arch-manwarn which prevents you from updating if there is fresh Arch News that you have not read since the last update ran.

When upgrading the system, be sure to pay attention to the alert notices provided by pacman. If any additional actions are required by the user, be sure to take care of them right away. If a pacman alert is confusing, search the forums or check the latest news on the Arch Linux homepage (see Read before upgrading the system) for more detailed instructions.

Installing software Pacman does a much better job than you at keeping track of files. If you install things manually you will, sooner or later, forget what you did, forget where you installed to, install conflicting software, install to the wrong locations, etc.

PACMAN pacman is the Arch Linux package manager: it is highly encouraged to become familiar with it before reading any other articles. Ofc I have my own article: pacman.

Graphical User Interface

  • 16/03/2026 15:30-18:15
  • Total: 13h

There is this list of things related to the GUI.

This is the point where I’ll have to choose a desktop environment:

  • KDE
  • GNOME
  • COSMIC
  • Xfce
  • Cinnamon
  • LXDE

I have chosen KDE. This means I’ll have to follow the KDE guide.

after fixing the user doesn’t have sudo access issue, i was able to run pacman -S plasma-meta as pye. I couldve also just installed it from root user. but I haven’t been using root for a bit

Running pacman -S plasma-meta gave me a lot of 404 issues. so i did:

sudo pacman -S archlinux-keyring
sudo pacman -Sy

And then I retried sudo pacman -S plasma-meta and it fixed the issue I had, but gave me another issue. Some packages already existed, so I tried:

sudo pacman -Syu gcc-libs
sudo pacman -S plasma-meta

And this finally allowed me to install it.

user doesn’t have sudo access

I am using pye ever since I created the user, so it could easily be fixed by logging into root user, but i don’t want to.

pye didn’t have access to run sudo. so i did the following when logged in as root:

su
pacman -S sudo
usermod -aG wheel pye

and then edit /etc/sudoers so that this is not commented out %wheel ALL=(ALL:ALL) ALL

and then i logged out and into pye: logout

nvidia and stuff

If you are an NVIDIA user, ensure the DRM kernel mode setting is enabled. is what the KDE page on the ArchWiki says.

Which gives me the command cat /sys/module/nvidia_drm/parameters/modeset on the nvidia page. But for this I first need to install nvidia drivers.

lspci -k -d ::03xx

This command gives you information about your nvidia GPU, and on this website you’ll be able to find the codenames.

Make sure to pick the right drivers as told on the nvidia page on the ArchWiki. I ran this since this is the right one for my system:

sudo pacman -S nvidia-open

Then to avoid some issues:

sudo nano /etc/pacman.conf

and made sure Include = /etc/pacman.conf.d/mirrorlist wasn’t commented out ([multilib])

sudo pacman -Sy
sudo mkinitcpio -P

I tried running the optional sudo pacman -S lib32-nvidia-utils since I’d need it in the future for steam (I thought I had read). but it failed. So I have skipped it for now.

it is time for a sudo reboot.

And I got yet again booted into ubuntu instead of Arch Linux, when I selected Arch in the grub menu. I think this is an issue to do with the reboot vs the shutdown + startup, cause the latter works normally.

cat /sys/module/nvidia_drm/parameters/modeset

this command now finally returns something: Y

Starting plasma

/usr/lib/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland

Touchdown, we have a GUI.

now, let’s make it load on startup.

mkdir -p ~/.config/systemd/user
nano ~/.config/systemd/user/plasmawayland.service

And then add this:

[Unit]
Description=Start KDE Plasma on Wayland
After=graphical-session-pre.target
PartOf=graphical-session.target

[Service]
Type=simple
ExecStart=/usr/lib/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland
Restart=on-failure

[Install]
WantedBy=graphical-session.target

and then:

systemctl --user daemon-reload
systemctl --user enable plasmawayland.service
sudo reboot

and that gave me a startup issue :/

RESET

21/03/2026 I had to reset the disk since I needed Windows for my D-Link DWM-222 SIM Adapter uitzoeken. This could be done without deleting the Arch disk, but I thought, it already is cursed. Why don’t I reset my disk, add Windows, and add Arch besides it with Archinstall, cause I wanted to learn that anyways.

Restarting from scratch

  • 18/04/2026 09:15-12:45
  • Total: 16.5h

I am going to restart all over again. But this time I have set the Default drive to the drive that my Arch Linux is on to hopefully fix the issues I had last time and to let Arch control grub.

I probably still will need to deactivate grub on my Ubuntu afterwards.

I also skipped wiping the system because I now have a 100GB windows partition on the same drive. And I suspect everything will go smoother now since I now can see which drive (nvme0n1 or nvme1n1) since I can now see the difference between a 100GB partition and a 900GB partition. Which I think I have chosen wrong in the past as well. This was an issue because apparently the names switch between nvme0n1 and nvme1n1 depending on the disk you are in?

Mounting and formatting

parted /dev/nvme1n1

And then in parted:

mkpart ARCH_EFI fat32 188GB 189GB
set 4 esp on
mkpart ARCH_SWAP linux-swap 189GB 193GB
mkpart ARCH_ROOT ext4 193GB 100%
quit

mkfs.fat -F32 /dev/nvme1n1p4
mkswap /dev/nvme1n1p5
mkfs.ext4 /dev/nvme1n1p6
blkid /dev/nvme1n1p4 /dev/nvme1n1p5 /dev/nvme1n1p6

And nano /etc/fstab:

# /etc/fstab: static file system information.
# See man fstab(5)

# EFI System Partition
UUID=AA11-BB22   /boot     vfat    defaults,noatime   0 2

# Swap

# Root filesystem
UUID=99998888-7777-6666-5555-444433332222   /   ext4   defaults,noatime   0 1

Where the UUID’s are replaced with the ones the blkid command showed.

and then I ran mount -a to test it.

mount /dev/nvme1n1p6 /mnt
mkdir -p /mnt/boot
mount /dev/nvme1n1p4 /mnt/boot
swapon /dev/nvme1n1p5

pacstrap -K /mnt base linux linux-firmware amd-ucode networkmanager nano vim man-db man-pages

Configuring yet again

genfstab -U /mnt >> /mnt/etc/fstab
arch-chroot /mnt
ln -sf /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
hwclock --systohc
locale-gen

Then I created a /etc/locale.conf with LANG=en_US.UTF-8. I also created /etc/hostname with mothership as text. and i created /etc/vconsole.conf with the same keyboard as before: KEYMAP=us

Then I set a root password:

passwd

Trying to isntall grub as bootloader

exit
exit
umount -R /mnt
mount /dev/nvme1n1p6 /mnt
mount /dev/nvme1n1p4 /mnt/boot
pacstrap -K /mnt base linux linux-firmware amd-ucode networkmanager nano vim man-db man-pages grub efibootmgr

genfstab -U /mnt >> /mnt/etc/fstab
arch-chroot /mnt
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg
exit
umount -R /mnt
reboot

Then in the BIOS, change the option that chooses which disk to use, and set it to GRUB.

And then after reboot, I was able to select Arch Linux in grub. \

POST-installation again

Basically the same as Post-Installation + Security + Graphical User Interface - GUI Graphical User Interface

useradd -m pye
passwd pye

I ran nano /etc/login.defs and changed the umask from 022 to 077. This means it has been set globally :3

Enforce delay on failed login attempts: Add the following line to /etc/pam.d/system-login to add a delay of at least 4 seconds between failed login attempts, ofc with an editor like nano:

auth optional pam_faildelay.so delay=4000000

4000000 is the time in microseconds to delay.

nano /etc/ssh/sshd_config.d/20-deny_root.conf and set it to be like:

PermitRootLogin no

su
pacman -Sy
pacman -S sudo
usermod -aG wheel pye

Didn’t work bc the internet is not reachable. Issue not connected to internet. And Issue cannot pacman -Sy. and Issue invalid pgp key

After I fixed all 3 issues, I ran the above codeblock again.

pacman -S plasma-meta

Then I found out that PYE did not have sudo access, so logging in as root.

export EDITOR=nano
visudo

and then uncomment the line %wheel ALL=(ALL:ALL) ALL

then I did all the Nvidia stuff. Make sure to do this!!!

And then basically the Starting plasma:

/usr/lib/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland

Touchdown, we have a GUI.

now, let’s make it load on startup.

mkdir -p ~/.config/systemd/user
nano ~/.config/systemd/user/plasmawayland.service

And then add this:

[Unit]
Description=Start KDE Plasma on Wayland
After=graphical-session-pre.target
PartOf=graphical-session.target

[Service]
Type=simple
ExecStart=/usr/lib/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland
Restart=on-failure

[Install]
WantedBy=graphical-session.target

and then:

systemctl --user daemon-reload
systemctl --user enable plasmawayland.service
sudo reboot

This is where I stopped last install, so let’s hope it get’s better…

It loads into tty1… what?

Issue: not connected to internet

ping 8.8.8.8

returns: Network is unreachable

ip link show

has my lo in an unknown state, my enp12so in a UP state, my wlp13s0 in a DOWN state

systemctl restart systemd-networkd

ip addr show emp12s0

Returns: → emp12s0 does not exist

nmcli device connect emp12s0

returns → networkmanager is not running

systemctl start NetworkManager

Issue, i misspelled it as emp instead of enp

ip addr show emp12s0

returns a lot of info, but only ipv6, and no ipv4.

systemctl restart systemd-networkd

still no ipv4. i also have no files in ls /etc/systemd/network/

nano /etc/systemd/network/20-enp12s0.network
[Match]
Name=enp12s0

[Network]
DHCP=ipv4

sudo systemctl restart systemd-networkd
ping 8.8.8.8

It works!!!

Now let’s make it persistent (i didn’t do the above steps, so that i’d be able to see when it works instead of constantly restarting my pc):

sudo systemctl enable systemd-networkd
sudo systemctl enable systemd-resolved

Then I opened sudo nano /etc/systemd/resolved.conf and added:

[Resolve]
DNS=8.8.8.8 8.8.4.4
FallbackDNS=1.1.1.1 1.0.0.1

sudo systemctl restart systemd-resolved

But that didn’t work, so then I tried:

sudo systemctl enable NetworkManager
sudo systemctl disable systemd-networkd
sudo systemctl restart NetworkManager

still the same issue…

sudo nano /etc/NetworkManager/conf.d/dns.conf and pasting:

[main]
dns=systemd-resolved
servers=8.8.8.8 8.8.4.4 1.1.1.1 1.0.0.1

sudo systemctl restart NetworkManager
sudo systemctl restart systemd-resolved

ERROR: failed to restart systemd-resolved.service: Unit systemd-resolved.service not found

sudo systemctl disable systemd-networkd
sudo systemctl stop systemd-networkd
sudo systemctl enable NetworkManager
sudo systemctl start NetworkManager
sudo mkdir -p /etc/NetworkManager/conf.d

then sudo nano /etc/NetworkManager/conf.d/dns.conf and pasting:

[main]
dns=none

(deleting the dns=systemd-resolved line)

sudo systemctl restart NetworkManager

It works now, and it works after reboot.

Issue: cannot pacman -Sy

pacman -Sy returns error: failed to retrieve some files

ping ping.archlinux.org returns Temporary failure in name resolution.

ip link show returns: has my lo in an unknown state, has my enp12so in a UP state, has my wlp13s0 in a DOWN state

then I did nano /etc/resolv.conf and added:

nameserver 8.8.8.8
nameserver 8.8.4.4

And then afterwards ping ping.archlinux.org worked.

Issue: invalid pgp key

When running any pacman -S or pacman -Sy, I get a message about a corrupted package (PGP signature).

sudo pacman-key --init
sudo pacman-key --populate archlinux

Troubleshooting KDE

I got the Issue not connected to internet again, so I feel like this needs to be changed better (permanently)

sudo pacman -S sddm sddm-kcm
sudo mkdir /etc/sddm.conf.d/

sudo nano /etc/sddm.conf.d/autologin.conf and then pasting:

[General]
Session=plasmawayland
User=pye

[Autologin]
User=pye
Session=plasmawayland

sudo systemctl enable sddm

This works, but the login screen is ass.

Great, now I need to add all other partitions to grub.

sudo grub-mkconfig -o /boot/grub/grub.cfg
sudo pacman -S os-prober
sudo nano /etc/default/grub

and uncomment GRUB_DISABLE_OS_PROBER=false

and then

sudo grub-mkconfig -o /boot/grub/grub.cfg

and then reboot, it indeed works.

Fixing startup qt6 problems

When I start my pc, i get 5 notificaions, and running browsers doesn’t work. They might be correllated, might not.

The notifications:

/usr/bin/kaccess has encountered a fatal error and was closed
/usr/bin/gmenudbusmenuproxy has encountered a fatal error and was closed
/usr/bin/gmenudbusmenuproxy has encountered a fatal error and was closed
/usr/bin/gmenudbusmenuproxy has encountered a fatal error and was closed
/usr/bin/gmenudbusmenuproxy has encountered a fatal error and was closed

Which is interesting.

I was able to load the error reports, and wanted to copy themn and send them to this docs via usb, but first had to install Dolphin as file viewer and Code as text editor.

You can look at my 2 crashreports here: Initial KDE crashes reports.

Both gmenudbusmenuproxy and kaccess crashed with signal 6 (ABRT) at nearly the same time (08:24:13 CEST), and both failures originate in Qt6 initialization:

  • Both crash in QGuiApplication constructor during event dispatcher creation
  • The crash path is: QGuiApplication → QGuiApplicationPrivate::createEventDispatcher() → fatal error in libQt6Gui

Possible causes:

  • Corrupted Qt6 libraries (libQt6Gui, libQt6Core)
  • Missing/broken platform plugin (the event dispatcher needs this)
  • System libraries mismatch (e.g., glib version incompatibility)

And if that is the case, it’d be best to reinstall Qt6

sudo pacman -S qt6-base --overwrite '*'

but that returned: qt6-base-6.11.0-2 is up to date -- reinstalling

then i did this:

sudo pacman -S qt6-base qt6-declarative --overwrite '*'

Which installed 2 packages. After restarting it still had the same issues at startup.

sudo pacman -Dk returns No database errors have been found! pacman -Qk | grep -v " 0 " returns nothing.

So then I tried to nuke my KDE plasma:

sudo pacman -S plasma-meta --overwrite '*'
sudo pacman -Syu
reboot

The pacman -Syu had 32 installs

After restarting it it didn’t fix the crashes, and i still cant open a browser (still don’t know if the 2 issues are related.) But I did figure out that more things have crashed, it just didn’t show up in my notifications.

Then I tried this to check whether I used wayland:

echo $DISPLAY
echo $WAYLAND_DISPLAY

but both returned an empty white-line. so then I restarted my pc to check whether there was a toggle at the login screen for wayland just like ubuntu had, and there is a toggle, but it is selected as wayland and that is the only option available.

So this is weird. Then I ran echo $XDG_SESSION_TYPE which does say wayland.

SO then I tried looking for actual errors: journalctl -xe --since "1 hour ago" | grep -i "wayland\|plasma\|ksmserver" and you can see that here: Plasma wayland Errors.

Which indicated 2 issues:

sudo pacman -S libxcb
sudo nano /etc/locale.conf

and then set this as contents:

LANG=en_US.UTF-8
LC_ALL=en_US.UTF-8

and then run:

sudo locale-gen
reboot

Then when runnin locale I had this:

$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
[pye@mothership ~]$

so I ran

sudo nano /etc/locale.gen

and uncommented #en_US.UTF-8 UTF-8.

sudo locale-gen
reboot

then that was fixed, now back to the plasma wayland thingy:

then I ran journalctl -xe --since "1 hour ago" | grep -i "wayland\|plasma\|ksmserver" again, and had this: Plasma wayland Errors II

so then i tried sudo nano /etc/environment and setting the contents to:

QT_QPA_PLATFORM=wayland

and then after reboot I still get errors, and running echo $QT_QPA_PLATFORM returns an empty line??

Okay so I have done a lot of steps and I think the main issue here is that I am asking Claude for advice on this issue, and it is probably just making it worse.

I am going to try Archinstall.

ArchInstall

  • 22/04/2026 10:15-12:45
  • Total: 21.75h

I open my pc with an arch linux install medium.

pacman -Sy archinstall

then I took an mental image of current partitions:

lsblk

and then after taking a picture, I ran archinstall

This is so much easier than doing everything manual.

But now I have the issue that ubuntu has cointrol over grub again ._., this means I cannot launch arch…

Went back into the BIOS and saw that ubuntu was on the 1st place again, so I put UEFI OS on 1st place since it is new and I assume it is arch.

This worked, now only need to install konsole, but i have no networkmanager runnign, how do I fix this?

Turns out, you can open TTY via ctrl+alt+F3.

Fix networkmanager

sudo systemctl enable NetworkManager
sudo systemctl start NetworkManager
sudo mkdir -p /etc/NetworkManager/conf.d

then sudo nano /etc/NetworkManager/conf.d/dns.conf and pasting:

[main]
dns=none

sudo systemctl restart NetworkManager

Fix grub

update grub with:

sudo pacman -S os-prober
sudo nano /etc/default/grub

and uncomment GRUB_DISABLE_OS_PROBER=false

and then

sudo grub-mkconfig -o /boot/grub/grub.cfg

and then you could choose to re-disable OS-prober for security reasons, but I do not care.

SSH

I managed to pull this repo just fine with the instructions from Git and SSH on Linux, but it keeps asking for my passphrase every single time instead of it having a 1 hour cooldown ( like on my ubuntu)

I jsut disabled the passphrase because I was too lazy to fix it.

I have also not defined a global github account with:

git config --global user.name "Your Name"
git config --global user.email "you@example.com"

Because this way I’ll get notified when I didn’t enter credentials on the repo level, which means I can check if I chose the correct account.

Firefox

and then I still cannot launch firefox and zen. LOL

but this time it is jusrt the browsers giving errors / crashing, and not wayland itself not being assigned. And obsidian does work this time, so we know it is not the same issue. Chromium does run, so it is not a browser issue, it is a firefox engine issue.

Atleast I have a browser now, that means I can install this vault on my arch (probably)

YAY

  • 25/04/2026 09:45-12:15
  • Total: ----h

Last time I have configured my KDE desktop layout etc with widgets and stuff, and also the taskbar and installing my obsidian vault.

Now I am going to install YAY as suggested by my friends.

Firefox is still broken.

Oh and my chromium keeps freezing, but I hope that is a chrome issue.

Below are the commands that the yay repo is telling me to run.

sudo pacman -S --needed git base-devel
git clone https://aur.archlinux.org/yay.git
cd yay
makepkg -si

and now I can use YAY like pacman:

yay -Syu

The reason to use yay is because it manages both pacman and AUR packages. But only the ones installed through yay. So I might want to uninstall the following apps from pacman and reinstall with yay…

  • os-prober

Yes I only used pacman once this install.

Wait, apparently yay also updates apps installed through pacman. So I do not need to do anything.

Firefox issues

lookign into it, this might be because I do not have nvidia drivers… Guess I’ll be reading the nvidia and stuff again…

Below is the nvidia section re-typed.

cat /sys/module/nvidia_drm/parameters/modeset returns file does not exist. SO there is the diagnosis on not having nvidia drivers xD

I think that this is the correct nvidia driver package for my pc (as stated before):

yay -S nvidia-open
sudo nano /etc/pacman.conf

and made sure Include = /etc/pacman.conf.d/mirrorlist wasn’t commented out ([multilib])

yay -Syu
sudo mkinitcpio -P
reboot

And then re-checking with cat /sys/module/nvidia_drm/parameters/modeset, it does return a Y, wahoo.

And this also fixed firefox (and ZEN).

I love how there are ArchWiki articles for about everything, like this article about Syncthing

The general OS installation experience

  • Installing Zen
    • Installing bitwarden extension
    • configuring layout n stuff
    • enabling sync
    • adding back all my essential tabs
    • Add back my tampermonkey scripts:
    • block a lot of annoying elements with sponsorblock.

Installing steam

I first need to enable multilib, and I’ll be followign this guide:

To enable multilib repository, uncomment the [multilib] section in /etc/pacman.conf:

[multilib]
Include = /etc/pacman.d/mirrorlist

Then upgrade the system and install the desired multilib packages.

yay -Sy multilib

Then install the steam package:

yay -Sy steam

And voilla, we have Steam on Arch Linux.

synchthing

yay -Sy syncthing

Syncthing can either be installed as a systemd system-wide service or as a systemd user service to run automatically at startup. So I did:

systemctl start syncthing.service --user

and then you can go to https://127.0.0.1:8384/ to check whether it worked.
