I’m facing several problems since my last update of today : first, my graphical interface didn’t show after reboot. I can login (tty). I can manually launch a graphical session (startx /usr/bin/startplasma-wayland or x11) but, then, my hardware configurations are wrong (shown window doesn’t cover all screen, undetected buttons of the trackpad).
I don’t know what to do to restore my previous system which was very stable for several months.
Welcome to the community @ebm 
Could you please share the links these commands output, with us.
Your system information:
inxi -Fxxc0z | eos-sendlog
Your boot log:
journalctl -k -b -0 | eos-sendlog
There might be filesystem corruption:
FAT-fs (mmcblk2p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
The zram isn’t loading properly too.
I’ve run fsck as asked, and I’ve changed the algorithm to lzo for zram : https://dpaste.com/HDJVQE5BH
I’m assuming that the issue isn’t fixed. What packages did you upgrade during the previous upgrade which messed up the system?
grep "2026-04-07" /var/log/pacman.log | grep "upgraded"
Change the date to the date you upgraded and run the command. We can try to diagnose the problematic package
Thanks @sradjoker, here is the content of the list of upgraded packages, only a few days after the previous successful update : https://dpaste.com/A5L8HKVYW
There is a new host serving aarch64 at the following url where you can roll back. You will just have to find where you need to roll back to looking at your pacman log after you had the last good update:
https://pkgmirror.sametimetomorrow.net
Quote from arch-arm forums:
If you want to roll back to the 08-Mar-2026 snapshot for example, edit /etc/pacman.d/mirrorlist to comment your usual mirror and replace it with the following:
https://pkgmirror.sametimetomorrow.net/$arch/repos/2026/03/08/$repo
Then just issue:
pacman -Syy && pacman -Syuu
This could be a temp fix until some one figures out what package is breaking the install. Of course it will not roll back any EOS packages that was installed.
Good idea. I’m having a hard time completing the process though because of a lot of error 429 during download.
The link was posted yesterday on the forums. That is a server issue of too many requests at the same time due to high traffic. Might be to too many people trying it out. Could wait and try again later. Here is the link to forum in case something is added. Look for @graysky post.
After reading SDDM fails to start on Pinebook Pro , I replaced libdrm-pinebookpro with libdrm (ie install libdrm and choose to remove libdrm-pinebookpro when asked to resolve the conflict).
Then, here is what I (and chatGPT) did to get my system back :
For some reason, GLX was broken so
sudo pacman -Syu
sudo pacman -S --overwrite="*" mesa mesa-utils libdrm libglvnd
sudo pacman -S libx11 libxcb xcb-util xcb-util-image xcb-util-keysyms xcb-util-renderutil xcb-util-wm xcb-util-cursor libxkbcommon-x11
sudo pacman -Qkk mesa
in order for glxinfo | grep “OpenGL renderer"to mention Panfrost, which it didn’t.
