[solved] Unable to launch X or Wayland

Hello,

Since the 14h november, after my daily system update, launching a new graphical application make a segfault. After system reboot, I can’t launch graphical interface (X11 + i3 or sway) :

$ sway
Segmentation fault (core dumped)

And the x11 log: https://framabin.org/p/?645bf017cea86c2 … GBho1qtiM=

I tried to rollback some packages (linux, mesa and vulkan) without success.

I use amdgpu driver with a radeon HD 7870. My linux command line:

amdgpu.si_support=1 radeon.si_support=0 vsyscall=emulate loglevel=3 quiet

If things worked I' expect to see glamoregl being loaded.

Was this the big python 3.8 rebuild update ?

Post full dmesg / journalctl -b     output please.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: [solved] Unable to launch X or Wayland

The journalctl -b was run as user, I should have asked you to run it as root.
dmesg does give enough info to continue troubleshooting though.

Your Intel(R) Core(TM) i7-3770K has an integrated intel gpu, but dmesg & xorg log only show the amd card.
Have you disabled the intel gpu in firmware ?

What is the output of pacman -Qs llvm ?

[    4.546654] [drm] amdgpu kernel modesetting enabled.

This seems to be a bit late, do you have Early KMS enabled ?

Re: [solved] Unable to launch X or Wayland

Reinstalling llvm and llvm-libs fixed the problem.

Thank you so much for your help.
