Arch + gdm

Operating Systems & Open Source Linux
1

Hi All.

I am running Arch, with AMD CPU 9800x3d and 9070XT.
WM is GDM and gnome 49.

everything used to word great but since today:

After GRUB, the screen goes blank, and my monitor goes to the no signal message.
After a while:

  • if I press keys on the keyboard I have terninal which then loads to gdm
  • if I don’t touch anything it eventually loads in gdm

no idea what could be the issue, I can’t see anything obvious in dmesg or journalctl.

Pointers welcomed :wink:

to try further I tryed to:

  • edit /etc/mkinitcpio.conf to add the amdgpu module
  • edit /etc/systemd/system/gdm.service.d/override.conf

none of the those made any difference.

where should I look next to figure out what is going on?

If thr module is not blacklisted, check to see when dkms is loading thr module (at boot (initramfs), after boot once the kernel is booted and systemd is loading services).

And if it was working and was not working now, did you do a system update? If so, where the kernel, mesa, and firmware updated?

I guess all modules are loading, as the systems boots ok.

Unfortunately, I don’t have a anything newer than RDNA 2 so I cannot really troubleshoot.

It is very odd but I would imagine there is a service that may be hanging or taking to long to load. You can use boitcrl to see how long the system took to boot ant it may tell you which part of the boot process is taking longest. I am on mobile right now and walking my cat.

I can’t figure out what 1-11 could be. seems to a mb thing.

well issue is fixed. if someone happened to have a similar issue, the problem was electrical.

I unplugged the computer, turn the psu off, waited 1min. Turning it back on, the problem was gone.
I can now see that the issue was on the wifi onboard controller.
