Did a zypper dup on my Tumbleweed earlier this week. It was a rather large quantity of packages that was upgraded and I think it also involved a kernel. Since then I’m not able to logon to any KDE-sessions.
After boot I get a cli login prompt and a flashing screen. About every other second the screen goes black and then I get the prompt back again. I can ssh into the machine and everything else is working.
I’ve looked into the /var/log/Xorg.0.log and finds the follwoing entry.

How old was the snapshot you were updating from, ie very recent, or several/many snapshots ago?
and I think it also involved a kernel. Since then I’m not able to logon to any KDE-sessions.
Have you tried booting from a previous kernel?
After boot I get a cli login prompt and a flashing screen. About every other second the screen goes black and then I get the prompt back again. I can ssh into the machine and everything else is working.
Video driver problem maybe, have you tried booting with “nomodeset”?

If you believe sddm is implicated you could try removing all traces of it’s cache/config files by manually removing:
I usually run zypper dup at least once a week depending on how often I got notified about pending updates. So it was not a long time since last update.
Have you tried booting from a previous kernel?
Tried but got the same result
Video driver problem maybe, have you tried booting with “nomodeset”?
Tried now to add the nomodeset option and I got a working login.Not with correct display settings but I got a login prompt and can login to a working desktop.
As it had previously been working OK (I assume), I’d initially try another “zypper dup”, maybe a transient problem with one of the mirrors, missing a package perhaps.
OK… Unfortunately I’m not familiar with AMD/ATI/Radeon graphics, I don’t think I’m able to assist any further.
Looking at your initial post it seems that “radeon_drv.so” segfaults.
You’ve confirmed it’s a video driver problem.
Perhaps best to edit the thread title to reflect the problem is with the radeon driver after a zypper dup, then others more familiar with your hardware may reply.
The driver is quite recently updated. I dont know how long time it usually takes from compilation to distribution in an updated package. Its possible that it was included in the update I did last week.
Your Bonaire GPU almost certainly should be using amdgpu, not radeon, at least, not for X, but possibly also for kernel. Use zypper or yast to remove xf86-video-ati and kernel-firmware-radeon, and ensure xf86-video-amdgpu and kernel-firmware-amdgpu are installed, then restart. Hopefully this will be all you need to do. Possibly adding radeon.si_support=0 to kernel cmdline would help. If none of this is enough, paste here output from:
I just removed the xf86-video-ati and then everything went back to normal. kernel-firmware-radeon was not installed and xf86-video-amdgu was already installed.
I guess the update I did last week accidentally installed the ati-driver and caused the error. Now its locked out and hopefully will the system continue to run smoothly .
Another big thanks to you all that helped me to solve this one.
