[SOLVED] Slackware64 -current: blank screen and computer lockup on startx, now fixed or worked around

Slackware64 -current: after updates, blank screen and computer lockup on startx, now fixed or worked around

- On Feb 5, I started my system having last updated Jan 24, except for the kernel: I was still on 6.6.11 (which was available Jan 10.)

- After running Feb 4 updates except kernel (still on 6.6.11, although 6.6.15 was available) and rebooting, I got a blank screen whether trying to launch KDE, Xfce or Fluxbox. For the first 10 seconds or so, it was possible to open another tty. Waiting any longer than that, and not only did the screen go blank, it froze and everything was unresponsive: cursor wouldn't move, Ctrl-Alt-Bkspc did nothing and I couldn't switch to another tty. I could only hard shutdown.

- I multiboot with Slackware64 15.0 on the same drive, and everything has been working well there.

- On -current, the source of the problem seems to be similar to a blank screen problem that showed up after Dec 2020 updates, tied to a kernel 5.4.x update that was fixed in a later 5.4.x (I think) update. I don't think it has the entirely same root cause(s), because back then IIRC I got a blank screen but could still open other ttys, where this time I got a blank screen and, after a few seconds, a complete lockup.

- Over the past couple of weeks, after trying a bunch of things to try to fix this, the following works, for now, with caveat below*:
LQ post [SOLVED] vtown startx not working started by @Chuck56

https://www.linuxquestions.org/quest...3/#post6191959

I created 2 files in /etc/modprobe.d, then rebooted

/etc/modprobe.d/amdgpu.conf

Code:

options amdgpu si_support=1
options amdgpu cik_support=1

/etc/modprobe.d/radeon.conf

Code:

options radeon si_support=0
options radeon cik_support=0

If this affects you, read to the end of the thread, for two reasons:
1) @Chuck56 refined his steps
2) I had to reverse the fix*

*Caveat: I doubt the durability of this fix, since later in December 2020, after the kernel was upgraded to 5.10.x, that included a fix for the original problem, I got a blank screen again. I fixed that by disabling the /etc/modprobe.d/amdgpu.conf and /etc/modprobe.d/radeon.conf files I had created earlier. @Chuck56's final post in that thread might be the way to go for a more durable fix.

2) Ran updates, including kernel to 6.6.16, which I'm still on. Same problem, although after updates and trying a bunch of other things to fix this, I got this message on screen (summarized): KDE Crash Handler closed unexpectedly... Executable drkonqi... Segmentation fault (11)

3) Add /etc/modprobe.d/amdgpu.conf and /etc/modprobe.d/radeon.conf as above. Reboot. Success!

You're using a different driver now (radeon vs. amdgpu). It might be this: https://www.linuxquestions.org/quest...ml#post6432020

That was a fun one, using Links -g on the framebuffer to find the fix when almost all websites make extensive use of Javascript and CSS.

Yeah, but...

I still don't know why, after the screen blanking happened after a Dec 2020 upgrade/update of the 5.4.x kernel, a fix was adding those radeon.conf and amdgpu.conf files... yet later that same December, after an upgrade to a 5.10.x kernel caused a blank screen again, a fix was... disabling those same two .conf files. I ran -current with those .conf files disabled from late Dec 2020 until early Feb 2024, when a fix for a new round of screen blanking (with an added helping of computer freezing) was... reenabling those same two .conf files.

This is why I wrote that I have my doubts that this is a durable fix, and I'm not marking this as solved yet. I'll keep it open in case someone finds and posts a more durable fix, or at least as long as this fix lasts a few 6.6.x kernel updates or a kernel upgrade.

Anyway, @jayjwa, thanks for the link. It showed me that keeping up with the Latest changelog for slackware-current thread is worth my while!

Still working after update to kernel 6.6.17

hpfeil · 02-19-2024, 06:25 PM

I use a laptop, HP 15-af131dx, connected to a wide-screen TV for streaming video in the living room, ripped out cable long ago. Since that foul update, I've been grasping at straws, no kde, xfce, twm. I thought of rolling back the recent updates using slackware64/ChangeLog.txt and https://slackware.uk/cumulative/slac...nt/slackware64, but that seems too much like work. Since the segfault is in Xorg, I thought of replacing the x tree with the 2nd-most-recent versions from each package. Nay! Twaddle! I created the two files that Master TheTKS mentioned, et voila! On to catch up on the decades of shows that I missed when I was a workaholic. Color me retired.

Still good after upgrade to kernel 6.6.18

TheTKS · 03-02-2024, 08:12 AM

Still good after upgrade to kernel 6.6.19. That's the most recent 3 with no black screen & freezing after adding the amdgpu.conf and radeon.conf files above.

I'll pick now to mark this solved.

I have a (possible) similar issue, however it is not resolved by using the modules configurations.
I have an old netbook Acer with AMD C-50 CPU with integrated Radeon HD 6250 Wrestler graphics. It worked well with Slackware-current with kernel 6.1.x.
Yesterday I've decided to upgrade all packages to current version with kernel 6.6.28 and now I cannot start X server at all.

Currently installed are:

mesa-24.0.5
llvm-18.1.4

I found a reported issue with Sea Islands GPUs here but it looks like in 24.0.5 the fixes were already applied and so the problem should not persist anymore. But that not the case with my GPU.

Maybe somebody can give me a hint where to dig?..

From your inxi output, it seems fb.ko is grabbing the GPU and making a mess of things. Have you got a kernel without fb compiled in? I'd expect the r600 driver to handle it from Mesa, but that's me guessing.
