X11 desktop fails after upgrade to xorg-server 1.20.9-1

VIdeo card: gt x 1070

Gdm does not start after upgrade to xorg-server 1.20.9-1. Any help for debugging will be appreciated. Thanks.

I get the following error in Xorg.0.log:

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

That's a a dual-GPU system, right?
Please post the entire xorg log and in doubt try https://wiki.archlinux.org/index.php/NV … de_setting (including the early KMS setup)

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

I have not reported the same, because it is not critical for me (switching to another TTY fixes it).

The fix has been available for several days.
https://gitlab.freedesktop.org/xorg/xse … ssues/1068
https://gitlab.freedesktop.org/xorg/xse … 43d4691779
For me, this patch fixes the bug. I checked.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

Yes it is a dual GPU, but one of the GPU's is assigned to a VM and is not accessible by arch. Also I had no issues with the Xorg server version 1.20.8-3 and below. "Nvidia-smi does not list the second GPU

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

The other aspects were not limited to the dual-gpu situation.
Lately the nvidia driver seems to be too slow™ to init the HW and early KMS has "fixed" that for several users.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

I would like to mention that arch Linux run in a container with full GPU access (using cuda) The host computer is Ubuntu. this is why the Ubuntu kernel is listed instead of the arch kernel.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

It's the same crash as linked in #3 and the very specific setup at least sounds prone to run into this.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

I enabled early KMS by adding the following kernel flag at boot nvidia-drm.modeset=1. It did not solve the issue.

When I enabled it, I was not able to detach one of the GPU cards to the VM.
I had to use a post boot script to remove the nvidia_drm and nvidia_modeset modules, then detach one of the GPUs and then reloading the 2 nvidia modules

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

Yeah, no - it's a different problem and the late kernel module would be incredible unlikely w/ the container setup.
You can either try the linked patch or wait until it hits the repos w/ the next xorg-server version.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

Hi I recompiled the xorg-server package after patching it. I reinstalled only the xorg-server package. Did not fix my issue. I guess I'll just have to wait for an update.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

Having the same issue with just a intel GPU, grabbing xorg-server-git from AUR solved the issue for me.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

@odror, ensure to no strip debug symbols and ideally compile w/ -gdwarf (for further debugging) and post the backtrace that includes the debug symbols.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

I used makepkg to compile. I loaded the source using asp command. I modified the file that needs to be fixed and then compiled using makepkg.  I did not change or modify flags.

It's also no longer a nullptr resolution, so it cannot be covered by the patch.
Either there's an additional bug in the same context or this relates more to your setup - did you change your configuration while dealing w/ the other bug?

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

Nothing was changed on my end except the update to version 1.20.9. It sounds that there is another bug.

Is this particular patch for xorg-server package or for xorg-server-common.

My system works fine with xorg-server-common-1.20.9 and xorg-server-1.20.8, but not with xorg-server-1.20.9

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

xorg-server, but https://github.com/archlinux/svntogit-p … k/PKGBUILD actually builds xorg-server-common as well.
You probably want to raise this at the existing bug report, likely same cause, different code position that blows up.

However: https://cgit.freedesktop.org/xorg/xserv … 7c0631f208
xf86CallDriverProbe doesn't seem to call xf86PlatformDeviceCheckBusID and "address 0x4" looks fishy - did you update all packates generated by xht xorg-server PGKBUILD or are you running a mix of 1.20.8 and (patched) 1.20.9 now?

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

Everything was upgraded to 1.20.9 except for the package xorg-server (using pacman). When I upgrade to the 1.20.9 I have the crash. Yes now I am running a mix system where xorg-server is at version 1.20.8. This is clearly not a long term solution.
When I tested with the PKGBUILD I installed only the xorg-server package. I Did not installed the others.

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

I did not debug this segfault. I patched xorg-1.20.9 and was glad everything was working fine.
It is possible that the cause of this error is somewhere else.

Dowgrading only xorg-server or
using xorg-server-git from AUR solves the problem as well (as long as the dep xorg-server-common-git).

Let me know if I can help debugging this (I have a laptop with Nvidia (Quadro) + Intel).

Thanks,

Re: X11 desktop fails after upgrade to xorg-server 1.20.9-1

I looked at the package from the AUR. It has older version the the prior package. 1.20.8-3. You can just use the older version from the cache directory

Thanks! This patch fixed this issue for me. I was holding back the xorg-server update for 3 days because of this problem.

Thanks for pointing odror. That is why it worked then! big_smile
I downgraded to 1.20.8-2 actually.

@r08, have you used a specific PKGBUILD available somewhere for this, or did you patched by hand!?
If there is a PKGBUILD, can you share it (with me) please?

Thanks,
