[SOLVED]SDDM Segfault at startup

TichShowers · 2025-07-03 23:53:56

Hello

I am encountering an issue where SDDM segfaults at startup. Resulting in a black screen and no login prompt. The issue happened rather recently after running some an update.

Right now I am getting into my system by opening a new terminal window and starting KDE Plasma manually.

Here is a Journalctl log of trying to start the SDDM:

Specifically this section is worrisome:

journalctl -b

I will admit I have tried reinstalling sddm, but to no avail, I have not even fiddled with different configuration after using archinstall. So aside from the background and some minor theme. I haven't made any changes.

The system does run Steam and I had to install some 32 bit packages, while those seem to work, I hope I didn't brick anything with that installation.

Thanks for helping

Could you please post all your AUR/externally installed packages ("pacman -Qm")?

Possible x-ref, https://bbs.archlinux.org/viewtopic.php?id=306421
Please try to get a more usable backtrace w/ https://wiki.archlinux.org/title/Debuginfod

gromit · 2025-07-04 06:24:34

Hm that looks innocent enough ... Could you try to get a backtrace annotated with debug symbols for the crash?

Full Edit: The gdb wasn't cutting it, but the KDE tool to open crash dumps apparently did the trick. I not only have 1 gdb dump but I have three.

which still lacks debug symbols, you need mesa-debug-1:25.1.5-1-x86_64.pkg.tar.zst from https://wiki.archlinux.org/title/Debuginfod

I am going to see if I can somehow force this download since gdb is showing this:

Which is worrisome. I am gonna track down if I can force reinstall these packages, since they seem to be untracked somehow.

Are you inspecting an older coredump after updating mesa?

Possibly, cause I do remember pacman -Syu'ing to get the debuginfod package not really realize that I was also updating others

Good news is, I did actually get a new coredump. And this one does have pointers in libgallium and mesa. which means, DETAILS

Please forgive me, this is the first time attempting to get these.

I did find these in journalctl that are worrying.

I don't, this is probing around for backlight control via ddc and i2c (but w/o context I can't even guess what those i2c devices are)
Have you tried to install https://archlinux.org/packages/extra/x8 … n-nouveau/ instead of enforcing llvmpipe?

TichShowers · 2025-07-05 23:30:44

I tried the second option but the login doesn't start correctly. but it does start. I get greeted by this:

So neither options seems preferable.

seth · 2025-07-06 06:30:22

The modern art approach is w/ https://archlinux.org/packages/extra/x8 … n-nouveau/ and *none* of the two environment variables exported?

GPU: NVIDIA GeForce RTX 2070 SUPER

Since you've a turing chip, are there principal reservations against nvidia or nvidia-open?

TichShowers · 2025-07-06 09:10:03

I don't actually know, when I was installing my system, I read up on the nvidia installation and misinterpreted that the GPU I had was too old and sticking to vulkan-nouveau seemed like the better option.

I installed nvidia-open and after a reboot it works fine actually, works really good. I think it might be fixed. I will also see if this fixed other stability issues with my system that were unexplained.

'key - gauge the situation and in case please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

I'm having a very similar problem when trying to install Arch with KDE and nouveau drivers hard crash of SDDM indicating a core dump in jouirnalctl

fzadikian · 2025-07-09 01:21:10

I have experienced this same issue on Arch before, and now I am having it on Gentoo (Mesa 25.1.5), so I suspect it might be from upstream.

fzadikian · 2025-07-11 04:01:33

Just in case anyone comes across this, this is currently being worked on upstream, and there is a workaround:

the upstream bug workaround wrote:

Also, does setting MESA_LOADER_DRIVER_OVERRIDE=zink change anything? There's a known bug where that behaves slightly differently from the default zink.
