Description:


Since linux 6.4.0 (6.4.1 and 6.4.2 too):

1. boot to vanilla kernel
2. enter luks password
3. systemd starts
4. when reaching the graphical target, sddm-greater crashes, I no longer have any video signal, my displays are going into sleep mode

While using linux-lts 6.1.38

1. boot to lts kernel
2. enter luks password
3. systemd starts
4. sddm greater displays correctly

In journalctl I can see "systemd-coredump[1035]: [🡕] Process 986 (sddm-greeter) of user 975 dumped core."

> no longer have any video signal

You should be checking the journal for signs of GPU driver crashes.

> Full stack trace

Basically useless without debug symbols [1]. It's usually as simple as:

$ coredumpctl gdb (then answer y when it asks "Enable debuginfod for this session?")
(gdb) set logging enabled
(gdb) bt (or bt full)

Then post gdb.txt

Comment by Alexandre ZANNI (noraj) - Sunday, 09 July 2023, 19:25 GMT
The thing is that despite the crash, I see no error (error level) from the previous boot on the logs with `journalctl -b -1`.

However, I can see some warning level logs `journalctl -b -1 -p warning` (boot-1_warnings.log) for amdgpu, sddm-greeter, sddm-helper and sddm. (the 2h timing shift in the log timestamp is due to the hardware clock and the ntp sync in between during the init).

Note: the previous pastebin was actually from the LTS boot, not from the crashing vanilla boot.

Full last boot (journalctl -b -1) logs (boot-1_full.log).

Sorry, I hadn't the debug symbols installed, here is the proper gdb trace.

You are running some third party "Sweet" theme. This is not from Arch and therefore not supported...so this is definitely not an Arch packaging bug.

sddm[640]: Loading theme configuration from "/usr/share/sddm/themes/Sweet/theme.conf"
Comment by Alexandre ZANNI (noraj) - Tuesday, 11 July 2023, 07:31 GMT
This has nothing to do with the theme used. The proof is I set back the default breeze theme and the same crash occurs.
Comment by Toolybird (Toolybird) - Tuesday, 11 July 2023, 07:35 GMT
Well, this is a fairly popular pkg and nobody else appears to be having the same problem. You should probably report this upstream. Please ensure to give them a backtrace with debug symbols.
Comment by Alexandre ZANNI (noraj) - Tuesday, 11 July 2023, 09:17 GMT
Maybe this is not something between the kernel and SDDM but between the kernel and my graphic drivers for my specific hardware and the SDDM crash is just a consequence.

Comment by Alexandre ZANNI (noraj) - Tuesday, 11 July 2023, 10:06 GMT
The more I think, the more I start to believe the fact that I have no signal on linux 6.4 is unrelated to SDDM but related to the AMD graphics and maybe display port changes in linux 6.4 https://kernelnewbies.org/Linux_6.4. With the AMD graphics changes on 6.4 many people reports bad gaming performance but for my case it may as well end up with no signal at all. Anyway looks like an upstream issue. I have no clue hopw to troubleshoot that since I have no amdgpu error in journalctl.

I have am having a weird issue with SDDM crashing on 6.4+ as well, with amdgpu drivers. GDM has no issues. Not sure if it is specific to certain hardware configs (7900xt, 12700k). I also haven't tried changing sddm back to a x11 session yet. Just been fine using gdm for the time being. I can boot on older kernels before 6.4 as well.
Im new to the community and have been using arch for about 7 months now so it could be something I just messed up on my end. Your experience does seem extremely similar to mine, so I thought Id share.
Comment by Alexandre ZANNI (noraj) - Monday, 17 July 2023, 18:06 GMT
@Taylor: Unrelated to X11 or wayland, happens when both are predefined as default and anyway the crash occurs before opening a session.
Comment by loqs (loqs) - Wednesday, 19 July 2023, 20:26 GMT
Please try with linux 6.4.4. If the issue is still present please try 6.5-rc2 or rc3 if available. If that still has the issue please try [1] if the issue is still present please bisect [2] between 6.3 and 6.4 and report the issue upstream [3].

linux-6.4.4 and linux-zen-6.4.4 not working.
linux-mainline (6.5-rc2) not working either (kernel drm warning logs attached).
linux-drm-tip-git (6.5.r1200134.003f860e5577-1) and linux-drm-next-git (6.4.r1188951.6725f3322807-1) are not working either.
linux-amd-drm-next (6.4.2023.05.31-1) and linux-amd-staging-drm-next-git (6.2.r1160341.2514cae86fce-1) are not working. Note: having inux-amd-staging-drm-next-git not working while it is 6.2.x indicates that the crash must comes from an AMDGPU update that was introduces on 6.4.0.
Comment by Alexandre ZANNI (noraj) - Saturday, 22 July 2023, 22:31 GMT
Since none of the kernel worked, I have to git bisect to report upstream.
If I understand correctly to bisect I'll have to re-build the kernel from git for each commit. Since building `linux-amd-staging-drm-next-git` took me an entire day, bisecting will take me an eternity. I know all unnecessary drivers (network, sound, printer, etc.) could be disabled using modprobed-db to speed up the build time but I don't have the skills to do that.

Note: I see my bootloader (rEFInd) resolution at 1920*1080 in both cases, but it seems that I see the systemd boot logs at 19020*1080 on failing kernels and at a default 640*480 or something for all working kernels. It may not be a coincidence and is maybe related to the video driver issue.
