Description fmakosza 2019-10-20 08:19:12 UTC

SUMMARY
After logging in through SDDM with Plasma (Wayland) selected, the splash screen appears as normal and for a brief second the desktop background and icons on it show. Plasma then crashes before the task panel can appear. Likely caused by AMD Navi graphics card.

STEPS TO REPRODUCE
1. Select Plasma (Wayland) on SDDM login screen
2. Log in

OBSERVED RESULT
Upon logging into the Plasma Wayland session, Plasma crashes. KRunner doesn't start, but Yakuake does and can be used to run applications. Trying to run 'plasmashell' briefly makes the desktop background appear before crashing again, and the terminal output ends in the following:

EXPECTED RESULT
Plasma and KRunner start normally.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux, Kernel 5.3.7
KDE Plasma Version: 5.17.0
KDE Frameworks Version: 5.63.0
Qt Version: 5.13.1

ADDITIONAL INFORMATION
Problem observed after hardware upgrade to RX 5700 XT.
Dr Konqi is installed but does not launch when Plasma crashes.
Screen edge triggers work as expected.
GNOME Wayland session works as expected, so it doesn't look exclusively like a graphics driver issue.
The same issue was observed on Manjaro Linux running off a Live USB.

Comment 1 miku84 2019-10-29 08:57:50 UTC

Same for me on 5.17 Manjaro.

Comment 2 Robin 2019-10-30 17:27:14 UTC

I also have this issue, on an Arch Linux and when using Plasma (Wayland). X works for me. I also believe this might be tied to the RX 5700 (XT) GPU, as I also have it in my system.

Comment 3 miku84 2019-10-30 17:33:20 UTC

I have Radeon 5750 with free drivers with the same issue.

kcrash log of plasmashell

Not sure if useful, but issue still persists today after upgrade to Kernel 5.4.1 and an all up to date Arch.

Comment 6 miku84 2019-12-28 13:49:50 UTC

It is working now in Plasma 5.17.4.

Comment 7 Robin 2019-12-30 15:30:52 UTC

Can't confirm on my system (RX 5700), installed all updates on Arch today, still instant crash whenever using Wayland. X works fine for me, though. Is it fixed for everyone else? Then it might be a diverging issue for me

Comment 8 Ardhinata Juari 2020-01-03 17:16:39 UTC

Still crashing on Arch linux fresh install. Using plasmashell 5.17.4 and RX 5700XT

Comment 9 Syver Stensholt 2020-04-27 16:40:42 UTC

I have the same issue. Tested with both Kubuntu 19 and Manjaro KDE 19.

Comment 10 Syver Stensholt 2020-04-27 16:43:45 UTC

Sorry, forgot details;
No Wayland (I think)
AMD RX 480
Ryzen 5 1600X

The same issue happens when I log in after suspend / from lock sreen.
