Description aalsing 2019-10-26 15:54:49 UTC

Application: plasmashell (5.16.5)

Qt Version: 5.12.5
Frameworks Version: 5.61.0
Operating System: Linux 5.3.6-300.fc31.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

Login using wayland

- Unusual behavior I noticed:

When logging in with wayland a black screen appears and no response comes from the computer, I can only switch between tty (ctrl+alt+number).
When not using wayland the os login without issue, when using wayland the page one (ctrl+alt+1) shows the login page, while page two (ctrl+alt+2) shows the black screen and sometimes I can shutdown the computer with logging in to tty3, but this is not always the case. The system is newly installed with nothing else installed from the standard fedora installation but steam and dota2.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 4 Nuno Costa 2020-03-14 20:44:52 UTC

Just adding that I have a laptop where I do not see this crash.
The crash only happens on my desktop.

Both have Fedora 31 fully updated as of today.

On my desktop I'm using and Radeon 5700 with a 4k monitor.

My laptop is using an integrated graphic from Intel i5-3320m CPU on a 1366x768 screen.
