Description Mark Dawson Butterworth 2024-05-02 12:23:57 CEST
Description of problem:

With a dual Intel and Nvidia display (Dell Precision "workstation" laptop), after upgrading from mga8 to mga9 the graphical desktop failed to start. This was irrespective of which driver was picked using XFDrake. Xorg gets a segmentation fault. The problem remained on a clean install of mga9.


Version-Release number of selected component (if applicable):

mga9


How reproducible:

Every time Plasma graphical desktop starts using Xorg.

Steps to Reproduce:
1. Upgrade to, or install, mga9
2. Use an Xorg Plasma graphical desktop
3. Desktop fails to start after login screen (display freezes with login screen visible but no mouse cursor)

Workaround:

With Wayland instead of Xorg, the desktop comes up as expected.

Notes:

This problem may not actually be related to the dual technology graphics but could be the very high resolution of the Quadro (3840 x 2160)

Unfortunately this was on a mission-critical machine so I had to find a workaround as quickly as possible rather than investigating thoroughly

Thank you for the report; and sorry for the angst.
Please post the output of
 $ inxi -MSG
to summarise your system.

"The problem remained on a clean install of mga9."
Was that with the initially installed kernel, or after having updated the system (and it)?
If you have a kernal older than the latest 6.6.28-1.mga9, if possible try choosing an earlier one at boot time.
And again if possible, try reducing the resolution.
