Description Sorin Toma 2022-07-01 21:29:23 CEST

Description of problem:
XFCE "freeze" while starting. The mouse cursor, with hourglass, remains functional.

Nothing visible wrong in journal: https://pastebin.com/U7dd76cT

On an HP Elitebook 2540p switching to init 3 segfaults xfce-session https://pastebin.com/Xw2PWE7S

No segfaults on Dell Latitude 5520, nor on Latitude E7470.




How reproducible:

Every time. Tried on three different laptops.

Steps to Reproduce:
1. login to XFCE
2. admire the frozen screen while being able to move the mouse cursor.
3. kill X

Bug confirmed. Killing X with alt+ctrl+bs twice and then logging in again
from sddm, desktop does start. Looks like a timeout during first attempt
to start the xfce session that works ok after restarting X.

Assigning to Wally who maintains xfce4-session.

Using run level 3  and then "startx startxfce4" has the same problem, but
the workaround doesn't work.

Comment 3 Jani Välimaa 2022-07-02 10:36:01 CEST

There have been no changes in Xfce pkgs since a long time.

Only pkg changed lately is libx11 and indeed reverting back to libx11-1.7.5-1.mga9 fixes the issue. Further investigation is needed.

Comment 4 Jani Välimaa 2022-07-02 10:52:28 CEST

The problem seems to disappearing if libx11 1.8.1 is build with --disable-thread-safety-constructor.
