[WillemsenGithub]

After upgrading XServer Java application crashes Xserver, need to re-login

Linux Mint Xfce4, Jammy
Kernel: 5.15.0-101-generic x86_64 bits: 64 compiler: gcc v: 11.4.0 Desktop: Xfce 4.18.1
tk: Gtk 3.24.33 info: xfce4-panel wm: xfwm 4.18.0 vt: 7 dm: LightDM 1.30.0
Distro: Linux Mint 21.3 Virginia base: Ubuntu 22.04 jammy

Investigated with Internet searches and make changes to system and software

• upgrade Java to OpenJDK 21, used OpenJDK 8, 11 and 21 > same problem
• remove Mesa* > same problem
• up and downgraded Nvidia drivers > same problem
• Change Window manager and settings > same problem
• running Java from Cinnamon and XFCE (both present on machine) > same problem
• Then looked at latest updates/upgrades (grep "upgrade " /var/log/dpkg.log), found Xserver upgrades 1 day previous

The Xserver upgrade of april 5th 2024
2024-04-05 09:19:49 upgrade xserver-common:all 2:21.1.4-2ubuntu1.722.04.8 2:21.1.4-2ubuntu1.722.04.9
2024-04-05 09:19:50 upgrade xserver-xephyr:amd64 2:21.1.4-2ubuntu1.722.04.8 2:21.1.4-2ubuntu1.722.04.9
2024-04-05 09:19:50 upgrade xserver-xorg-legacy:amd64 2:21.1.4-2ubuntu1.722.04.8 2:21.1.4-2ubuntu1.722.04.9
2024-04-05 09:19:50 upgrade xserver-xorg-core:amd64 2:21.1.4-2ubuntu1.722.04.8 2:21.1.4-2ubuntu1.722.04.9

Rolled back all updates/upgrades since crash with Synaptic, Force version, and found that issue is now gone

• server-xorg-video-amdgpu will be downgraded
• xserver-xorg-core will be downgraded
• xserver-xorg-legacy will be downgraded
• xserver-common will be downgraded
• xserver-xorg-video-radeon will be downgraded
• xserver-xephyr will be downgraded
• xserver-xorg-video-ati will be downgraded
  (Using Nvidia 535 on GTK 1060, this module wasnt changed. Guess drivers like ATI and Radeon dont matter)

The error will be somewhere in

• xserver-xorg-core
• xserver-xorg-legacy
• xserver-common

By the way: cant subscribe to Xorg mailing list due to Recaptcha issues, tried 2 browsers.

Hope anyone picks up this "Message in a bottle"

Cheers
