Doomsday crashes on game launch since upgrading to Ubuntu 24.04LTS

JaimeC

Doomsday worked fine under Ubuntu 22.04LTS, but since upgrading to 24.04LTS it crashes every time I attempt to launch a game (Doom, Doom2, Hexen or Heretic). It doesn't matter whether I'm using Xorg or Wayland. What information can I provide to help you diagnose what is happening?

Doomsday does not work on wayland, need to use x11 compositor, maybe xwayland could work?

Launch with QT_QPA_PLATFORM=xcb environment variable. Also there's a crash with newer versions of SDL when no gamepads are connected: https://talk.dengine.net/discussion/2964/fix-for-crash-when-no-gamepads-are-connected#latest

For KuriKai: I stated in my original post that it crashes in both Wayland and X. Just tried it again to see if anything had changed but no... it still crashes.

For thesourcehim, I set the environment variabe but it didn't make any difference. I'll try connecting a game controller next.

thesourcehim nailed it: When I plugged in my game controller it did not crash! That is one STRANGE bug!!
