[2.0.66] Game crashes on launch
Posted: Sun Sep 21, 2025 5:26 pm
Hi everyone, while playing factorio my main display turned itself off with no apparent way of recovering. This cascaded to my side monitors after a few minutes.
After rebooting my PC, factorio crashes on startup and tells me to post the log file here. Any troubleshooting help would be appreciated.

Edit: I have seemingly fixed the error by switching to wayland over X11. Leaving this topic open in case someone still wants to look at the error dump
