I’ve tried the Ctrl Alt F2 to open the terminal and login so I could use the ‘steamos-session-select plasma’ to boot into the desktop mode. However, clicking on ‘return to game mode’ just takes me to square 1 again
Yeah, I'm not sure myself. Stable should be latest and main unstable (IIRC), but for me the updater in Game Mode just fails to install os updates, so I might be wrong.
Just updated my bazzite deck install which also updated the bios and my install is now broken, at first it booted to the system but without audio/audio control, after a restart the system doesn't boot into desktop or gamescope, it just opens a terminal screen
