--- Comment #7 from Michel Dänzer michel@daenzer.net --- (In reply to Maxim Sheviakov from comment #5)
Umm, the game doesn't hang the system. It's about the game's process not to respond at all - I can simply go to desktop and kill the process. I don't think that gdb attachment would help either, [...]
Of course it would; it would show us whether it's hanging in game code or driver code. From José's comments it sounds like it's likely the former though.
