Update: After some usage of different wine apps, suddenly the audiodriver of my computer died, and then Team Fortress 2 worked kinda, no GUI (Neither background in startmenu of Team Fortress 2 or ingame GUI) After reboot it doesnt work, again... Last time i started, i used : cd ~/.wine/drive_c/Program\ Files/Steam && WINEDEBUG=-all wine steam -applaunch 440 to start TF2 , could that be why it didnt work? Thanks
