Public bug reported: This is a MAJOR MAJOR usability bug that has existed in Linux for as long as I remember, however Ubuntu has some settings that make it worse.
If a full-screen game freezes but remains running, there is absolutely no way to kill it and return to your desktop. The only way out is a hard reset! This problem is caused by the fact that unlike windows, X11 doesn't treat alt-tab, (or ctrl-alt-del) as special keys, so if the game freezes you cannot alt-tab away from it. Even worse, ubuntu has disabled ctrl- alt-backspace so you can't simply kill X and start again. Finally, for me ctrl-alt-F1 et al do not work due to an unrelated bug with (I believe) plymouth. The fix is clear: change X11 so that it treats alt-tab like it treats ctrl-alt-f1 (or alternatively create a proper ctrl-alt-delete thingy). ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/905009 Title: If a full-screen game crashes there is no way to recover.
