If Ctrl-Alt-Backspace works and the following X server works normally, it's probably stuck in a software loop. While it's hung, can you try logging in remotely, see if any process is hogging the CPU, and if so attach gdb to it and get a backtrace? If no process is hogging the CPU, try getting backtraces for the X server and the Wine process.

Other observations:

- Happens on Ubuntu-8.10 and openSUSE-11.0
- Happens only when the game is launched in full screen mode, other wise it is OK. I can use Alt+TAB smoothly to switch between windows when game is launched in window mode.

- Attaching the 'top' and 'gdb' traces for Ubuntu and openSUSE
