--- Comment #1 from GyB gyebro69@gmail.com 2010-10-02 05:53:17 CDT --- I found a way to restore my desktop after the black screen, without restarting the X server: In the terminal you launched the game kill the process by CTRL+C and type blindly: nvidia-settings <Enter>. This opens up the Nvidia control panel and restores the screen. Of course, this only works if you have the Nvidia proprietary drivers are installed.
