Description paul.geisler 2010-04-30 15:55:55 UTC

After running some bad resolution changing fullscreen application, the user set desktop resolution is not restored on quite many occasions. 

This is frequent if the display changing application is terminated abnormally (crashed, killed). 

Several bugtrackers are full of "desktop resolution wrong after running xy" complaints. This cannot be blamed to bad programs any more. The resolution should be handled just like memory or file handles - if the screen posessing process gets terminated, the OS / xserver should take care of restoring the desktop.

    DGA: Track client state even when using old style DGA.
    
    This fixes the issue that a badly killed DGA will keep on hogging
    mode/framebuffer/mouse/keyboard.
