[Christian Mattes <chrmattes@xxxxxxxx>]

Hello,

Bumblebee basically works fine for me, the only problem atm is that, as 
soon as the Nvidia X-Server is started for the second time it crashes 
and remains neither restartable, nor killable until reboot.

    Example:
    `optirun glxgears`
    [ctrl]-c to stop glxgears
    `optirun glxhead` => Error

The on/off-switching of the Nvidia card itself doesn't seem to cause the 
problem, as calling the on/off-scripts (which are based on the 
test_off.sh included with acpi_call) has no effect at all...
After the crash the screen changes to a console displaying a cryptic 
error message (attached) and switches back to my desktop after a second. 
Xorg.8.log and Xorg.0.log look all fine.
Preventing the shutdown of the Nvidia X-Server works as a quick fix... 
wouldn't mind a real solution though.

Christian
