Hello VMD users,

this morning, I tried to start VMD as usual. But instead of the normal
startup, I got a black screen and shortly after that, the KDE login page
appears. It seems like, somehow, the KDE is restartet (not the computer)
when i try to open VMD. I already did a reinstall, but without any effect.
It worked quite well at the beginning of the week and I didn't change
anything at the system since then. So I'm quite puzzled.

I'm using Kubuntu 12.04 with a NVidia Quadro 4000 graphics card. The
NVidia driver version is 310.44. Please let me know if you need more info.

Before the screen turns black, I can get the following output from VMD:

Info) VMD for LINUXAMD64, version 1.9.1 (February 1, 2012)

Any help or hints would be very appreciated.
