I have a really weird problem with VirtualBox under KDE. First to make clear - it runs flawlessly under plain Xorg, Gnome2 or Xfce, even when logging in through KDM.
The problem consists solely with KDE:
- when I start VirtualBox from a terminal inside KDE as a normal user I get a segmentation fault
- when I try starting it as root I get:
I also tried playing with the DISPLAY var. Standard value is :0, setting it to :0.0 or :1.0 didn't help either. The value of DISPLAY under Xfce is also :0 - hence no difference to KDE. Maybe KDE uses another var for elaborating and finding screens ... And what could this protocol mean?No protocol specified
Failed to open the X11 display!
Any clues?
