Apps are open because, but their window don`t show


I have Open suse as guest on VirtualBox but every time I open an app i can see that it was opened through the bottom bar, but they don`t show their GUI, so what should I ? I can`t see the terminal so I can`t open any logs.


Try to disable 3D acceleration in the VirtualBox VM settings.

Thanks that worked!!!


FYI, VirtualBox’s 3D acceleration ist still “experimental”, and it’s apparently not good enough to run KDE (either 4 or 5) yet.
