I'm dealing with a tricky issue, which google knew no answer for. I installed Ubuntu 11.04 32bit as virtual machine in VMware Workstation under a 64 bit Windows7 host system. The surface of Ubuntu is Gnome, after I got a message, that Unity needs some 3D graphics...
Now I shut down my VM and enable the checkbox "Accelerate 3d Graphics" and started again. The VMware tools are also installed in the virtual machine.
Furthermore I tried the following suggestion: http://www.webupd8.org/2011/06/fix-ubuntu-linux-mint-theme-changing-to.html It didn't work either.
I must admit, I am no pro regarding to linux, so I think I need some help. Thanks for any suggestion!
