Unity won't run on my new Ubuntu 11.04 install (with a Nvidia GeForce GO 7400). Ubuntu classic desktop works though, I tried all different drivers provided in the repositories. Doing System->Administration->Additional_Drivers gives me a "This driver is activated but not currently in use." warning.
I even tried the Nvidia driver from the official Homepage.
After some googling I found the tool
/usr/lib/nux/unity_support_test -p which tells me that my card is blacklisted. The other tests show a green yes.
Is this a bug or is my card too old which would be pretty surprising for me :P ?
