I don't know if the fact that I'm running 11.04 in a virtual machine has anything to do with it, but I can't get Unity to start. No matter what I try, I still get the Gnome desktop. I've checked that it's really 11.04 and I see Ubuntu as the session choice at the log-in screen.
This is an upgraded 10.10 installation. Also, on first startup, I'd only allocated 512M and saw the message saying Unity had been disabled because I didn't have the appropriate hardware. So I increased the allocation to 2G and tried again. I've gone to terminal and entered unity --reset, all to no avail.
Help! Any ideas?
