What virtualization program are you running?

If you are using VirtualBox you can run apt-get install virtualbox-ose-guest-utils. You'll also need to enable 3D support under Settings > Display.

Though Unity works as expected (awesome!), there still seems to be some other bugs with VirtualBox integration. A big one for me is that seamless mode doesn't work when running 11.04.

Well it would work if you disabled unity - since unity is rendering everything as 1 display and not multiple windows the way X Windows wants.

Just did this: it works.
