I just installed Ubuntu Unity on my desktop PC and it is very lag and annoying! Any ideas?

Did you install, the netbook version or the compiz version? – Reda Lazri Nov 13 '10 at 11:58

It happened to me too, simply, your card isn't supported! – Reda Lazri Nov 13 '10 at 15:30

Unity has known performance problems due to the mutter window manager. For this reason, Unity is switching to compiz next release - Ubuntu 11.04. You are probably better off waiting until then before using it.

Reporting a bug may help the developers. To do this press Alt+F2 and enter: ubuntu-bug unity. Follow the prompts from there.

You can get a similar interface to the Unity dock with applications such as Docky install docky.

You are probably experiencing a isolated problem. Try to report a bug at, and don't forget to offer details like: your hardware, devices, and how did you installed Unity.

Good luck!
