I have a Dell Latitude E6400 laptop. I've had Ubuntu 10.04 64-bit working for years. I decided to update to 11.04 (via 10.10) and it's fine except Unity won't load. I get the backdrop, the WiFi network notification, and I can see the mouse pointer. Ctrl+Alt+Delete gives me the restart/shutdown/etc. options.
If I select Ubuntu Classic at the login screen, it loads fine. I've tried fiddling with a few
ccsm settings but it makes no difference. I've disabled GNOME compatibility, and enabled the Unity plugin. If I type:
from classic mode it loads up Unity, suggesting there's no obvious problem with the drivers. There are some error messages but I lose the ability to move windows around at this point and I don't seem to be able to cut/paste the messages.
I did fiddle with Compiz in the past to get the appearance menu to allow me to select
none for animations and have it stick. Perhaps I have to uninstall/reinstall something?
This is very annoying - it seems like I'm very close to having it working but I don't know what to try next. Any suggestions?
