I upgraded from Maverick to Natty and then the mouse wouldn't click. It wasn't frozen, I could move the pointer, but none of my clicks registered. In the login screen I selected the Ubuntu Classic without the Compiz effects, and this lets me in and everything works fine (except Compiz, that is). But any time I try to log in with Unity or with the effects on the mouse will not click.

I'm using the current NVidia driver for my GeForce 7300SE with an Acer S211HL monitor set at 1920x1080 60Hz. This configuration worked perfectly under 10.10 and 10.4, even with all of the Compiz effects.

I tried backing up my data files and installing 11.04 fresh, formatting the drive. Same problem. I can always get in with the effects off, but any time I try either Unity or the Classic with effects on I can't click on anything with the mouse.
