I'm running 11.10 (3.0.0-19) and for a while everything was working just fine, but then some keyboard shortcuts stopped working and I left it alone since it wasn't bothering me. Now its literally pissing me off the keyboard works just fine then it starts acting up.

it locks up
backspace doesn't work
random letters start showing up

now the mouse won't left click... Everything works just fine on windows but I don't want to format the ubuntu drive since I got everything how I want it... I'm wondering if for some reason the keyboard process is conflicting with something.
