Comment 85 for bug 775060

I just clean installed 12.04 on my Dell D620 with nvidia graphics. Previously I had been running 10.04 with no problems. I get freezes quite often. I just had two happen just at the greeter login screen, and they also happen frequently after waking up from a suspend. When it happens, I can't switch virtual terminals with ctrl-alt-fn. I can log in remotely but that is it. I was able to get back to a login screen by killing the lightdm process.
