Comment 12 for bug 652731

I filed Bug #658967 for ubuntu 10.10 standard and I think this might actually be the same problem. I have almost the exact same problems except mine only occur when my nvidia driver is enabled. I noticed you posted on the nvidia Bug #629910 which I was also looking at as a possible solution as enabling nvidia proprietary drivers started my issues. Do you have a 200 series nvidia card, and are you running a core i7 processor by any chance?
