I am seeing a problem that sounds identical to this with Feisty.
I am using XUbuntu with XFCE and an nVidia MX 440 videocard. The problem manifests quickly and frequently when using Firefox, but this morning when I went to my machine, the screen froze halfway through drawing the screensaver login window. I don't have another computer in that house for remote access, but am now at my Windows PC and can SSH in without problems. Doing so, "top" reports Xorg at 99.9% cpu usage.
I can reproduce the problem easily and once I get my work laptop into the same house as my Linux server I will be happy to do anything required to reproduce the problem.
