Comment 5 for bug 577997

I'm not sure if it's exactly the same bug, but when my X crashes (I have two displays), I can see the mouse pointer jumping violently between the edges of the two screens. I am not using user-switcher - I am just using desktop applications (some terminals, firefox, thunderbird and a touch of java).
I can't be 100% sure, but the problem appeared after installing (and rebooting to) the new kernel 2.6.32-22-generic.
I have the binary Nvidia drivers, but they haven't been a problem so far.

I will try to see if the bug reproduces with the previous kernel (I have only upgraded to 10.04 for 4 days, so my previous experience might not be concusive).

The end of my Xorg.log file is:

[mi] EQ overflowing. The server is probably stuck in an infinite loop.

By the way, I'm using Xfce, but the same nvidia driver version and kernel... Let me know if you need more logs.
