Comment 22 for bug 810182

Regarding #21.
Thank You guys for trying to solve this issue, but I'm afraid I do not have to different kinds of GPU at that machine.
Indeed, it's a quad monitor setup on two identical GeForce 7300 LE using Oneiric's propriatery nvidia 280.13.
Just ask, if you need more logfiles, gdb outputs, etc... I'll post anything which could be helpful, cause it's a bad fact that (at least my own) multi monitor setups are getting worse by each release :(
