Comment 8 for bug 534847

 I don't understand what you mean by "we've upgraded the graphic drivers for kernel 2.6.32.16". Is there a newer version of the Kernel 2.6.32.16 that the one I have right now that I should download and install or should I try to reproduce the error with the same kernel I'm on right now?

I can install a later kernel if you point me to a repository or a deb package. I could compile one from source too but I would have to learn how to do it and it'll take a bit longer.
