I just got a fresh copy of the linux driver from Nvidia the other day and my desktop is finally working with desktop effects enabled. I wasn't able to get much sucess using the kmod-nvidia route. Using the manual install of the Nvidia driver works for me *much* better. Of course, this also means that every time the kernel updates I have to re-run the shell script, but I can handle that minor annoyance to have a working, stable desktop. Cheers, Gar ----- Original Message ---- * Random X crashes when using desktop effects, when KDE 4.1 was largely okay, though I could be blaming it unfairly on KDE - maybe it's an nvidia driver issue.
