I am having some issues with the nVidia driver on 11.0 as well. Forum format changes on some site when in the reply window. Icons on the taskbar and system tray go black, and mousing over them, will move the black from one end of the taskbar to the other. Using the driver installed from the nvidia repo.
I have that driver installed on 10.3, and occasionally get hard lock ups. I’m not sure what is causing it yet. I do suspect the nvidia driver. I have kernel 2.6.22.17-0.1-default.
I’d provide the xorg logs and xsession error logs, but I had to do a format and reinstall.
You are not the only one that have problems with this driver, i might be wrong but they sort of rushed to vomit this driver:)
I had problems with inactive windows etc. i just compiled the newest one from nvidia. Try this, just go to nvidia and follow instructions.
