Possible ubuntu video driver bug

[Dazed_75]

Try looking to see if you are using the open source generic nvidia driver
or the proprietary one.  I am not sure where that is in the Kubuntu menus
but look for something in System, or Administration with a name that is
probably something about Hardware.  It should run a program that looks to
see if there are proprietary drivers you might choose to use.

I AM curious though if you have some particular reason for suspecting it is
due to you having that video card since a screen freeze could be something
above the driver level.
