I checked and found where it suggested a proprietary driver and offered one other. I chose the one that was recommended. The bug showed itself with the driver that came with the install and the one I installed later. > 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. I've had that card for about 2 years while the machine was running XP and didn't have this problem. It only showed itself after I installed the latest Ubuntu and Kubuntu version as well as the other latest linux flavors I mentioned earlier. Fedora 15 was the worst. It would freeze the screen as soon as I started playing a video. The others would let me watch at least for a few minutes before the screen froze. Also if it's not a driver problem, what else could it be? > > On Thu, Nov 10, 2011 at 3:59 PM, Derek Trotter > > wrote: > > I have an NVIDIA Geforce 8400 GS card that plugs into a PCI slot. > I have no problems with it in XP, but when I installed Kubuntu > 11.10 I found a problem.
