Comment 33 for bug 109643

Hey, I'm adding a comment here as it seems I have a very similar problem. I'm running Ubuntu 7.10 for desktop, I've just switched from Windows few weeks ago. My system is:

AMD Athlon X2 4400+
ASUS M2N-VM DVI (GeForce 7050PV integrated video on nForce 630a)
ADATA 2GB 800MHz DDR2

I've installed NVidia driver through the Restricted Driver Manager. While using Gnome with full hardware acceleration (the mode with additional visual effects) my system hangs after few minutes and screen fills with skewed multicolor stripes (just like described here <a href="https://bugs.launchpad.net/ubuntu/+bug/109810">Bug #109810</a>). If I run Gnome without visual effects, the system works fine (or so it seems).

Looks like this problem is video related somehow (or video application triggers it). When I launch some video application, like World of Warcraft (running with Wine), the game often hangs on random basis. Usually in first minute of application running. Such lock up needs a hard reset. Sometimes everything runs fine without hanging so this issue is a bit random.

I've read that this can be caused by Cool'n'Quiet feature of AMD Processors, but at this moment I'm not sure if such feature is turned on in my BIOS. Once I'm back at home I have to check it. TBH this problem is driving me mad, I really hope that disabling CnQ would help, at least for now.
