Re: Nvidia 6200 and ATI RS480/482 chipset incompatibilities
Same problem here: Packard Bell pc, AMD Athlon XP 3700+, 512 MB RAM, GeForce 6200se, ATI RS480 Host Bridge (rev 10) running Ubuntu Dapper (development release), kernel 2.6.15-19-amd64-generic and nvidia drivers 1.0-8178 from Ubuntu nvidia-glx package.
X freezes at random times, even when doing nothing. Booting with nolapic seems to shorten the amount if time before lockup (kernel from breezy didn't boot with this option), no other options seems to work: noapic and anything acpi related (acpi=off and such) prevents booting completely.
Even the amount of video ram detected by the driver is wrong: under breezy it was 128 MB, with dapper it now reports only 64 MB.
GPU temperature is between 66 and 68 C at all times, but since the warning limit is set to 145 C i assume it is normal.
Updating the BIOS with the latest revision from OEM's site didn't help.
Everything works fine with Windows XP.
