Comment 5 for bug 982268

Begining to suspect this is a NVIDIA driver and / or hardware problem.
My motherboard is now getting on for six years old and am using the onboard graphics which, according to the NVIDIA site "should" cope with the onboard graphics..............
I've been trying 12.04 due to occasional system lockups in 11.10. These are usually shown by the screen remaining blank, if it's during boot, or by the screen going crazy. 12.04 is also doing it.

Have been trying a few options which have involved installing, re-installing, re-re-installing, installing older versions and upgrading in place, etc.
My "live" 11.10 system was built doing a roll forward.
Today I've cut a 11.10 CD, installed it, lowered the NVIDIA driver to level 173 and installed all updates.
I should now have two 11.10 partitions, one of which I will probably roll forward to 12.04 once I'm happy that both partitions are relativly stable and that I've got something to fall back on in case of problems.
