Comment 194 for bug 456902

I have a similar issue. After a while X freezes up and nothing works on the graphics part, but behind for instance I can log in into the machine using OpenSSH. I tried disabling the DRM with nomodeset but still the drm, i915 modules are loaded into the kernel (I tried to blacklist them also) and the issue remains. My video controller is VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01) and the lspci output is:

00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 01)
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)

and the computer is a HP rp5000 model and the OS is Ubuntu Karmic Koala. Because of this random freeze ups the machine is unusable for work. Is there some workaround that solves this issue? Thank you!

P.S. I read all the comments on this bug and tried most of them except package updates (I'm very conservative about those methods because this is my work machine).
