Xorg.conf

Switched the default xorg.conf file to include...

Option "AccelMethod" "uxa"
...and it seriously improves performance, up until the point that it randomly creates a freeze, which requires a reboot to bring back any responsiveness to the system. 

The screen contents remain and the mouse pointer moves, but nothing else responds to keyboard or mouse input.

You are using an old driver and old kernel, which doesn't support UXA well.

Various UXA fixes have been added in the new code. Could you try xf86-video-intel 2.8.x and kernel 2.6.30 or 31-ish? Ubuntu Karmic Alpha or edger could be a good candidate for you. 

Please file new bugs with new drivers. Thanks.

Thanks for the suggestion, Gordon. 

Is there an approach to safely try the updated software you suggest without rolling my distribution forward into peril, (and preferably with a rollback option)?

I'm shy of updating to Karmic before it's considered stable as I'm attempting to use this machine for my daily bread and it's otherwise very satisfactory at present. I was happy to try switching xorg.conf and risk a few hangs, but permanently replacing the build is too much.

One of the reasons I recently switched from Intrepid to Jaunty was more stable graphic driver support for Intel chipsets, but apparently there was not enough improvement, so if I try Karmic I'm facing yet another upheaval for an unknown benefit. 

I feel I could be chasing my own tail to keep advancing distributions in order to improve stability in one respect whilst losing stability in many others, so another less-destructive option would be welcomed.

Update, I've now attempted to run UXA with 2.6.30 after finding .deb files for this kernel at kernel.ubuntu.com. 

I upgraded my xf86-video-intel to 2.2.7.1 based on the latest update I could get from the main Jaunty repositories.

To thrash the system, I have compiz enabled with random effects, and after loading 20 arbitrary firefox windows I tried to run this pair of command lines which causes desktop effects with minimisation of all windows followed by maximisation, and it died on the second one...

wmctrl -l | awk '$2=="0" {print $1}' | xargs -n1 xwit -iconify -id
wmctrl -l | awk '$2=="0" {print $1}' | xargs -n1 xwit -pop -id

...which I will try to recreate in a moment and report back.

Any suggestions how I can update to a later xf86-video-intel without the Karmic upgrade would be welcome.

I'm not the correct person to answer how to upgrade Ubuntu. Maybe you can try liveCD?

What I heard is many Ubuntu users said the intel driver 2.8.0 (went into Karmic Alpha3) is much better than before.
