I've been following the history of this bug. I have two machines, a desktop and a laptop, both with Intel hardware but different chipset. My laptop with a 945 video has this issue, so netbooks are not the only affected by this bug.
The fix for the perfomance regression was applied some weeks ago but some users reported freezing issues so they reverted it back. I've received an email just now about the backported patch.
It's not a Ubuntu specific bug, other distros would be affected if they include the same kernel/intel driver combination
When I upgraded to jaunty the driver performance was much better. I had not upgraded in a few weeks and when I did the performance went down the drain.
I upgraded to kernel 2.6.30 and xorg 2.7 and performance was faster than ever before (faster than feisty and earlier.) I also noticed however that flash plays RRRRRREEEEEAAAAAAALLLLLLYYYYYY slow now, but if all you want is 3d games...
Also with the updates to 2.6.30 and 2.7, everything is much faster in EXA (and less crash vunerable.)
I don't know but basically it should be possible even outsides Gentoo to do a Kernel update. I'm not sure what the packages are called in your packet manager but look for them. Otherwise it should also be a possible thing to use plain vanilla sources from kernel.org and compile them. Besides I guess as soon Ubuntu or whatever you stick with engineering team notices about all that or get enough complaints they will backport code and bring out a fix that will come to you by your standard recommended updates/security fixes. Install, reboot (unless you have a relocatable Kernel) and there you are. No need to wait for the next whole distribution upgrade.
I posted a link to ubuntuforums with everything about resolving the intel problem/pregression on jaunty default installation.
There is an official page for downloading kernel compiled packages using ubuntu configuration from vanilla kernel sources. It is just install kernel-linux package and the headers one and there you go.
Right now, it's installing a bunch of .deb packages, change the xorg.conf file to UXA (you can stick to exa if you want, but i can tell you, right now, using 2.6.30rc3 kernel or rc2, i didn't have any crashes).
So, installing new kernels on ubuntu right now is really easy to do, using those packages. Before you had to download the ubuntu configuration for the kernel, download the sources, and use the manual compilation, or any utility for the job (all of this matter can be found on the ubuntu wiki).
I have convinced my girlfriend to use linux, and she is normally very happy with it. Though since I installed the kde 4.2.2 packages onto her gnome desktop, everything has become a bit unstable. Thats freezing/hanging firefox and spontaneously reboot etc.
She doesn't know anything about fixing linux, and doesn't really care. It just has to work, and apparently it has become my responsibility :P
What should I do if thiese conditions has to be met?:
- She probably wants kde 4.2.2 again. She likes it alot.
- She want it to be stable rather than new features.
- I don't want to install intrepid with kde 4.2.2 again, as it doesn't went well the last time.
Janty was a fine candidate, but it sounds like Jaunty has some intel driver bugs (her laptop is intel based).
What should I do?
It doesn't have to be Ubuntu, but has to be debian packagement based.
