I have jaunty working on my advent 4211 (msi wind clone) and after doing a few easy things it's working way much better.
Right now, using GEM, the latest intel 2.7.1 driver and the 2.6.30 kernel almost everything is resolved. (with 2.6.29 is better, but not the best).
You can follow this thread to easily download all the files needed from the ubuntu kernel team, and downloading some files from debian sid (there's even a ppa named xorg-edge, but these files right now are more updated):
Warning: Although I have made an effort to make this guide as accessible as possible, if you are a beginner to Ubuntu then you are not recommended to follow this guide at all. Even if you stick to the safest method outlined, your system may experience difficulties due to the installation of unofficial drivers. Consider yourselves warned ;).
Overview
Some users are experiencing performance issues with Intel integrated graphics chips in Jaunty (9.04) for several possible reasons:
The
For me, it's working much better using UXA. I'll udpate to 2.6.30rc3 later ;-)
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[1]. I've received an email just now about the backported patch.[2]
It's not a Ubuntu specific bug, other distros would be affected if they include the same kernel/intel driver combination
Not only Intel, but also ATI cards, at least with R300 chip, have serious regression in 3D performance in Ubuntu 9.04 RC.
In my opinion this is very serious problem. Ubuntu is recommended as the best distributive for the users with no or limited Linux experience. What do you think? Will they stay with Linux after that?
The worst point here is that 9.04 should be released because it is scheduled for release. Who will care about all these regressions? Users?
What it sounds like is that the folks that work on and contribute to Ubuntu are not eating their own dogfood when it comes to open source graphics.
But nobody is perfect. With Fedora 10 the support for the Intel graphics was pretty poor until stuff was cleaned up with updates. With Fedora 11 beta everything seems quite happy.

I hadn't realized the R300 regression (in Mesa, I think) was showing up in Jaunty. I'll ask around tomorrow to see what the options are for getting it fixed.
This problem is particularly noticeable with the Ubuntu Netbook Remix launcher, on systems such as the eeePC 900.
