These results are interesting, thanks for sharing them with us.
I'm wondering if a newer xserver and/or enabling KMS would make any difference... well, you did whet my curiosity, I'll do some tests.

umh, i don't know which driver i have, i think the ones on voria repository, but i have a total time of 34.92

Is this for (the default) 100 runs or for 500 (as my timings)? If it's for the latter, I feel v-e-r-y frustrated :-/

ahnn, sorry i didn't know what "with GtkPerf (500 runs)", and i did it with the default 100.
Now i try with 500

(same kernel 31-5)

EDIT:

ahah, my overall time is 210

EDIT2:

I just installed Jolicloud on my sammy, the first thing i did is to run gtkperf (500 runs) and my total time is 120

I've just added this driver to the NC10 repository, using a different package name ('xserver-xorg-video-intel-2.8'). This way both driver versions (2.8.0 and 2.7.1) can coexist on the same repository.

To install the 2.8.0 version, use this command:

The new package will be installed, while the packages 'xserver-xorg-video-intel' (the old 2.7.1 driver) and 'xserver-xorg-video-all' (a dummy package which makes sure all the official video drivers are installed) will be removed.

To restore the old driver version, use this command instead:

which will remove the new driver and it will install back the old one.

PS:
I highly recommend to stick with the 2.7.1 version if you plan to use the official ubuntu kernel (2.6.28).
If you plan to use the new 2.6.31 kernel from my repository instead, then do your choice. At the moment the 2.8.0 version has somewhat less performance than the 2.7.1, but it solves some bugs (the most annoying is the one which causes the image on an external display to freeze after some time) and artifacts when using opengl applications with compiz enabled.

New version 2.8.1 is on repository now.

hmm i just RE-installed ubuntu netbook remix, updated with ubuntu repos, and then installed nc10-kernel and nc10-script.
With gtkperf (500 runs) i get a total time of 119

Edit:

i've just updated with voira's repo, so i think now i got new intel driver and now with gtkperf (500 runs) i get a total time of 125....

how could i know which driver i'm using?

The easiest way would be

on the command line, this should give something like

Check if the 'xorg-xserver-video-intel' package is installed. If so, you are using version 2.7.1.
Install the 'xorg-xserver-video-intel-2.8' package to get version 2.8.1 from my repository (well, 2.7.1 is from my repository too, the latest official driver from official ubuntu repositories is 2.6.3).

EDIT: Ops, I didn't notice the post from hsasshofer.

thanks

I've added another driver version to the repository: 2.9.0.
You can install it by installing the package 'xserver-xorg-video-intel-2.9'.
By installing it, any other version (2.8.1 or 2.7.1) will be automatically removed.

Hi

Impossible to use my NC10 with Intel drivers 2.8.1 or 2.9, displaying is too slow (1 refreshing in 5 seconds !). Have you an idea about this problem ?

Thanks

Are you using kernel 2.6.28? Newer intel drivers work good only when used with a newer kernel.
If you plan to continue using the kernel 2.6.28, then your only option is to stick with intel driver 2.7.1.

Instead, if you want to give a try to kernel 2.6.31, just follow instructions in this thread.

Strange, I'm using the last kernel on your repository, and all my system is updated each day...
