Phoronix is a Linux technology website focusing on product reviews, distribution screenshots, interviews, and news. It is one of my favorite Linux sites and the best site for info on Linux graphic drivers. Friday Phoronix published an article detailing Ubuntu 9.10 Karmic Koala Alpha 3's Intel video driver's performance on the Dell Mini 9's, it wasn't completely positive:
"We also wanted to deliver new OpenGL results from Ubuntu 9.10 Alpha 3 using an Intel 945 IGP found in the Dell Mini 9, but that was to no avail. The Intel graphics performance was bad in Ubuntu 9.04, but at least World of Padman, OpenArena, Tremulous, and Urban Terror were able to run successfully. With Ubuntu 9.10 Alpha 3 on the Dell Mini 9 and with each of these games being run through the Phoronix Test Suite, the system would lock-up at various points. None of the tests had finished successfully even when trying to run them multiple times"Good thing misery loves company, because they said the same thing about the performance of Intel G43 chip in their test machine:
"This same problem had then occurred with the Intel G43 too. Mesa 7.5 has regressed badly in this area, but hopefully hitting in time for Ubuntu 9.10 will be Mesa 7.6 or at least more updates and patches to Mesa 7.5.x."I agree Mesa 7.5 has brought some serious regressions. Even the Mesa developers recommend waiting for the Mesa 's 7.5.1 bug-fix release. There is some good news that at the end of the Phoronix article that should bring hope to Mini 9 users:
"While it cannot be told via benchmarks, Ubuntu 9.10 is running better with Intel graphics using UXA and is certainly more stable, artifact-free, and causing less problems. As Canonical's Bryce Harrington recently shared, the bug count for the Intel driver within Launchpad has dropped quite a bit. Hopefully though these Intel 2D/3D performance problems will be fixed within the next three months for Ubuntu 9.10."I have personally found that Karmic's Intel video and flash playback performance is much smoother than 9.04. I am running Ubuntu 9.10 Karmic Koala Alpha 3 on both my Dell Mini 9 and my media box with an Intel X4500HD integrated chip and loving UXA's performance and stability for the first time since Ubuntu 8.04.
With Mesa 's 7.5.1 bug-fix or 7.6 release around the corner, there still is time for Ubuntu's developers to get Intel video driver working properly. I'd like to know how anyone else is finding UXA and Intel performance on 9.10 Alpha 3.

Installed 9.10 Alpha 3 last week. 9.04 had been experiencing both audio and video issues (skips and stuttering mostly). Forum solutions I'd found did little to fix the problem.
Alpha 3 of 9.10 has none of these issues with smooth audio and video.
Mounting does seem to take longer though both for SD cards and USB drives.
Thanks for your work on keeping us informed!
Installed alpha3 the other day. Much better performance on my eeepc (i915). Extreme tuxracer is more than playable ~20fps. The only issue I have is the the "loading" cursor flickers. I'll put up with this though considering the performance increase. I also agree with you wrt flash movies. YouTube now plays smoothly in both windowed and full screen. Can't wait till October (hopefully alpha4 is out tonight as well).
Installed a3 yesterday and it seems fine on the laptop but when i plugged my 32" samsung it got horrible and slow at 1024x786. I have to wait like 1 or 2 seconds before the 3 refreshes finish and when i click on an icon there is another waiting time of about 1 second.
Also I cannot disable the laptop's screen - either in mirror or extended!
hmm on my machine - lenovo s10 -> GMA 950 9.10 with intele new UXA drivers is MUCH slower then 9.04 ... for example screen

Compiz is very smooth - my compilation of kernel ... on 9.10 compiz workin very bad ;/ slowly ... very slowly ;/////
General Flash Playback Tweaks, until they are resolved, you can try the following. Use at own risk !
# Firefox 3.5x ( some settings can be applied to older versions as well )
about:config
# Choppy ( web / flash / Video )
# also seems to help with myspace or similar social network crashes ( media playback )
browser.sessionstore.interval 100000
# Pic Color issues
gfx.color_management.mode 0
# connection tweak to taste
network.http.max-connections 40
network.http.max-connections-per-server 30
# note: the above came from various sources, I would like to give credit to them..they know who they are....I forgot though ;-)
# General Video Play back Totem
# in this order
sudo aptitude install ubuntu-restricted-extras
#
sudo aptitude install totem-xine totem-plugins-extras totem-plugins libxine1-all-plugins libxine1-plugins libxine1-ffmpeg libxine1-misc-plugin libxine1
# remove totem-gstreamer
sudo aptitude remove totem-gstreamer
### Additional stuff that works for "" ME "" !
### Add repos for w32codes and non-free-codecs and install
### Add Gstreamer bad, ugly, ffmpeg, etc codecs
### Search for other codecs and install. lame, twolame, ffmpeg, x264, etc
apt-cache search "codec"
apt-cache search "codecs"
apt-cache search "gstreamer"
apt-cache search "xine"
apt-cache search "mpeg"
apt-cache search "ffmpeg"
### System sound - I have an older AMD ac97 board.
### multimedia selector - set to ALSA
### 9.10 versions remove pulsesaudio
### Video try replacing default with XV/X11 ( depends on the card )
### Other media players
# add any ALSA, ESD plugins ( gstreamer0.10-alsa, etc )
