RevertingIntelDriverTo2.4

Revision 97 as of 2009-05-02 17:52:02

Clear message

The problem

As Described in X/Troubleshooting/IntelPerformance, some laptops with intel graphics hardware experience a serious performance degration after upgrading from intrepid to jaunty. The reasons for that are already explained on that page. This page explains how to revert the driver to the version in intrepid.

Installing the package

Add the following lines to your /etc/apt/sources.list:

 deb http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
 deb-src http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main

Import the appropriate GPG key:

 sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xce90d8983e731f79

See https://help.launchpad.net/Packaging/PPA#Adding%20a%20PPA%20to%20your%20Ubuntu%20repositories for additional information how to add GPG keys to your system.

Install the driver:

 $ sudo apt-get update
 $ sudo apt-get install xserver-xorg-video-intel-2.4

Now you should be set. Restart X and see if the graphics performance from intrepid is restored.

Do I need to change my xorg.conf file? ==> May not work. Situation not improved without xorg.conf change??

Rolling back

If the driver does not work for you, or is not better, you should rollback to the original Ubuntu one. Remove the two lines from /etc/apt/sources.list again, and install the original one again:

 $ sudo apt-get install xserver-xorg-video-intel

If X.org does not start at all, you should change to a text terminal by pressing Ctrl+Alt+F2, logging in, and use "sudo nano" to edit /etc/apt/sources.list. After installing xserver-xorg-video-intel, restart the computer with "sudo reboot".

Chad Rodrigue

DRI: Check. Compiz (or Metacity Composting): Check. Videos playable on youtube and totem: Check. Tearing and corruption: gone. Still a little slow on full-screen refreshes (min/maximizing windows), but this driver is a godsend for this chipset, which is awfully laggy and has no DRI in Jaunty's default 2.6 driver.

Oliver

Everything running smoothly now

[8086:2572] (rev 02)

restored-ish

Zorael

Roughly the same as I had in Intrepid, ~6-7x what I have with 2.7 drivers from git. A+, would download again.

[8086:2592] (rev 03)

significant improvement

alt

Compiz works much better, but still have lots of odd lines everywhere in Blender

[8086:2592] (rev 03)

No improvement

prunus dulcis

No change. Still can not enable Compiz. Blender interface still not usable (see https://bugs.launchpad.net/ubuntu/+source/blender/+bug/360415). Ubuntu 9.04, kernel: 2.6.28-11.

[8086:2592] (rev 03)

Back to Intrepid performance - great fix. Thanks

[8086:27a2] (rev 03)

No improvement

Radomirs Cirskis

No noticeable improvements. Still cannot access drivers. Compiz doesn't work. Playback in full screen is hopeless. Ubuntu 9.04, kernel: 2.6.28-11.

[8086:27a2] (rev 03)

No Improvement

Matt0001

Full-screen Flash video (Hulu) extremely choppy.

[8086:27a2] (rev 03)

Performance worse

progre55

the same as "NB", glxgears shows "Failed to initialize GEM. Falling back to classic." Performance is a little worse than it used to be.

[8086:27a2] (rev 03)

No improvement

NB

Still poor performance: glxgears shows "Failed to initialize GEM. Falling back to classic.". The performance is better than default Jaunty settings and it's comparable to Jaunty+UXA or Intrepid+EXA, that is 3-4 times slower than Hardy or Intrepid+XAA. Compiz works (default Jaunty lags, Jaunty+UXA works well on Compiz). Extreme Tux Racer displays 0.5 to 1.8 FPS, compared to 5-7 In Jaunty+EXA+MigrationHeuristic "greedy" and to 9 to 24 of Jaunty+UXA. 2D redraw lag is noticeable, maybe worse than Jaunty+UXA. Ubuntu 9.04, kernel: 2.6.28-11.

Juan Marulanda

Videos are playable again, compiz is still slow, but not a lot compared to 2.6 driver. Still, there may be even more improvements with Kernel 2.6.30

michael_wigren

compiz/metacity performance is back on par with Hardy (I didn't test Intrepid).

[8086:2a02] (rev 03)

slightly worse

Laurent

With the normal Jaunty driver, at least with no open Windows, the Compiz effects were fluid. Now, I experiment lack of performances even with no open windows. Apart of that, no change (even after reboot).

[8086:2a02] (rev 03)

performance worse

Joshua Kite

"Desktop effects could not be enabled" (Compiz). Full screen video performance okay for about half a second, then screen dims and full screen videos are jerky. Was fine with Intrepid

[8086:2a02] (rev 03)

preformance improved

Jo-Erlend Schinstad

Metacity performance is greatly enhanced. Compiz still won't run because the device is blacklisted (skip_checks doesn't help): http://wiki.compiz-fusion.org/Hardware/Blacklist

[8086:2a02] (rev 0c)

performance worse

AlwinGarside

Benchmarking shows a 50% performance decrease when switching to the 2.4 driver. I recommend sticking to the new driver and disabling Compiz to prevent freezes (should be disabled in the latest Compiz updates).

[8086:2a02] (rev 0c)

performance worse

mackdieselx27

PPRacer was about 18-20 FPS with the 2.6 driver + greedy migration and 4-6 FPS with 2.4. Everything else was choppy all around so I reverted back to 2.6. Xorg continues to hog 30% of the CPU.

[8086:2a02] (rev 0c)

performance worse

TomChiverton

Xorg uses 30% CPU, like the 2.6 driver does when used with no UXA option. Under 8.10 all was fine.

[8086:2a02] (rev 0c)

Performance worse

Nicolas GRZ

"Desktop effects could not be enabled" (Compiz). Was fine with Intrepid

[8086:2a02] (rev 0c)

No improvement

tcpipfddi

No noticeable improvements. Unable to activate Desktop Effects with either driver (HP 6710b, X3100). It seems that the picture is shaper/clearer with the 2.4 driver installed.

[8086:2a02] (rev 0c)

No improvement

Chanchao

No change. Can not enable desktop effects. This is a Thinkpad T61

[8086:2a02] (rev 0c)

DTD

No improvement. Can not enable Compiz. Ubuntu 9.04, kernel: 2.6.28-11.

valereo

No improvement. Ubuntu 9.04 RELEASE. glxgears: Failed to initialize GEM. and about 200fps against 1700 in 8.04.2, xorg still high using CPU up to 50-60% when moving windows or scrolling smth

[8086:2a42] (rev 07)

performance improved

Lure

much better performance than 2.6 driver with EXA+greedy or UXA, only problem is that it gets physical size of my 12.1" panel wrong (have to use xrandr --fbmm to fix it manually)

[8086:2a42] (rev 07)

Performance worse

djuliette

rollback made desktop effects even slower, went back to 2.6. Everything was fine in 8.10

VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

No improvement

ryantm

Continued constant high CPU, no noticeable improvements. glxgears below 30 fps, GLXgears reports GEM could not be started reverting to Classic Mode Ubuntu 9.04, kernel: 2.6.28-11.

Andy Walker

CPU Levels now acceptable - performance is back to pre-upgrade levels

[8086:2a02] (rev 03) ASUS F3E

Performance worse

Karunadheera

Was fine with Intrepid. Could only enable 3D Desktop effects by adding SKIP_CHECKS=yes (normal driver also same). Effects were flickering when moving windows. "Option AccelMethod uxa" did not change performance (normal driver is much better with this option - but causes X hangs sometimes).

[8086:27a2] (rev 03)

Seems for be fixed

bhoult

Performance back to normal on Mac Mini.

YAY!! My wobbly windows are back!!

[8086:2a02] (rev 0c)

Performance restored!!

Patola

Performance of Kubuntu + KDE Effects feels *almost* as good as in 8.10, however when I tried to play my newly installed Penumbra Black Plague, the game performance was completely unacceptable. Went back to xserver-xorg-video-intel 2.6.3-0ubuntu9 and the game performance was restored. Well, now I have to keep switching back and forth between 2.4.1 (when I need to work) and 2.6.3 (when I need to play) until this bug is completely solved...

[8086:2a02] (rev 03)

Disaster

ReedMace

No graphics at all. Was fine under Intrepid (including wobbly windows!). X-server log reported "(EE) intel(0): Output LVDS enabled but has no modes; (EE) intel(0): No valid modes; (EE) Screen(s) found, but none have a usable configuration." Had to rollback to Jaunty driver using nano (thanks for the instructions) so still have original problem (an inch of blank screen either side of display area)

Fran├žois-Xavier Thomas

Thanks a lot! Same performance as 8.10, only a bit slower. I had some trouble playing huge HD movies and noticed that Xorg was eating ~30% CPU, though.

bartybot

I can watch an HD video now without crashing X. Still hates 3d with a passion.

[8086:27a2] (rev 03)

Performance Improved

downtownpony

only combined with options "AccelMethod" "exa" and "MigrationHeuristic" "greedy" in xorg.conf . Completely useless without it (maybe even worse)! The performance of many effects is unmistakenly better than with intrepid. 6 hours of frustration finally work out! (Kubuntu/2.6.28-11)
