    Compiz does not work because of blacklisting (I don't use it anyway).
    But I'm having significant overheating, CPU temp. is around 60-65C when idle (it was about 45-50C before). Any advice to fix this?
    Maybe you are seeing higher temperatures because of a bug in the driver causing the graphics hardware to poll constantly. Have you tried disabling compiz to see if it helps? Also try disabling UXA to see if it reduces temperature.

    My laptop runs idle at 34 degrees, and reaches no more than 60 degrees under full load. I opened it up and cleaned out a lot of dust a few days ago, which reduced the temperature significantly - but the driver changes didn't affect temperature for me.

    Well, if you're using the 2.6.30-rc2 kernel, you'll notice that the write-combining range is active when you first boot your computer (without any need for the script). When you restart X, however, the write-combining range disappears - in this case, you should use the script.

    Therefore, use the script only if you have restarted X.

    Yes. It works nice with official Jaunty kernel 2.6.28-11

    AppArmor fail?

    I used this guide for my Intel chip (GM965), and it's worked just fine. Some things I've noticed, though; the boot splash is gone -- I just get the standard verbose text up to the login screen. In that text, I'm also seeing
    Code:
    Loading AppArmor module... [fail]
    Is this just because the rc2 kernel doesn't have the restricted modules that the generic kernel has? Is it even really a problem?

    Thumbs down Re: HOWTO: Jaunty Intel Graphics Performance Guide

    lspci |grep VGA:

    00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)

    also just did - as I now know - not successfully the following:

    1. added ppa x to /etc/apt/apt.sources:
    #...
    deb http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu jaunty main
    deb-src http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu jaunty main

    ...
    as root:
    apt-get update ; apt-get dist-upgrade

    2. activated uxa in /etc/X11/xorg.conf: Don't use my BUS ID if not matched
    #...
    Section "Device"
    Identifier "Intel Corporation 82945G/GZ Integrated Graphics Controller"
    Driver "intel"
    Option "AccelMethod" "UXA"
    BusID "PCI:0:2:0"
    EndSection
    3. reboot

    ppracer now works fine and faster with uxa enabled than with 8.10, even with 1680x1050.
    With exa I just had estimated unusable 3fps...

    I need to say that after enabling compiz my x-server crashed
    so uxa still not stable using compiz with latest jaunty kernel
    and still some artifacts watching videos.
    I did not try and don't want to use rc-kernels...

    finally performace is acceptable after using rc2-kernel with exa and
    until now stable instead of using uxa.
    I used the settings from psyke83 except using exa instead of uxa.
    Maybe this helps someone having the same hardware as there seem to be different behaviour for different intel-cards.
    ppracer now works smoothly again.

    kind regards Peter

    Re: HOWTO: Jaunty Intel Graphics Performance Guide

    Is this intended to also fix a problem where Ubuntu is unable to boot into X at all? My computer always takes a long time to boot, then says it's going to go into low-graphics mode for the session. That always crashes, so I just drop into the command-line and run startx. That seems to work pretty decently, and video quality seems fine (haven't tried any games yet).

    I tried this fix, but it didn't really change much regarding the boot. Low-graphics mode stopped complaining about tiling (I assume that was only because of the line in the xorg that turns off tiling), and now it just says that it can't find the configuration info.

    Any help would be very much appreciated.

    Updating to the stable drivers and enabling UXA does help performance to a certain degree. However, it still won't fix the MTRR bug, and the official Jaunty kernel has a performance regression in the DRM kernel module compared to 2.6.30-rc2.

    Different strokes for different folks.

    Your experience reflects my own (no usplash and an error loading the AppArmor module). Unfortunately, the testing kernel doesn't include restricted modules. If you rely on any restricted drivers, revert to the official kernel (with the understanding that performance will drop).

    EDIT: After a bit of testing tiling "true" is a bad idea....
    RC2 gets the MTRR stuff right at boot time, so you don't need the scripts - unless you restart X without rebooting, in which case the script allows you to fix it without needing a complete reboot.

    Your tiling problems:
    https://bugs.launchpad.net/linux/+bug/349314
    ...will be fixed in an update release and it's already confirmed fixed in the test 2.6.28 kernel mentioned there, so don't post any "me-too" posts to that bug.

    It's also logged as a kernel bug upstream so eventually the Ubuntu-specific fixes they've come up with won't be needed.
