    Also, don't forget to add "export GMA500_WORKAROUND=yes" to your ~/.bashrc

    small note:
    In the livecd i put this export in /etc/rc.local because the user was not available at iso building time.. (maybe was better in /etc/skel/.bashrc but i didn't think about it)

    What does the environment variable GMA500_WORKAROUND do? Mplayer specific improvement or necessary for other things than that?

    MPlayer, at least for now. The mplayer-vaapi patches have a slightly different behaviour for the GMA500 and for other vaapi compliant chipsets.

    This may be a rather simple and foolish question, but after updating the repos today apt-get now suggests me to upgrade the current kernel packages:

    Code:
    The following packages will be upgraded:
      linux-headers-2.6.32-24 linux-headers-2.6.32-24-generic
      linux-image-2.6.32-24-generic linux-libc-dev
    No big deal, but if I run 'uname -r', the output is (already) '2.6.32-24-generic'.

    Is this a new improved kernel with the same version number, or is it trying to overwrite the existing one and messing with my psb configuration? I'm confused.

    I've recently been testing the fan control feature in eee-control on my 1101HA (Atom Z530 + GMA500). Didn't know if it was working or not. Unlike Aurora Jupiter, eee-control does nothing to the FSB modes (performance, powersave etc), but it does indeed change the way the fan behaves.

    Disabling fan control results in having the fan stuck at a higher rpm for a longer duration. ~2600 rpm after a high CPU load even though the temp drops down from 60 C to 54 C in a couple of secs.

    With fan control enabled in eee-control, the fan speed drops quickly from 2350 rpm down to 1630 rpm (resulting in a CPU temperature of 55 C and a much less noisy computer). Disabling the fan control gives me a minimum fan speed of 1570 rpm but only when the CPU temp reaches ~51 C (which often takes a long time if the CPU load normally stays at 10-20% using Firefox, empathy etc).

    Overall, the eee-control seems to manage the fan on this notebook much better compared to not using it.

    Re: Guide to Get the Best Performace from the GMA 500

    Some updates (only for the brave!)



    Flash playback alternative:
    Credits go to jurekiteresa for pointing this out
    Tested with Youtube HD inside Firefox (still finding a way to apply the same stuff inside Chrome).. very smooth even full screen.

    We need:
    mplayer-vaapi
    gnome-mplayer with vaapi from:
    ppa:klich-lukasz/kleewho
    settings:
    http://lukaszklich.pl/wp-content/upl...api_output.png
    http://lukaszklich.pl/wp-content/upl...5/vaapi_va.png
    and
    gecko-mediaplayer

    In web browser curently only in Firefox I can play flash video even in high quality automaticaly.
    We need FlashVideoReplacer addons:
    http://flvideoreplacer-extension.blogspot.com/

    Also we need uninstall gxine (luca: not installed here)
    After completely installation all of above components we could play flash video without any problems from YouTube, Vimeo.,Blip.tv

    Compiz workaround:
    Credits go to knopper

    Install this temporary package which disable compiz conflict dependency (still not uploaded to ppa, we need some testing/feedback)

    and add n /etc/X11/xorg.conf DEVICE section.
    Option "ExaNoComposite" "true"
    Compiz seems to work well (perform like old releases).

    Thanks! I can confirm that compiz works!

    However, clicking the Firefox links (for flash improvements) results in "404 - Not found".

    Installed the .deb-package and added 'Option "ExaNoComposite" "true"' to /etc/X11/xorg.conf like you said. Also installed the missing 'compiz' meta-package (apt-get install compiz) and Compiz is finally working now! Definitely an improvement to the GMA500 performance (although small). But at least it provides transparency which is useful.

    Thanks for your time dedicated to this matter! Are you planning on releasing a new improved Ubuntu (poulsbo) .iso?

    A kernel security hole was found lately, seems like they are just rolling out fixed versions of the currently used kernel.
