    OK, well good luck to you with that then as the open source driver will not do. I will be interested to see if you get it working.

    Is that enough for people here to be happy?

    I just built xserver 1.10 packages from the latest emgd - testing right now on xubuntu 12.04 (kernel 3.2.16)

    X loads ok and 3d acceleration/compositing works. (xbmc loaded now). 3d performance seems improved (could be my imagination though - but xbmc interface feels quicker)

    vaapi is not working however - with the vaQueryDisplayAttributes function failing.

    so now to try emgd 1.14 and xserver 1.9

    oh and the framebuffer was corrupted on leaving X still.

    Good news!!!

    I have just updraded oneiric+emgd to precise+psb and now I was testing performance, 2d.... It works, but sometimes i see films in tv, so I prefer Emgd drivers (vaapi + resolution).

    I was prepared to install emgd+xorg 1.9 with your indications and suddenly I see new version.

    I will be waiting your tests and If you need a tester I could help you (I have 1101ha)

    Thankssssssss!!!

    bad news...
    Sort of old news, llvmpipe would be the replacement. llvmpipe is working in both Ubuntu and Fedora, but is a little more polished in Fedora.

    On my gma500, llvmpipe works, but there is a bit of a performance hit, and cpu use spikes. llvmpipe is in rapid development and will almost certainly be better.

    Until then ...

    Both XFCE and KDE work well with the open source driver.

    Hey all,

    To make the brightness stuff a bit easier I wrote a little piece of C that you can compile, put in your path, chmod suid then run to change the brightness as a regular user. You can find it on my github. Be warned: this script only works if you can change your brightness by changing the value in /sys/class/backlight/psb-bl/brightness since that's what the code does.

    Read the readme for instructions and if you have any questions, comments or bugs, don't hesitate to post here or put them on github. Hope it's of use

    Cheers, Sakartu

    Also, you'll want to make sure you're not using the libva backend driver from the "Meego_Wayland" folder, since that one was built for a custom libva spin that had a lot of non-standard Wayland modifications rather than for a traditional X-based libva.
    Aha, that may well explain the problems with the new 1.14 driver mentioned above.

    I am using the 1.10 driver from the ppa (this is I believe the experimental driver that works with xorg 1.10) with oneric.

    This is with the stock libva drivers (1.0.12).

    For the 1.14 EMGD we should downgrade libva?

    I forget, what do you need the EMGD for ?
    Not sure about 3.4, but, as I wrote earlier, one that comes with 12.04 by default is slow even with XviD 720x304 video and flash video more than 240 even in window mode, plus "black screen after boot" problem not solved even after adding console=tty1.
    So for the moment I need EMGD to watch non-hd movies and I have nothing to see flash video in 360p or higher (don't tell me about addon that uses mplayer to watch flash video - it works not with all sites and it downloads full video before start playing it).

    Hmm, need to check this, last time I tried it quite long time ago, about 1-2 years ago.
    But anyway, I'd prefer to play flash video "natively", and also it was a bad surprise since with 3.0.9 kernel that I've built myself 360p was fine, but now it's not with 3.2.4.
