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

    Luca, is there any way to make that s2ram workaround the default way to suspend? It works if I do it manually, but the system does the default suspend procedure when I close the lid or leave it unattended, and that kills X.

    BTW, I only get around 1000 in gxlgears on an 1101HA — is that allright, or does that mean I'm doing something wrong?

    Will this work? i.e. replace the contents of /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux with

    Code:
    #!/bin/sh
    /sbin/s2ram –force
    I'll try it if no one says anything. The comments in the linked thread suggest it will work on Lucid.

    That's what I'm talking about! A way to integrate the suspend work around. Whoo hoo!

    Check this out http://www.ubuntugeek.com/fix-for-su...r-laptops.html

    Steps:
    Open the terminal ang gain root priviledges, then:
    Code:
    cp /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux.bak
    cp /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux.bak
    nano /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux
          PASTE:
    #!/bin/sh
    /sbin/s2ram –force
    
    nano /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux
          PASTE:
    #!/bin/sh
    /sbin/s2disk
    By the way you always talked about s2ram and suspend, but uswsusp comes also with s2disk, which is the equivalent of hibernation and it's working quite well on my (gma500 powered...sigh!) asus 1101ha

    It seems to work on my 1101ha but it restart the session and close my programs.
    But if I give the command "sudo s2ram --force" on terminal it works good.
    What's wrong?

    On my 1101ha glxgears returns around 1300/5 fps with jupiter set on "maximum performance".
    A question:
    When i start the session with WIFI disabled, even if I try to enable it doesn't work. Have you got the same problem?

    I get around 500 fps glxgears on my archos 9 tablet. Using mesa/software i only get around 30 fps...

    It all depends on your CPU and at what speed it is running, the Archos has an atom 1.2 Ghz ...

    I've been doing mostly some investigation lately, there is a closed source library with API that Meegos driver is based on from Imagination Solutions (designers of the PowerVR chip).

    We have a couple of possibilities we can go to:

    1. We keep current implementation, we fix Xv and for the future (10.10 maybe?) hope our binary blob keeps working. No texture_from_pixmap support is ever possible this way. No compiz and whatelse that needs it...

    2. We use Imagination Solutions API and build a driver on top of that. Sure we allready have a huge piece of code from our current driver, i've been looking at it and most can stay, only the opengl chunk changes and rebuild some little parts (mostly Xv that's not working right now anyway). I even see some possibilities for improvement, mostly alpha-blending could be improved (end result might vary, I have no idea what the library does on silicon or in software, if they do it in software, the real speed improvement will probably be nil...).

    3. We go meego's driver all the way. Everything is closed source. I don't think this one will be the best unless Intel decides to open-source the xorg part, and if they do we receive a head-start for case 2

    I don't know how much difficult could be building a driver on top of their specs so my opinion maybe not so useful.
    Second solution sounds good and *seems* the most maintainable solution for future release..
    in the meanwhile i tried to build the current driver stack for 10.10 via PPA and everything build but no xpsb-glx (here is the build log).. maybe this is useful for your investigation.

    Can you check if you have libva.so.0 as a link to something ?

    This is the error in your build log:
    dpkg-shlibdeps: error: couldn't find library libva.so.0 needed by debian/xpsb-glx/usr/lib/va/drivers/psb_drv_video.so (ELF format: 'elf32-i386'; RPATH: '').

    In the mean time maybe it is best to fix the Xv bug in our current driver as rebuilding it to the API might take alot of time and work (maybe for ubuntu 10.10).
