Vgaswitcheroo is working in my HP now.

 

Madura, for the moment, as you said, I don't have so much knowledge neither time to install Arch. But, there are some news...

Vangel guided me for switching to discrete: I installed kernel 3.4, uninstall proprietary drivers, reboot and make the swith as this answare says: http://askubuntu.com/questions/142506/hybrid-graphics-on-ubuntu-12-04-switching-to-discrete

Surprise! It could change to discrette card. How do I know it? Now, the temp sensors says 80º, ha! I could see it in "cat /sys/kernel/debug/vgaswitcheroo/switch". And then, testing (3D Engine at fullscreen) with integrated and discrette, opensource and proprietary, I have this results:

Proprietary - Integrated: 17 - 24 fps, some flickering, sensor at 60º (I've used this)
OpenSource - Integrated: 8 fps, no flickering, sensor at 60º
OpenSource - Discrette: 20 - 30 fps, no flickering, *but the sensor says 80º!!* (I will have to invent something for this)

(I realized that I don't need 3.4 kernel, I uninstalled it because it doesn't recognize WiFi)

And, for the moment, with OpenSource drivers, PureData is turning the computer VERY VERY SLOW (everything in OS) and, obvious, 3D Engine at 2 - 6 fps. So, I can't use it for the moment. I don't know why and I just wrote to Pd mailing list.

Conclusion: for me, it's better using proprietary drivers with integrated card because of the temperature and the problem with PureData. Proprietary's works so much better than OpenSource... achieving the same result in the integrated as the discrete with opensource's.

Well, it doesn't change so much... but I'm more hopeful. For the first time, I could boot with discrete.

You may refer to https://wiki.archlinux.org/index.php/ATI_Catalyst, Catalyst does not support the newest Xorg servers. They do not update their drivers much(or someone can say Xorg is changing their driver interface too much) for what ever reason it won't work with newer Xorgs. And newer Ubuntu's use newer Xorgs that might be your problem but I am not exactly sure if you have time and knowledge I recon you try arch on a separate partition. It gives you more freedom to configure which version of what you's be using.

        but who asked for "seamless"? People just need a way to
        "switch" the cards on Linux *some how* without getting in to
        details. nVidia is now riding the Xorg bandwagon for
        optimus, soon they'll be presented with Wayland, if I'm not
        mistaken they've announced that they are not planning for
        Wayland.


    I bought a HP laptop a year and half ago. ATI hybrid with MUX and
    12 months hw part-only warranty. No official linux support.

    Month 0-6 - lots of unsuccessful fiddling and performance with
    ATI driver was the same as with Intel opensource. Not worth the
    money and effort.
    Month 7 - finally ATI driver works as supposed. I was able to
    switch with a logoff/logon and it worked at least 3 times faster
    then Intel in some tests I did. Unfortunately, gnome3-shell did
    not work with ATI driver. I dropped ATI driver and started to
    switch off the card during boot.
    Month 9 - later ATI driver versions supposedly fixed the problem
    with Gnome3, but it started telling me the card is not supported.
    Some month or so after, I was informed by ATI staff that MUX are
    not supported any more and never will be.

    This happened even before the basic hw part only warranty was out.
    HP does not care - it was never officially supported.
    ATI does not care - it was never officially supported.

    I agree with Linus' reaction and extend it warmly and happily
    towards HP and ATI, and of course Microsoft where the whole thing
    has it's roots.

    Hey, Vangel, I have a similar situation.

    One year ago, I bought Acer with notebook with Optimus. Then, I
    realized that it wasn't for Linux... I changed it for a Pavillion
    dv6 3160us, with 4250 and 5650 ATI cards... thinking PowerXpress
    DID work on Linux... I couldn't ever used the discrete card with
    Catalyst, nor OpenSource Drivers.

    The best configuration I was using was: Ubuntu 11.04, Catalyst
    11.6. There were some artifacts moving some windows, viewing video
    with hardware acceleration and using a 3D engine (Blender)... but
    the computer worked for my needs (look at it:
    http://vimeo.com/35154176, at minute 1:00 the digital puppet starts).

    Since I get the HP, I tested Catalyst 11.7, 11.8, 11.8, 11.10...
    Ubuntu 10.04, 10.11, 11.10... Mint... and in any of these software
    configs, couldn't use Blender (edit mode) because of visual
    errors. In Blender, the display had a ONE-EVENT-DELAY. This mean
    that, if I pressed a key, it display the change in the screen not
    at the moment, but the next time I press another key (or mouse
    click). All the events has that delay... yes, I know, it's very
    strange.

    I test vgaswitcheroo in Ubuntu 11.04... nothing. There's no way to
    use change to the discrete. And the open source drivers are really
    slower than the proprietarie's.

    Then, Ubuntu 12.04 arrived... and the last version of Catalyst.
    The discrete card still does not work, but: The hardware video
    acceleration is OK. Blender works OK. Only few artifacts on moving
    Blender windows... but now... I HAVE AUDIO PROBLEMS! I'm using
    Jack and have XRUNS (buffer under-or-overrun) that I didn't have
    before.

    (Vgaswitcheroo doesn't work in Ubuntu 12.04)

    I repeat... discrete card still does not work. I've used the 4250
    integrated card.... but spend so much money to have the 5650.

    Fuck you, ATI. Fuck you, HP.
