    Question how i find my hybrid graphic is muxed or mux-less ? (to use vga_switcheroo)

    i bought hp dv3 2360ee notebook.
    it has hybrid graphic
    1: intel graphics media accelerator
    2: ati mobility radeon HD 4550

    is it mux-less ? can i use vga_switcheroo to enable discrete card?

    thanks

    It is almost certainly muxed. Mux-less setups showed up with the HD 6XXX series ATI hybrids.

    vga-switcheroo is your only option, and it is not guaranteed to work.

    ok , sorry
    i am using a program written by benjamim gois (VGAsw)
    when i press high performance lightdm do restart and the garphic card changes to : Gallium , so is it means that i'm doing right ?

    i know that in mux-less systems IGP connected to displays and descrete graphic only do rendering.

    i read in x.org that X server doesnt support hybrid graphics :
    "At the moment the X server does not support rendering and display from different cards so the discrete card can not be used with MUX-less systems at the moment."

    so the question is how this guide helps when X server does not support !!!!??? how it works?
    plz explain what happens

    thanks
