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 (http://ubuntuforums.org/showthread.php?t=1930450) helps when X server does not support !!!!??? how it works?
plz explain what happens

thanks :)
