[Tecnica] xorg e caratteristiche driver radeon per grafica ibrida

[Edoardo Giomi]

ciao a tutti,
gentilmente qualcuno saprebbe spiegarmi questa nota?

There are two versions of hybrd graphics: MUXed and MUX-less.  MUXed 
have a display MUX to switch the displays between the discrete and 
integrated cards.  MUXed systems can be switched using vgaswitcheroo.  
MUX-less do not have a display MUX and the displays are only connected 
to the integrated card.  On MUX-less systems, the discrete card is 
solely for rendering, not display.  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.  Most new laptops 
(2011+) are MUX-less.

Per caso significa che, in caso di muxless, la scheda discreta è destinata al momento a rimanere inutilizzata?
grazie in anticipo,

edoardo
