--- Comment #5 from Alex Deucher agd5f@yahoo.com 2011-10-04 17:01:26 PDT --- You have a muxless laptop which means the discrete card is not connected to any displays. You won't be able to use the discrete card until the xserver gets the ability to decouple rendering and display (i.e., rendering with one GPU, displaying with another). It's a huge amount of work and won't be supported any time some.
