Fdora 16 beta log me out random

[Pete Travis]

I don't think SELinux has any bearing on the driver's ability to properly
work with switchable graphics.  Suggesting the OP turn it off is akin to
suggesting a user run a segfaulting program as root.  It addresses a problem
that may not be relevant, and does so with complete overkill.

IIRC, Linux in general does not play nice with software switchable graphics.
Unless there is a physical mechanism to switch between GPUs, you may be
SOL.  I will offer the off-the-cuff suggestion of explicitly defining your
desired GPU and it's PCI bus id in xorg.conf.

Here's some reading, for your reference :
