Can someone who has one of the motherboards here
https://en.wikipedia.org/wiki/LGA_1155 which supports using Intel's
built-in GPU, and a dedicated GPU card like Nvidia, test?
That is, to see if using multiple video adapters simultaneously works
in Fedora 17? Please.
PS. My specs right now are:
MSI H67MA-E45 (B3) H67 mATX LGA1155 DDR3 PCI-E16 3PCI-E HDMI DVI Audio
GBLAN SATA3 Motherboard
Intel Core i3 2100 Dual Core Hyperthreading Processor LGA1155 3.1GHZ
Sandy Bridge 3MB
MSI GeForce GT 520 810MHZ 1024MB 1GB DDR3 PCI-E VGA DVI HDMI HDCP Video Card
