Basically i installed Kal 2.0 and i booted it up and it starts up with the display messages (or whatever verbose it goes through before booting into gui) showing on both screens then after it actually boots into the gui it will only display on the one graphics card. I have googled for the better half of two days and broken several installs hence the reason I'm finally sucking it up and asking for assistance. when i run lspci it shows that i have both graphics cards however when i go into the "settings" it only shows the one monitor. Also for further information both are running out of HDMI ports in the rear, also i have swapped the cards already around inside. It seems like the cards are automatically setup to run crossfire, however from what i have read linux doesn't support that. at any rate below are some of what i have for information.
