I just finished my Gentoo minimal install and the first thing I wonder is why I get no picture. I did have signal on the live CD, so that was pretty odd. I plugged the monitor into the Intel HD Graphics HDMI output instead, and there was my picture.

There's just this issue, I have 3 monitors. I need the AMD drivers, so I go ahead and install the proprietary ones, because I have the best experience with those. In order to do that, I had to recompile the kernel with some settings off and on to enable the AMD KMS. I have no idea what it is, but it worked fine following this guide (for my Sapphire Radeon HD 7970).

I'm aiming to install XFCE 4, so I also had Xorg installed.

emerge xorg-server ati-drivers

I ran startx and got the picture I expected on the monitor plugged into the Intel HD port. Now I stopped the x-server again and ran aticonfig --initial and rebooted. I already know that aticonfig only updates xorg.conf and when I started x again it appeared on the correct monitor. The only thing bothering me now is that the CLI before starting x is STILL on the integrated graphics monitor. How do I get this sent to the dedicated graphics card as well?

Did you tell your BIOS to use the off-board graphics first? –  Ignacio Vazquez-Abrams May 18 '13 at 18:07
    
@Ignacio I have a feature to disable it completely, and I did that, but it doesn't seem to work. GRUB and the BIOS appears on my AMD monitors as well –  Time Sheep May 18 '13 at 18:25
    
The Linux console is managed by kernel proper - probably the on-board card gets initialized first and kernel decides to use that instead of the AMD card. Building the driver as a module and loading it only later might help. –  peterph May 20 '13 at 8:56
    
@peterph So you suggest I compile the Intel drivers as a module? Wouldn't that just render me unable to install the AMD drivers in the first place? Of course if I used the KMS thing it should work. Hmm. I'll give it a spin. –  Time Sheep May 21 '13 at 17:27
    
I don't understand why not having Intel drivers built in should prevent you from using AMD. And I'm not really sure it has anything to do with KMS. –  peterph May 21 '13 at 19:12
