|Hi all. I get the following error when running startx in Xorg.0.log:
|(WW) Falling back to old probe method for modesetting
(EE) No devices detected.
Fatal server error:
(EE) no screens found(EE)
For context, I just installed a new graphics card in addition to my old graphics card, that is, I had a Radeon HD 7950 and I added in a AMD R5 240 (OEM) card which I plan to use my host card when passing the other 7950 through. However, currently, I cannot get the X server to start with the original HD 7950 connected to my screen like my original set up. I am running xorg-server-1.18.4 and I have xf86-video-ati-7.7.0 installed. The only major thing I changed in the kernel was that I added the firmware blobs for the R5 240 (Oland series) in addition to my firmware for the 7950. lspci -k and dmesg both reveal that both cards are recognized and are running under the radeon kernel driver.
Kernel config in case I messed up KMS or if something else is up: http://pastebin.com/chiy8kdn
Any help would be appreciated.
It seems that I had forgot to add a file in the xorg.conf.d which set up a monitor to each card. I needed:
for each card in my system.
