My system is a msi pcmate atx z97 mobo, 4790k, Gigabyte Windforce R9 390. The igpu is on open source (ubuntus default) drivers, as I have the 390 on proprietary drivers.
So far, only the monitor i run off of the 390 works. Funnily enough though, when I boot, it starts the UEFI on the 390, Gnome starts loading on the IGPU monitor, then it switches to the 390 monitor for the rest of time. Nothing in system is detecting the IGPU monitor, and its not the monitors themselves because i swap them around just fine. With just one monitor, I can run it off of either source perfectly fine.
In my motherboards UEFI, i have IGP multi display set up.
I cant just set up both monitors to my 390, because both these monitors are Vga, and to be honest I dont want to buy another displayport to Vga adapter.
Thanks to anybody who bothers
