I have the XFX double-D HD 7970 3g GPU and back when I was on windows I had a 3 monitor and TV set-up. I used to use profiles to switch between a TV mode with XBMC, a Eyefinity mode with my 3 monitors as one giant one with bezel compensation, and an extended mode.
I want to be able to play my games in eyefinity mode (all three monitors as 1 giant one) in the display manager it claims that my desktop area is 5760*1080 but games playing in full-screen (left monitor) or windowed maximized it takes only one screen.
Steam recommends I update my driver to a newer one, which I tried to install I did it with --force command as it failed the first time which does not work, it installs it but breaks unity and I have to do a bit of work to revert back to the old driver and restart unity. as well as the driver did not work properly installing it that way.
I am currently using the fglrx-updates (propietry) driver [AMD] nee ATI: Tahiti XT [Radeon HD 7970]
How do I properly install a different driver from AMDs website?
How do I get a proper Eyefinity mode?
How do I enable profiles to switch between the 3?
