I have two monitors on my desk in portrait orientation.
One is plugged in with a DVI cable and the other with a VGA (I don't have two DVI cables available) into my Gigabyte Radeon 7750 HD graphics card.
In Arch I installed xf86-video-ati
from the official repository.
When I boot the machine both monitors are recognized and cloned in landscape position.
I generated xorg.conf with Xorg --configure
and file is located at /etc/X11/xorg.conf
.
Inside of my xorg.conf at the end of all of the "ScreenX" sections I have added Option "RandRRotation" "True"
Now if I run xrandr --output DVI-1 --right-of VGA-0
the monitors will both be recognized as separate (not cloned displays anymore) and I am able to drag windows across the screens properly. However if I run xrandr --output DVI-1 --rotate right
nothing happens, the same for VGA-0. I have also tried xrandr -o 1
this turns off all of the screens until I run xrandr -o 0
which only turns one display (VGA-0) back on.
How can I get the screens to rotate to portrait?
Best Answer
I was able to rotate my screens by installing the proprietary AMD Catalyst drivers for my graphics card and editing
xorg.conf
.After installing the drivers I added the line
Virtual 4096 4096
to myxorg.conf
under all of theScreenX
sections. I was then able to usexrandr
properly.
