I have a machine that is running KDE on CentOS 7. For some reason, my screens are mirrored and KDE does not give me the option to have them extended.

I tried re-installing my driver (AMD card) and no luck. The thing is that it used to work, and ever since there was a power outage, I can no longer do so? Can anyone help?

xrandr

Examine the output to figure out what your left and right displays are called in xrandr, and then:

xrandr RIGHT_DISPLAY --right-of LEFT_DISPLAY
