I'm trying to set up a dual monitor system on an newly installed ubuntu 14.04 system running kde 4.13.2. I have 2 monitors connected to the video card. The system defaults to a "mirrored" configuration. I can find no way to access a configuration utility that will let me set them up in side-by-side configuration. There used to be a button under "System Settings" -> "Display and Monitors" that allowed me to simply set this up. Now I can't find anyway to configure the monitors. Reproducible: Always
Please ask in a forum of your distribution for help. You need to install either kscreen or krandr (the latter being deprecated).
