Well, it seems that after 2 decades –or probably 15 years– of headaches setting up multiple monitors in Linux, things are finally turning around in the user’s favor, or rather, KDE users favor. In the beginning, there was X. X allowed –and still allows for– WIMP interaction on the Linux platform. Then came the evolution into Xorg, which eventually led to –just a few short years ago– zero configuration single monitor setup. As great a Linux is, some of us still to this day toil away at our xorg.conf trying to make our unique setup work, manually setting monitor coordinates and defining refresh rates. KScreen is the next evolution in multi-monitor setup in Linux, that is, if you’re a KDE user.
