All great features, but you should look at http://techbase.kde.org/Projects/Plasma/ScreenManagement http://aike.me/site/blog/20090407/multihead_in_kde_422 http://websvn.kde.org/trunk/KDE/kdebase/workspace/libs/kephal/ http://websvn.kde.org/trunk/playground/base/plasma/screenmanagement/ This was already the subject of a GSoC project in 2008, which was successful but stopped short of applying policies to restore previous configuration, doing KNotifications or events or providing UI to edit configurations. KRandR is a separate codebase which Lubos Lunak updated for 4.4 with some SUSE patches to launch an improved version of the KRandR KCM, and does not use Kephal. I feel the same itch as you do and have spent the last couple of days getting into the Kephal code - it's been hardly touched since 2008 and could do with a clean up, so I'll see how far I get with it over the weekend. Aaron, do you think there's another GSoC project in completing Kephal? > I already posted the idea on #plasma but had to leave before you could > answer so, it might feel familiar. > > I know though that there are problems with xrandr and some drivers, like > the NVidia driver.
