Version: unspecified (using KDE 4.4.2) OS: Linux Under kde3.x the kicker was able to span two screens and the desktop acted as one single pane although windows were aware of the boundary between screens and would maximise and snap to this boundary. Under kde4 the panel is confined to one screen and each screen has a separate containment which makes using the dual screen setup as one screen impossible. I have tried removing the containment for the 2nd screen and enlarging the one for the 1st screen but kde overrides this. Reproducible: Always Steps to Reproduce: Start KDE4 on a dualhead system and it splits the two screens into separate containments Actual Results: Two separate containments one on each screen Expected Results: Should have one containment covering both screens and the windows should be aware of the boundary This is incredibly annoying!
Created attachment 50535 [details] layout example 2 top panels to change activities (auto hide) 1 middle panel to start apps (windows can overlap panel) bottom left (auto hide) bottom right (auto hide, open windows panel) Nothing to complain!
Precisely my point - I don't want numerous panels, I want one panel that spans the two screens and I want one desktop that spans the two screens so my desk top icons can make use of the area. And I still want the windows to be aware of the join in the middle. This worked perfectly in kde 3
I'm not a plasma developer, but I think this is a "WONTFIX" _by design_ Anyway, from my point of view, there are more benefits with the current implementation. I use two monitors too and my life is better with it :-) I can list some advantages. For example you can have two separated taskbar on the two monitors (very useful if you work with a lot of windows), it is more easy to place the panels when you use different screen resolutions and, generally speking, it is more tidy :-) Probably you could configure differently the X server in order to expose only one screen across the two monitors.
