When I add a monitor on the VGA port of my Lenovo X220, then I get the option to configure the additional display. All OK. But if I remove the display, then I'm in trouble. The display configuration interface detects (by graying out the removed monitor) that a display got removed, but the KDE4 desktop does not shrink back to the remaining displays. Plus, error messages or new windows appear on the non-existing display. The complete handling procedure is a mess. It kind of works, when running "xrandr --auto", but it does not necessarily reconfigures the same monitor plugged in again in the same way. Often I simply get a wrecked up duplicated display (both screens using their optimal resolution and not all stuff is displayed on every display). The same was found on a Kubuntu 12.04 KDE4 desktop with a bit less trouble when running xrandr (previous monitor configurations got restored properly). It does not get better when running krandrtray. Everything is working fine under GNOME. A monitor gets plugged in, the desktop extends automatically. If I configure it to sit on a certain side, then it gets every time properly reconfigured when (re)connected. This works properly with a couple of different monitors and exactly as I like to see it. I don't get bothered with pop-ups and do not need to accept/click/click-away anything. It simply works smoothly. Why it cannot act exactly the same on KDE4? The desktop is perfectly able to handle desktop expansion and reduction. Reproducible: Always Steps to Reproduce: 1. Start your laptop without a monitor connected. 2. Login to KDE4 3. Add a second display and enjoy the mess. 4. Remove the second display and it gets worse. 5. Try to get out of the mess (CTRL-ALT-BACKSPACE helps) Actual Results: The system is unusable with KDE4 in dynamic multi-display settings. Expected Results: Should seemlessly work like in GNOME. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
