           Summary: Plasma doesn't react well (on the fly) after connecting
                    a second monitor and running xrandr

            Status: UNCONFIRMED

My laptop has a 1024x768 LCD. I borrowed an additional LCD which has a resolution of 1680x1050. I connected this new LCD to my laptop. Before starting X I added "Virtual   2704 1050" to xorg.conf to make one big area for both LCDs in horizontal configuration. X started in clone mode and in this mode I logged into KDE 4. After that it tried to use the Monitors from System Setting to configure it so that the new LCD is positioned to the right of laptop's. As it didn't work from this tool I opened console and typed in the command "xrandr --output VGA-0 --right-of LVDS". After that the screens layout was fine but the Plasma desktop layout didn't react well to the change. For example the background plasmoid was only available to the very left part of this big 2704x1050 area (occupying 1680x1050). Same with thr Panel plasmoid. On the right monitor there was a big gray area without any background and panel. See the screenshot I will attach. I had to log out of KDE 4 and log back in for Plasma to set the desktop right (Panel on the larger LCD, two background plasmoids, one per LCD, see the second screenshot). I think that Plasma should set the second configuration on the fly after changing settings with xrandr and restart of KDE4 should not be needed.
