Version: unspecified (using KDE 4.7.2) OS: Linux When disconnecting an external monitory and selecting configure display I get a control center dialog with what looks like what I want - everything under VGA is greyed out. I select okay, but the desktop is still extended and the panel is still on the primary display which is the external display. Reproducible: Always Steps to Reproduce: - Connect external monitor - Select configure when the display change notification appears - Configure VGA as above LVDS, leave primary as "none" - Unplug the monitor, select configure when the display change notification appears - Click OK Actual Results: Panel is still not visible, desktop is still extended. xrandr reports: Screen 0: minimum 320 x 200, current 1280 x 1624, maximum 4096 x 4096 LVDS1 connected 1024x600+0+1024 (normal left inverted right x axis y axis) 222mm x 130mm 1024x600 60.0*+ 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected 1280x1024+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x1024 (0xda) 108.0MHz h: width 1280 start 1328 end 1440 total 1688 skew 0 clock 64.0KHz v: height 1024 start 1025 end 1028 total 1066 clock 60.0Hz Expected Results: VGA1 is completely disabled, desktop is resized to LVDS size and panel reappears.
I can confirm this bug. In my opinion, the easiest bug fix solving this problem is to enable the apply button in the display settings dialog after removing the physical connection to a display.
Confirmed. I've to run `xrandr --output VGA1 --off` everytime I disconnect the monitor.
Confirmed by other users.
