GNOME Bugzilla – Bug 594119
No way to disable VGA output after it's been unplugged
Last modified: 2010-04-18 20:15:46 UTC
If I unplug an external display from my laptop, it disappears from the display preferences. The VGA port is still enabled, however, leaving me with a double-width desktop, half of which I can't access. The only way to disable the VGA output is to run 'xrandr --output VGA --off'. A button could be added that disables any unconnected but enabled outputs.
What happens if you select "Detect Monitors" after you unplug your monitor? That should solve the problem.
