[DragonFlyBSD - Bug #2742] Switching back to laptop display using xrandr doesn't work

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2742 has been updated by profmakx.


Turns out that if the laptop lid was closed on switchback, the x-server crashed. This problem went away with the recent i915 update.

On my laptop, if I switched to my dock connected setup like this:

	xrandr --output HDMI2 --auto
	xrandr --output LVDS1 --off 
	xrandr --output HDMI3 --off
	xrandr --output VGA1  --auto --right-of HDMI2

trying to switch it back to LVDS1 like so

	xrandr --output VGA1 --off
	xrandr --output HDMI2 --off
	xrandr --output HDMI3 --off
	xrandr --output --LVDS1 --auto --primary

yields black screens all round, the computer is not accessible.
