I plugged a monitor into my laptop's VGA port. I ran xrandr --auto and got the mirrored screen. I found it a little distracting, so I turned off the LVDS: xrandr --output LVDS --off. So far, so good.
Now I want to unplug the monitor. How do I turn the laptop screen back on? I note that there is no --on option to match with --off. atom:~> xrandr --output LVDS --auto xrandr: Configure crtc 1 invalid time Am I looking at a bug, user error, missing feature, what?
