Comment 9 for bug 386907

Just noticed the following:
LVDS1 is disabled by GNOME according to the display settings set there.
VT-switching enables LVDS1 and shows the console. If I switch back to X, I
first have to manually enable LVDS1 (xrandr --output LVDS1 --auto) before I can
turn it off again (xrandr --output LVDS1 --off). After I've done that, LVDS1
isn't enabled anymore when I vt-switch and stays off, on console and X.

xrandr -q reports the following (before switching to vt1 the first time, while
LVDS1 displays the console although I switched back to X and after I manually
disabled it):
