xrandr --output LVDS1 --off; xrandr --current; xrandr

This is the requested output. Note that this command sequence doesn't trigger
the problem, i.e. the LVDS output stays off.
See next attachment that was generated with a sleep between the commands.

Not sure this is related, but I got the following in dmesg (during login):
