Correct.

Actually I explained incorrectly. The first command works correctly as
I noted. Lets assume that then I go back to using only LVDS1 (my
internal LCD screen) and disable the external output.

If I do
xrandr --output LVDS1 --auto --output VGA1 --auto

The screen gets mirrored on both monitors, although maximized windows
will only cover 1280x800 of the external monitor. I guess this is
expected, since its being mirrored although at different resolutions,
so definitely not a bug in this case.

However, if after the command above I do
xrandr --output LVDS1 --off --output VGA1 --auto

Openbox still thinks that my internal monitor is on, and maximized
windows will only cover 1280x800 of the external screen. If I click
and drag the window title, it suddenly grows to fill the whole screen.

Its 3.4.11.1 from Debian testing.
