It sounds like a bug but I don't think I really get what is going on clearly.  Let me see if I have this right.

At the start, you have one monitor disabled, and one enabled, set at 1920x1080 with the command:

xrandr --output LVDS1 --off --output VGA1 --mode 1920x1080

Openbox is functioning correctly at this time.  You have maximized windows filling the screen.


Then, you run the command:

xrandr --output LVDS1 --off --output VGA1 --auto

which does not change the screen resolution, but maximized windows are shrunk immediately to 1280x800 (the size of the disabled screen).


Then, reconfiguring Openbox returns the maximized windows to their original size of 1920x1080.


Is this what you are experiencing, or is it slightly different?


And have you compiled Openbox yourself?  What version is it?  Etc..
