Description of the problem

1. I connect my external monitor at VGA-0 output and configure it with
xrandr --output VGA-0 --mode 1024x768 --below LVDS

2. The command from (1) has no impact until I do a VT switch

3. After the VT switch the VGA-0 display is correctly configured. I just run
"xrandr" and the VGA-0 configuration goes lost again. Until I do a new VT
switch, VGA-0 displays a portion of LVDS.
