Public bug reported:
Binary package hint: xrandr
Hello,
I just wanted to use xrandr to set LVDS (laptop screen) and VGA (projector)
both to the preferred modes on my DELL E6400 machine:
xrandr --auto
But it doesn't work. The desktop window (on LVDS) was set to a smaller one, in
this case parts of the PDF file view (while full screen) run out of the
projector. And
xrandr --output LVDS --mode 1440x900 --output VGA --mode 1024x768 doesn't work
either.
xrandr --output LVDS --mode 1024x768 --output VGA --mode 1024x768
woks, but in this case the LVDS is not in the preferred mode.
Hereafter is the contents of /etc/X11/xorg.conf file:
Section "Device"
Identifier "Configured Video Device"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection
