I have recently purchased a Dell D430 with a WXGA matrix. At home I have a
docking station connected to a Samsung LCD screen connected via DVI (TMDS-1
output), which I use only when needed. This LCD has a native resolution
1280x1024 and xrandr reports that it doesn't support 1280x800, which is the
native resolution of the LVDS of my laptop.
The problem is, that when I start my machine, The resolution on the LVDS is
set to 1024x768, which is one of the resolutions supported by the external
flat panel. So the picture on LVDS is occupies just a part of a screen. I
can easily now switch to 1280x800 using xrandr, but I want do have it like
this by default.
Question: how to obtain it? How to tell X to set resolution which is native
to LVDS, not to any connected external output (possible are VGA and
TMDS-1).
In my xorg.conf I've defined such sections, which are used by X. How should
I change them?
Section "Monitor"
Identifier "LVDS"
VendorName "Built-in matrix"
Option "DPMS" "yes"
EndSection
Section "Monitor"
Identifier "TMDS-1"
VendorName "External monitor"
Option "DPMS" "yes"
Option "SameAs" "LVDS"
EndSection
Section "Monitor"
Identifier "VGA"
VendorName "External monitor"
Option "DPMS" "yes"
Option "SameAs" "LVDS"
EndSection
