set primary monitor for F13/F14

[unicron]

I installed F13 on my Thinkpad T410, and just upgraded to F14.
My desktop is KDE and I login from kdm.
I attach my TV via an HDMI cable (virtually a DP to HDMI cable).
In F13, kdm displays on internal monitor, and KDE desktop on TV after login.
In F14, both kdm and desktop display on TV.
I need the internal monitor to be the primary one, that is both kdm and desktop
display on the internal monitor. I have to run xrandr each time I login:

xrandr --output LVDS1 --primary

I add the following file to /etc/X11/xorg.conf.d

Section "Monitor"
    Identifier "Laptop LVDS Internal Display"
    Option "Position"  "0 0"
    Option "Primary" "on"
EndSection

Section "Monitor"
    Identifier "Toshiba TV"
    Option "RightOf" "Laptop LVDS Internal Display"
    Option "Primary" "off"
EndSection

Section "Device"
    Identifier "Intel Arrandale"
    Driver "intel"
    Option "monitor-LVDS1" "Laptop LVDS Internal Display"
    Option "monitor-HDMI1" "Toshiba TV"
EndSection

Section "Screen"
    Identifier    "Default Screen"
    Device        "Intel Arrandale"
    Monitor       "Laptop LVDS Internal Display"
    DefaultDepth  24
    SubSection "Display"
        Depth     24
        Modes     "1440x900" "1024x768" "800x600" "640x480"
    EndSubSection
EndSection

but it has no effect, Xorg.0.log says

(WW) intel(0): Option "Primary" is not used

Try updating your startup. If you only want to effect your login, you can add the command to .xprofile. If you want it to effect all profiles you can modify your desktop manager's startup files. For example, I have a dual monitor setup with my laptop docking station. xrandr does not detect the modes for the monitor connected via a VGA cable, but always selects that monitor as primary. So I have the following two lines in my /etc/gdm/Init/Default file:

xrandr --newmode "1280x1024_75.00" 138.75 1280 1368 1504 1728 1024 1027 1034 1072 -hsync +vsync
xrandr --addmode VGA1 "1280x1024_75.0"
xrandr --output HDMI3 --primary

I think this solution is better than using an X11 configuration file, as my display will correctly change back to my laptop display when I unplug from the docking station. I'm not sure if it would do that if I had configured these settings inside an X11 configuration file.

If you are using kde, the file to update is: /etc/kde4/kdm/Xsetup

Have you tried a .xprofile?
