[Solved] X insists that I have two monitors (thinkpad x200)

I've just installed Arch linux and am mighty proud of that feat. However there is a problem with my monitor that I'm wondering if anybody would know how to fix.

My screen is working pretty decently colorwise and so forth, but X insists on loading the wrong resolution. My screen is natively 1280x800, but x configures it to be 1380x800, and all my programs pretends that I have yet another 100 pixel to the right side of the screen, even though my monitor oviously can't show them.

I tried to run "xrandr -q" to see what was going on. This is the result:

Xlib:  extension "Generic Event Extension" missing on display ":0.0".
Screen 0: minimum 320 x 200, current 1360 x 800, maximum 1360 x 1360
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm
   1280x800       60.0*+   50.0
   1024x768       60.0
   800x600        60.3     56.2
   640x480        59.9
HDMI-1 connected (normal left inverted right x axis y axis)
   1360x768       59.8
   1152x864       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9
HDMI-2 connected 1360x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1360x768       59.8*
   1152x864       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9

So it seems X sees another screen than the one I've been trying to configure in the xorg.conf file, and furthermore gets the resolution wrong. Does anybody know how I could potentially solve this problem?

SOLVED: I added the following lines to the xorg.conf file:

Section "Monitor"
       Identifier      "HDMI-1"
       Option          "Ignore" "True"
EndSection
Section "Monitor"
       Identifier      "HDMI-2"
       Option          "Ignore" "True"
EndSection

Try , as root in a konsole window, running:

X -configure :1

Then:

cp /etc/X11/xorg.conf /etc/X11/xorg.conf.original

...this will save your configuration as a safeguard !

Then:

mv /root/xorg.conf.new /etc/X11/xorg.conf

Reboot and see if you are now OK.

Thanks for your answer. It doesn't solve the problem though. The new xorg.conf file gives me a resolution of something around 800x600 and when I run "xrandr -q"  it says that it can't open display. furthermore plasma crashes on startup for some reason.

Try adding this to the Monitor section in xorg.conf:

Option "PreferredMode" "1280x800"

---

1000

Thanks for the help. I have solved the problem by adding

Section "Monitor"
       Identifier      "HDMI-1"
       Option          "Ignore" "True"
EndSection
Section "Monitor"
       Identifier      "HDMI-2"
       Option          "Ignore" "True"
EndSection

to xorg.conf

Now I just need wifi running consitently and I'm golden
