I have a ThinkPad W520 with a docking station, and 2 LCD's on the dock, and the ThinkPad LCD.

I have all 3 monitors working but not in the correct "order".

Currently the TP LCD is in the middle, and the 2 DS LCD's are on either side.

X thinks it's TP LCD, DS LCD1, DS LCD2.

How can I get it to have the DS LCD's on either side of the TP LCD?

/etc/X11/xorg.conf:

I answered to your question twice, but now I found what is the problem here :)

in this section it says that DisplayPort Screen 0 is the middle one, you can understand that because it follows with "RightOf" and "LeftOf" for the other screens you have :)

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "DisplayPort Screen 0" 0 0
    Screen      1  "DisplayPort Screen 1" RightOf "DisplayPort Screen 0"
    Screen         "Thinkpad Screen" LeftOf "DisplayPort Screen 0"
    Option         "Xinerama" "on"
EndSection

change them into this and you'll get what you want:

Section "ServerLayout"
        Identifier     "Layout0"
        Screen         "Thinkpad Screen" 0 0
        Screen      1  "DisplayPort Screen 1" RightOf "Thinkpad Screen"
        Screen      0  "DisplayPort Screen 0" LeftOf "Thinkpad Screen"
        Option         "Xinerama" "on"
    EndSection

Hi , this Nvidia Quadro are very tricky but I think they already work with x11-drv-nouveau if so , if you use open drives. You don't need set xorg.conf , you just need use xrandr command. In kde you got "quick display configuration" and can configure the monitors position without restart X

TBH, I've never checked how it looks like in xorg.conf; however, this can be easily done with nvidia-settings GUI tool: run it and in the screen configuration screen you can select the relative position of each screen relative to the "main" one. So, select TP LCD as the 'main' screen, and for each DS LCD select the relative position to be right and left side of the main screen respectively. Apply the changes to see if it is what you want, and finally save the changes.

nvidia-settings doesn't see the LCD on the Thinkpad.
