[SOLVED] Three monitors and Xorg

I'm trying to setup three monitors with X. My setup works with xrandr but I want something permanent.

Section "Monitor"
        Identifier "DP-0"
        Option "Primary" "true"
        Option "RightOf" "DP-2"
        Option "LeftOf" "DP-4"
EndSection

Section "Monitor"
        Identifier "DP-2"
        Option "LeftOf" "DP-0"
        Option "Rotate" "Left"
EndSection

Section "Monitor"
        Identifier "DP-4"
        Option "RightOf" "DP-0"
        Option "Rotate" "Right"
EndSection

I have 2 monitors in portrait on either side of one in the center, but with that config when I move the mouse from the right of the one in the middle it goes to the one on the left and then when i go to the right of the one left it jumps to the monitor all the way on the right instead of the middle. If I run

xrandr --output DP-2 --rotate left --left-of DP-0
xrandr --output DP-4 --rotate right --right-of DP-0

When I login things work as they are supposed to.
