Monitor configuration not set with xorg.conf

Question

Hey,
I have a Lenovo Thinkpad x230 with Intel HD4000 Graphics in a Mini Dock Series 3 usb 3.0.
Connected to the Dock are both a 23' Workstation Monitor and a 32' TV. So with the internal Laptop Monitor there are 3 Screens available. The HD4000 is unfortunately able to drive only 2 of them at the same time.
My prefered setup would be to boot up with the 23' Monitor as primary Screen and the internal Display as second.
I can run this setup without problems if configuring it with xrandr but trying to boot with similar configuration in xorg, the internal Monitor ends up being the primary Display (and virtually left to the 23' instead of, on the right..).
My xorg.conf:
Section "Monitor"
Identifier "HDMI3"
Option "Primary" "true"
EndSection
Section "Monitor"
Identifier "LVDS1"
Option "RightOf" "HDMI3"
EndSection
Section "Monitor"
Identifier "HDMI2"
Option "Ignore" "true"
EndSection
In Xorg.0.log i can see the configuration is perfectly loaded but at the very end, a (wrong) configuration overrides it
**Correct**
[ 210.621] (II) intel(0): switch to mode [email protected] on pipe 0 using HDMI3, position (0, 0), rotation normal
[ 210.822] (II) intel(0): switch to mode [email protected] on pipe 1 using LVDS1, position (1920, 0), rotation
**Incorrect**
[ 211.486] (II) intel(0): switch to mode [email protected] on pipe 1 using LVDS1, position (0, 0), rotation normal
[ 211.486] (II) intel(0): switch to mode [email protected] on pipe 0 using HDMI3, position (1366, 0), rotation
As far as i could see the xorg should have the highest priority or am I wrong?
DM is Cinnamon.
Any help is welcome!
Thx

I think you are. I suspect cinnamon is overriding your setup - X starts with the settings you specified in xorg.conf, then cinnamon reads it's own settings and applies those. Try a simple window manager like openbox, if you'll get your xorg.conf setup, then you'll know it's indeed cinnamon messing things up.
