Monitor resolution in xorg conf applying to wrong device
I am wanting to use a Dell 3818uw monitor with a resolution of 3840x1600 on my Lenovo X1 Carbon (5th gen), running Kubuntu 18.10. It is connecting through a Lenovo USB-C dock and DisplayPort.
Looking at the output of xrandr I see the external monitor connected on device DP-1-1.
Probing the monitor for the resolution yields nothing, so I used cvt to get a Modeline:
Modeline "3840x1600-30.00" 246.25 3840 4040 4440 5040 1600 1603 1613 1630 -hsync +vsync
If I run the following script, it applies the mode line correctly and the display works as intended:
$ xrandr --newmode "3840x1600_30.00" 246.25 3840 4040 4440 5040 1600 1603 1613 1630 -hsync +vsync
$ xrandr --addmode DP-1-1 "3840x1600_30.00"
$ xrandr --output DP-1-1 --mode "3840x1600_30.00"
However, this doesn't persist it. To try and persist it, I put into /usr/share/X11/xorg.conf.d/10-monitor.conf
Section "Monitor"
Identifier "Monitor0"
Modeline "3840x1600-30.00" 246.25 3840 4040 4440 5040 1600 1603 1613 1630 -hsync +vsync
EndSection
Section "Screen"
Identifier "Screen0"
Device "DP-1-1"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "3840x1600-30.00"
EndSubSection
EndSection
When I restart Xorg (reboot or just restarting the display manager), it applies that resolution to the eDP-1 device, which is the laptop display, rather than the external monitor:
$ xrandr
Screen 0: minimum 320 x 200, current 2560 x 1440, maximum 8192 x 8192
eDP-1 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 309mm x 174mm
3840x1600-30.00 29.97 +
2560x1440 60.00*+ 59.99 59.99 59.96 59.95
[..]
And DP-1-1 remains untouched:
DP-1-1 connected (normal left inverted right x axis y axis)
2560x1440 59.95
1920x1600 59.95 DP-1-2 connected (normal left inverted right x axis y axis)
[..]
I am currently at a loss on how to have the settings correctly applied using the standard Xorg configuration files. Am I missing something obvious?
