How to make display arrangement persistent in Ubuntu 17.10?

  • 772

I use Ubuntu 17.10 on Dell Latitude 3470 with specs:

CPU: Intel® Core™ i5-6200U CPU @ 2.30GHz × 4
GPU: Intel® HD Graphics 520 (Skylake GT2)
GNOME: 3.26.2
OS type: 64-bit

For my setup I use 2 external Dell 24" monitors, one is connected via HDMI and second is via VGA D-Sub. HDMI is numbered 2 and VGA is 3 in [Settings > Devices > Displays]. HDMI(2) monitor is on the left and VGA(3) is on the right. Every time I startup my laptop monitor sides get reset to VGA on the left and HDMI on the right, and I have to drag the monitor icons in Settings panel to their appropriate sides. I would like to make these setting persistent between boots. What I can do to achieve this?

I tried to run xrandr via ARandr but I got this error:

xrandr returned error code 1: xrandr configure crtc 0 failed

When I run xrandr --verbose the output is:

  1. Your output says you have Wayland, not X11, as the display system. I am pretty sure that is why xrandr is not cooperating.

    If you change to X11, I have a suggestion. For systems using X11 graphics, I use arandr, a small GUI program that is compatible with all X11 desktops. It allows you to arrange monitors and the save the configuration. Upon reconnect, the setting can be loaded.

    Little glitches like this caused Ubuntu to change default from Wayland to X11 in more recent Ubuntu.
