A Long time Linux / KDE user and new user of KDE Neon, using 5.13, and so far am very happy with it.
Except:
I have a desktop with dual monitors, identical monitors except one has HDMI and the other doesn't

I set the monitors the way I want them, left and right and nominate the DVI connected monitor as Primary as it is on the left.

Every single time I boot the monitor settings have swapped the two monitors over, so the main monitor is the HDMI monitor on the right.

Also the ( I presume) first run monitor set up app pops up on the screen every time. Which I ignore and close (I did try it once and it turned my screen into gibberish) and return to display and monitor in settings to change them back to the way I want them. These settings simply do not retain the settings I set when I reboot.

Any ideas how I can make the setting a little more permanent. Recently came from Mint 18.3 (bailed with no KDE in 19) and previously a long time user of openSUSE and have never had this issue before, with the same desktop and monitors.

I have the same problem and the solution is to edit the xsetup file on / usr / share / sddm / scripts.
After each update sddm, the xsetup file must be manually edited, save the copy of the file to / Document

Code: Select all

#!/bin/sh
# Xsetup - run as root before the login dialog appears

mode="$(xrandr -q|/bin/grep -A1 "DVI-1 connected"| tail -1 |awk '{ print $1 }')"
if [ -n "$mode" ]; then
  xrandr --output HDMI-0 --off
  xrandr --output DVI-1 --primary --mode 1920x1080
fi

if [ -e /sbin/prime-offload ]; then
    echo running NVIDIA Prime setup /sbin/prime-offload
    /sbin/prime-offload
fi


Thanks for the reply.
I note the line
'echo running NVIDIA Prime setup /sbin/prime-offload

I have an AMD card and do not use NvIDIA drivers.

This is the script for the AMD GPU, it can be like this. I use a free radeon driver and this script.

Code: Select all

#!/bin/sh
# Xsetup - run as root before the login dialog appears

mode="$(xrandr -q|/bin/grep -A1 "DVI-1 connected"| tail -1 |awk '{ print $1 }')"
if [ -n "$mode" ]; then
  xrandr --output HDMI-0 --off
  xrandr --output DVI-1 --primary --mode 1920x1080
fi

Thanks, I'll give it a go.
