Arch Linux KDE not saving monitor settings [closed]

Question

I am trying to get 2 monitors setup.

I have Radeon HD 4800, using the open-source driver. 64bit. When i change the monitor settings in KDE it changes, but when i reboot: the monitors is going back to duplicated (screen settings have not been saved).

This is the settings i want:

How can i make the system automaticly use these settings at boot?

Answer 1

I solved it. Made a script 1920x2.sh in /etc/X11.

xrandr --output DVI-0 --auto --output DVI-1 --auto --right-of DVI-0

Added this script to Alt + F2: Autostart. Maybe not the best solution, but i works.

To try to troubleshoot this, launch KDE from the Linux console and check its error output. Also check the Xorg log (usually found on /var/log/xorg.0.log). You may need to generate a config file manually. You could also try running display settings as root.
