configuration gets messeed up when system is idle or monitor turned off

[kalimerox]

Hi there, I have 2 monitors running on my system. Whenever the system goes idle or i switch off one of the monitors the configurations gets messed up and i need to re configure it in the display manager. Is there a way to fix these settings? I have a 4k dell monitor and a hd lg working with a amd graphics card. Thank you!!

EDIT:
I m not sure if i posted this to the right section, if not feel free to move the thread...

Try using this command when the problem happens:

Code: Select all

xrandr --output DisplayPort-1 --mode 3840x2160 --primary --rate 60 --pos 1920x0 --output HDMI-A-0 --mode 1920x1080 --rate 60 --pos 0x0

If that works, then create a desktop launcher by right clicking on the desktop and selecting Create Launcher. Type a Name, such as xrandr. For the Command, add the xrandr line above. Right click on the launcher and select Properties > Permissions. Mark the checkbox next to Allow this file to run as a program.
