Hey I’m new to the forum, new to Linux and a recent Windows convert. I signed up to hopefully get some help with my issue.
Problem:
I use a dual monitor setup, so the ‘switch display’ Meta+P shortcut from KDE daemon is really useful to me. The problem is it always resets my external monitors refresh rate to default 60hz when I want to always keep it at 144hz.
I’ve checked xorg’s log and each change the refresh rate is set to “auto” rather than what I specify in my nvidia.conf.
How to repeat:
Simply change display config with Meta+P
What’s expected:
For each monitor to select my correct refresh rate set in my nvidia.conf
What actually happens:
(See log) xorg loads 2560x1440 Auto mode rather than 144hz.
What I’ve tried to fix:
- Originally had my .conf in: /etc/X11/Xorg.conf but read FAQ that it needs instead to be /etc/X11/mhwd.d/nvidia.conf instead. Moving it here its still not being applied correctly.
- In KDE display manager, set resolution and apply.
What I suspect is the problem:
Either something is being done by KDE itself to override my .conf and switch my display to the default of 60hz, or my Xorg isn’t being read correctly.
A quick and dirty fix may be to edit what my default refresh rate is so it resets to 144hz instead of 60hz each time. But more preferably I’d like to figure out why my config doesn’t seem to be loading. Does anyone know how I can make 144hz the default refresh rate, or preferably how I can debug why my nvidia.conf isn’t being used on a display change?
