(Tutorial) How to make high refresh rates work in Xorg
This concerns a multi monitor setup with different refresh rates (e. g. 1 with 60hz and 1 with 144hz).
The text below is part of the linked article. If you have both nvidia and picom installed, check both sections.
NVIDIA (propietary)
- Open
nvidia-settings - Go to 'X Server Display Configuration’
- In the bottom right, Click on ‘Advanced…’ if it says 'Advanced…'
- Make sure anything regarding ‘force composition pipeline’ is checked off
- Make sure you selected the highest refresh rates possible. You can either select it through the settings, configure it with
xrandror with your DEs Display Settings, is applicable
picom
- Make sure to start picom with
–no-vsync
Misc
If it still doesn’t work, try settings these environment variables:
<span style="color:#323232;">CLUTTER_DEFAULT_FPS=<your highest refresh rate>
</span><span style="color:#323232;">__GL_SYNC_DISPLAY_DEVICE=<your highest refresh rate display>
</span><span style="color:#323232;">__GL_SYNC_TO_VBLANK=0
</span>
Find the DISPLAY_DEVICE name with xrandr | grep connected
Add the text block above to /etc/environment (Tip: Use EDITOR=<your editor, if EDITOR is not set anywhere else> sudoedit instead of sudo nano or sudo vim)
-> sudoedit /etc/environment
