[SOLVED] Persistent :DISPLAY=:0 xrandr --output HDMI-A-0 --set..

I'm on Gnome X11 What is the most efficient method to make this command autostart and persistent.

DISPLAY=:0 xrandr --output HDMI-A-0 --set "vrr_capable" 1

Thank you in advance.

F.Y.I

Re: [SOLVED] Persistent :DISPLAY=:0 xrandr --output HDMI-A-0 --set..

Use a file like this:

Filename:

/etc/X11/xorg.conf.d/20-amdgpu.conf

Contents:

Section "OutputClass"
    Identifier "my amdgpu settings"
    MatchDriver "amdgpu"
    Option "TearFree" "no"
    Option "VariableRefresh" "yes"
EndSection

Thanks for advice. 
After searching through wiki, I consider use ~/.xprofile. It seems not complicated for me.
