mv this file to either of the following dir’s (respective of distro in use):
/usr/share/X11/xorg.conf.d - Ubuntu
/etc/X11/xorg.conf.d - Fedora
verify that freesync is working:
cat ~/.local/share/xorg/Xorg.0.log | grep Variable
expected functional freesync output of the above cmd: “VariableRefresh: Enabled”
