How to enable FreeSync on amdgpu?

[Zesko]

@MirceaKitsune

DISPLAY=:0 xrandr --output DisplayPort-0 --set "freesync" 1

I tried it out, 0 is the port my monitor is on as reported by xrandr. I am however met with an error about fonts and colors which I can’t quite understand.

X Error of failed request:  BadName (named color or font does not exist) 
  Major opcode of failed request:  140 (RANDR) 
  Minor opcode of failed request:  11 (RRQueryOutputProperty) 
  Serial number of failed request:  43 
  Current serial number in output stream:  43

I know that the key “freesync” does not exit in xrandr --properties, but there are other keys “TearFree”, “vrr_capable” , etc.

All keys are in xrandr --properties.

For example: DISPLAY=:0 xrandr --output DisplayPort-0 --set "TearFree" off

See the output of xrandr without error.

 xrandr --prop | grep TearFree 
        TearFree: off 
        TearFree: on 
        TearFree: on 
        TearFree: on

You copied the command line from HOW TO ENABLE AMD FREESYNC, but it is old.
