[SOLVED] Can't enable VRR/FreeSync on a FreeSync capable monitor.

Hey all,

I have a problem and I've been trying to fix it for a few days.

I've been using arch for a few days and everything's okay for now, except that I can't enable VRR.
I have a FreeSync capable main monitor but i can't enable VRR in plasma setting's mainly, the option just isn't there. It used to work in windows, I booted a Nobara live iso with plasma and it worked, the VRR toggle was there and it worked.

Note: I have an AMD RX 6700 XT but looks like the OS is not sure. I also have three displays.

I've tried a lot of things that I can't even remember but a saw somewhere the command "kscreen-doctor --outputs" which outputs this:

And apparently Arch detects my main monitor (DisplayPort-1) as Vrr incapable (look at the end of line 2 above).
I don't understand why as Nobara does detect it right and just works.

Does somebody know what could be wrong?
Thanks in advance!

X or wayland ?

Have you looked at https://wiki.archlinux.org/title/Variab … own_issues ?

Thanks Lone_Wolf!
For such a simple question.

I thought that I was using wayland as I installed it. But thanks to you I realized that I was using X because of my greeter.
So I installed sddm-git and now I am actually using wayland and everything works.

Thanks you so much!

Your greeter does typically not dictate your session display server.
For AMDGPU on X11 see https://wiki.archlinux.org/title/Variab … _on_AMDGPU

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
