I have tw 15.6 and installed both gnome and plasma with Wayland and X11.
I have a gsync monitor from 2018 (Asus Rog pg348q) and Nvidia gtx 1080 so it should support vrr on Gnome. I enabled the VRR option via dconf, yet after restarting, the variable refresh rate option does not show in Settings - Display
Does it only support newer monitors and gpus? Because gsync option works fine, though not in as many apps as on Windows
just to confirm, you are logged into a wayland session correct? I was also just reading, the monitor has to be displayport or hdmi 2.1 (some monitors, not all)
unfortunately gpu is 1080 gtx so it does not meet requirements for Wayland vrr. Instead I rely on Gsync VRR on X11, which oddly enough has the best compatibility only with Lxqt manager. Alll the other managers are picky regarding Gsync activation for the applications and emulators I am interested in.
