I’m helping my dad switch from Mint to Cachyos, and I’ve had some help from AI. I’d appreciate your help. System Specs: OS: CachyOS (Latest) Desktop Environment: KDE Plasma (Wayland) GPU: NVIDIA GeForce GTX 1080 Driver Version: 580.xx Monitor: 4K Display (TV) Connection: HDMI 2.0 Problem Description: I am unable to select 60Hz at 4K resolution; the system only offers 30Hz in the Display Settings. I am committed to using Wayland and do not want to switch to X11. What I’ve Checked/Tried: Verified I am on the 580 series driver branch. Verified nvidia-drm.modeset=1 is enabled. Tested the 580 drivers, but the UI still caps the refresh rate at 30Hz.
