u/Technical-Drag-255

SOLVED

After updating to nvidia 595.71.05 my monitor got locked at 60Hz. Tried downgrading back to 580.119.02 but kept running into dependency hell the whole way through.

The main issue was lib32-nvidia-utils refusing to resolve — it kept pulling a mismatched version and blocking the entire transaction. Also got conflicts with linux-cachyos-nvidia-open and linux-cachyos-lts-nvidia-open during the downgrade.

Had to pacman -Rdd lib32-nvidia-utils first to force-remove it, then install all four packages together from cache via pacman -U. Said yes to removing the open kernel module packages during the conflict prompt.

A few questions:

Is 595.71.05 known to break refresh rates? Anyone else hit this?
Is removing linux-cachyos-nvidia-open / linux-cachyos-lts-nvidia-open in favour of nvidia-dkms fine long-term on CachyOS?
Any way to prevent this version mismatch issue in the future? Should I be pinning nvidia packages somewhere?

Running KDE Plasma on Wayland. Happy to share more details if needed.

edit: Found the root cause!! it amdgpu that was failing to discover on the Renoir iGPU, nvidia update was correlation, not cause. Adding amdgpu.discovery=0 in Linux line of GRUB config actually solved it
