    Perhaps the nvidia driver doesn't load correctly. Could you open a terminal, enter lspci -nnk and look for your GPU in the list to check if the kernel driver in use says "nvidia" and/or "nvidia_drm"?

    [–] Kaiserschmarrn@feddit.org 1 points 1 month ago (1 children)

    I've an entry "3D controller" which mentions my GPU (GeForce MX150). There I have the following kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia.

    So I guess it should be fine, since both of the entries you mentioned are there.

    Ah, then you probably also got the Intel GPU and it's a hybrid configuration with the Nvidia being the "high performance GPU". If it doesn't say "kernel driver in use" (at least once you open some demanding application) saying "nvidia" it might uses nouveau, which would be wrong. However given the hybrid configuration your Intel GPU should be the one in control of the display, so no matter what Nvidia screws up it shouldn't affect your refresh rate settings… I think.

    Guess it would be best to head to the linuxmint.com forums and ask there. It's probably a small fix, like your intel driver not being fully aware of all display capabilities on this specific device (which you could set manually, I'd have to look up the exact xrandr command though - will also change in the future once Mint fully moves from X11 to Wayland).

    Yes, you're completely right! I've a little icon on my taskbar that indicates which GPU is being used (Intel or Nvidia).

    Thank you for your help! I very much appreciate it! I will create a post on the Linux Mint Forums as soon as I find the time. Right now, I'm rather swamped because of work and my Master Thesis and my laptop is currently working good enough.
