OS: Ubuntu 24.10 x86_64
Host: 21G2000AMX ThinkPad P14s Gen 5
Kernel: 6.11.0-19-generic
Resolution: 1920x1080

GPU: Intel Arc Graphics]
GPU: NVIDIA RTX 500 Ada Generation L (with nvidia driver 570)
Monitor: Lenovo G34w-10 (firmware LS1.4)

My Lenovo G34w-10 monitor supports several resolutions, including
3440x1440. I don't get any option to set this on my laptop.

I've had the same problems with Xorg and solved it by using xrandr to
add a custom resolution.

With Wayland & Mutter, I haven't found a solution.

I decoded the EDID for the display, 3440x1440 is listed.

  My Lenovo G34w-10 monitor supports several resolutions, including
  3440x1440. I don't get any option to set this on my laptop.
  
  I've had the same problems with Xorg and solved it by using xrandr to
  add a custom resolution.
  
  With Wayland & Mutter, I haven't found a solution.
  
  I decoded the EDID for the display, 3440x1440 is listed.
