Laggy External Display on Gnome + Nvidia + Wayland

cosmologist_piyush · 2024-09-16 12:57:39

Hello,
I am facing 2 small issues.
1. I have a 2K 165Hz Monitor, however, the max refresh rate option I get is 144Hz.
2. Although running at 144Hz the external display feels too laggy and janky.

Below are my relevant settings:

$  sudo pacman -Ss nvidia | grep installed
extra/egl-wayland 4:1.1.16-1 [installed]
extra/libvdpau 1.5-3 [installed]
extra/libxnvctrl 560.35.03-1 [installed]
extra/nvidia 560.35.03-5 [installed: 560.35.03-3]
extra/nvidia-settings 560.35.03-1 [installed]
extra/nvidia-utils 560.35.03-2 [installed]

As you can see, I am running version 560.35.03-2 of the Nvidia Driver

modeset-ing is done

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet nvidia_drm.modeset=1 nvidia_drm.fbdev=1 nvidia.NVreg_EnableGpuFirmware=0"

Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General and the outputs of

loginctl session-status
xrandr -q

My apologies for the late reply.
I don't think my Xorg log is valid primarily because I am on Wayland.
Also my Xorg.org files are not recent, not sure where can I find the latest one.

Neither is xrandr, but you want to test the behavior on an X11 session first, preferably not gnome but openbox, icewm or any other uncomposited session (ie. also not picom)
