I have a monitor that supports up to 3440x1440@165, but the maximum shown by wlr-randr is 3440x1440@100. I’m running hyprland Arch Linux which is my main system.
I tried booting with a live image of arcolinux-hyprland-v24 and garuda-hyprland but I have the same problem, both using proprietary drivers.
I did the same in ubuntu sway 23.10, garuda-hyprland and kde-neon, these times using nouveau drivers, and the correct refresh rate was shown.
Finally, I tried arcolinux-plasma-v24 using proprietary drivers. This booted an X11 session (all the previous were wayland sessions). I run xrandr and the monitor is again capped at 100hz.
So, the issue seems to be with proprietary drivers and uncorrelated to the graphic session.
I’m attaching the logs for the main system.
I’m sorry, I edited the comment with the correct one
Let me know if that’s anything else I can try.
I also tried in windows 11 and I can confirm it works @165hz
Driver bug. Please recheck with the latest 550.54.14 driver, if that also doesn’t work, mail the report to linux-bugs[at]nvidia.com, maybe you’ll get some attention.
