hello,

As the below link, my Ubuntu 22.04 with nvidia-driver-525 is capped at 60 FPS on a 144hz screen.

The solution proposed in the link, I already have nvidia-drm.modeset=1

hwinfo --monitor

If you need more information beyond what is in the bug-report, let me know.

EDIT 22-12:
I also tried putting the variable __GL_SYNC_DISPLAY_DEVICE=eDP-1-1, but that didn’t work either.

I was having the exact same problem and i was struggling for weeks
I tried all the xrandr, modesetting, etc solutions i found on forums and none of them seemed to work.
What eventually worked for me was this:

  1. In your grub config file located at /etc/default/grub at the end of the line starting with GRUB_CMDLINE_LINUX_DEFAULT , add nouveau.modeset=0 (e.g mine looks like “quiet splash nouveau.modeset=0”)
  2. run “sudo update-grub” command
  3. In Additional drivers section of Software and updates, change your driver to a random nvidia driver and apply and after restarting, switch it back to nvidia-driver-525 (NOT THE OPEN KERNEL ONE!) and apply again (This version of nvidia driver seems to be using xorg as default)
  4. Now Login using a xorg session (NOT WAYLAND) and you’ll be good to go
    Remember that if you login using wayland even once after step 3, It will mess things up again and you’ll have to go through the whole process again and this solution only works with Xorg
    My understanding is that this is a bug for wayland display manager and I think they have mentioned it will be fixed in Gnome version 43
    Hope this helps

According to all logs, you don’t have any 144Hz display, the internal one only supports 60Hz, the external on HDMI 75Hz.

I`ll try!! Thanks!!!

Very strange!!!

When I was on windows 10 and then ubuntu 18 it always ran at 144Hz.

It is a Dell G3 15 3590

After upgrading to ubuntu 22, it remained only at 60Hz.

I wouldn’t know how that worked, according to the decoded EDID you posted, the panel is advertising itself as a 60Hz panel.

BTW, the internal display is driven by the intel gpu, not the nvidia.

You are right! I must have dreamed about it then! :D

I know that the doubt is not linked to nvidia, but can the intel and nvidia drivers coexist on the same machine?

Of course, they’re working in tandem.
