OC nVidia GPU in Gnome Wayland

Issues & Assistance Unsupported hardware | Dual boot
1

I have Wayland running under Garuda Gnome. I'm trying to OC the refresh rate on my monitor. I can do this using a custom EDID file under Xorg, but under Wayland, I can't seem to make it work.

I'm using an nVIdia GTX-1660 OC using the latest nVidia proprietary drivers v530.41.03.

From what I understand, you need to add a kernel boot parameter which I've added the following:

video=DP-1:1920x1080@75

After applying this via Garuda Boot Options and rebooting, when I try to change the refresh rate for DP-1, it only shows 60hz. Under Xorg, using a custom EDID, I can make make my monitors go to 75Hz. Just not under Wayland.

I'd also enable nvidia_drm.modeset=1 as well.

Is this a limitation of the nVidia drivers maybe? Any help would be appreciated.

in inxi 73

here 75

Maybe a wayland problem?

Yeah, not sure. I tried both 73 and 75 and neither one seems to take. It's not a big deal, but I can see a difference between 60fps and 75fps in games as that's a 25% increase.

Did you check

sudo nvidea-settings

videoinfo

sudo pacman -S hwinfo --needed
sudo hwinfo | grep -C3 "Resolution"

?

My monitors are rated at 60Hz but I can OC them to 75Hz. Under Windows, I use the nVidia control panel to add custom resolutions, specifying the refresh rate as 75Hz.

Under Xorg, I retrieved the EDID information from my monitors, then edited the files via an EDID editor to change the refresh from 60 to 75hz and then loaded those custom EDID files via my xorg.conf configuration via an "Option" line item in xorg.conf.

What I'm trying to do is OC the monitors past their specified refresh rate of 60Hz which I've done via Xorg and Windows. But for some reason, I can make it work with Wayland.

Here is the output for my display I'm trying to OC but as you can see, its specs state 60Hz is the max vertical refresh rate. Again, I'm OCing the refresh rate which works under Xorg and Windows:

I'm sure you searched already, but just in case, is this of any use?

Yeah, already tried that. Doesn't seem to work. My feeling is it's the nVidia drivers. I'm finding all sorts of issues with it lately, including not being able to set a custom fan curve. The default curve doesn't stop the GPU from overheating and freezing under Linux when playing games. I don't have this issue under Windows with the overheating.

In the end, I found that even with OCing my refresh rate, games have more frequent frame drops in games, causing stuttering, so I've gone back to 60Hz instead and games are a lot smoother with fewer frame drops as the GPU can render 60 fps pretty regularly.

Thanks for the tip even though I already tried that. I'm also finding that my nVidia GPU doesn't provide smoother gaming under Wayland. Yes, no screen tearing, but still it hitches here and there. So I'm back on Xorg and I just turn off my other monitors via a shell script I created to turn on and off various monitors.
