Hi everyone, as the title says, my laptop's internal display is stuck at 60Hz. I have two monitors, both with a 165Hz refresh rate, but here's the situation:
Fedora 42 KDE: I could change the refresh rate of the internal display, but not the resolution.
Fedora 43 KDE: I can change the resolution, but not the refresh rate!
My specs are:
KDE plasma 6.4.5 (wayland)
Kernel: 6.17.5
RAM: 32 gb
CPU: Ryzen 7 5800H
iGPU: AMD Radeon Vega (mesa drivers)
dGPU: NVIDIA Geforce RTX 3070 mobile (propietary drivers)
Disk 1: ssd 1 tb
Drive 2: 512 ssd gb
Well, if anyone has any ideas, I would greatly appreciate the suggestion. Thank you in advance.
Please post the output of inxi -Fzxx & dnf list --installed \*nvidia\* so we can see exactly what is installed and what nvidia drivers are in use.
Thank you very much for your response, well the output of the command "inxi -Fzxx" is:

Any ideas would be greatly appreciated.
What is the design refresh rate on the laptop screen?
The external screen on the nvidia gpu is at 165, but the internal screen is only at 60?
The only thought I have is something with the driver for that gpu or the kernel itself.
Was it different with the 6.17.4 kernel?
Please show us the output of lspci -nnk | grep -iA4 vga
The laptop's screen refresh rate is 165 Hz.
No, the same thing happened with the previous kernel.
The command output is:

One curious thing: when I disable the integrated GPU and only leave the dedicated one (Nvidia only), I can set both screens to 165Hz, which worked fine on Fedora 42 KDE. Could this be due to some kernel parameter I've set for Nvidia, like modeset=1 or fbdev=1, or NVreg_EnableGpuFirmware=0?
Maybe.
What is the output of cat /proc/cmdline?
Shows:
BOOT_IMAGE=(hd1,gpt2)/vmlinuz-6.17.5-300.fc43.x86_64 root=UUID=f87d47f3-74a2-4330-9675-f914e8bd3c52 ro rootflags=subvol=root rhgb quiet rd.driver.blacklist=nouveau,nova_core modprobe.blacklist=nouveau,nova_core nvidia-drm.modeset=1 nvidia-drm.fbdev=1 nvidia.NVreg_EnableGpuFirmware=0
Those cmdline options are probably not required.
You can test that by opening the grub menu and press e on the kernel being booted.
Then on the line that begins with linux= find and remove those options. Continue booting with âctrl-Xâ or âF10â as prompted.
If the display then works properly the options can be removed permanently with
sudo grubby --update-kernel=ALL --remove-args='nvidia-drm.modeset=1 nvidia-drm.fbdev=1 nvidia.NVreg_EnableGpuFirmware=0' followed by a reboot.

Okay, I removed the kernel parameters as you suggested. Nothing changed regarding the internal display; it's still at 60Hz. But... the performance in games with UE5 improved. I tested two titles for over 10 minutes each, and the difference was noticeable. Of course, I have my notes on installing the NVIDIA drivers, but they're from version 550, and many things have been fixed since then. I'll have to update those notes. Thanks for the input!
I have had this problem as well and somebody here in the forum gave me this command:
sudo rpm-ostree kargs --append="amdgpu.dcdebugmask=0x8000"
Now I know this is for an atomic version of Fedora but maybe somebody here can change the command into one suitable for a non atomic Fedora version.
It does work, at least here in my Lenovo Legion. One thing, after performing this command you have to do a reboot.
Success.

@pablore79 this might sound crazy and unrelated, but you could try removing amdgpu modules from the initramfs. I also have a laptop with a AMD iGPU and a Nvidia dGPU, and I realized that under some specific circumstances, amdgpu modules were not loaded properly and the internal display would either remain black or would be initialized at a fixed 60Hz refresh rate. It seems to be triggered by a kernel race condition during boot (amdgpu modules are big), removing the modules seem to fix this.
To try this, you just need to create a /etc/dracut.conf.d/omit-amd-drivers.conf file with:
omit_drivers+=" amdgpu "
and run sudo dracut -f to regenerate your current initrd. Reboot afterwards.
I hope this helps!
(BTW you should consider not writing every message as a code block, that would make them easier to read 
)

Hi, yes I tried it, even with the parameter âamdgpu.dcdebugmask=0x410â and none of them worked, thank you very much for the suggestion!
Hi! Iâll try it when I get home. Thank you so much for your idea; I have something new to try.
Regarding the text formatting⊠sorry! As you can see, Iâve already fixed it.

I just found the original thread from which I got the command.
The solution is in post 3:
sudo grubby --update-kernel=ALL --args="amdgpu.dcdebugmask=0x8000"

Yes, I know how to use âgrubbyâ; in fact, thatâs how I add boot parameters to GRUB for NVIDIA drivers, and I also remove them that way. Anyway, I really appreciate you taking the time to help.
Hi again, did you solve your problem already? If so, how did you do it? Iâm curious if, aside from what I wrote, there is another way to solve this.

Hi, I tried the kernel parameter you sent me, but it didnât work.
I also tried the suggestion from user AndrĂ© Costa, who proposed creating a file /etc/dracut.conf.d/omit-amd-drivers.conf and adding omit_drivers+=âamdgpuâ. While this works because it only activates the Nvidia GPU, the problem Iâm having is with virtual machines. I lose 3D acceleration with virt-manager, and other VM managers have other very annoying problems, even though virt-manager is the best in terms of performance. Iâll keep investigating and will let you know when I find a complete solution. Thanks a lot for your help.
Moving drivers out of initramfs is not the same as blacklisting them. AMD drivers will be loaded once the real root filesystem is active. This article might give some more context about the pros and cons of removing GPU drivers from initramfs (itâs not directly related to your case, but a good read anyway).

Hi everyone, I wanted to let you know that I implemented the solution suggested by user AndrĂ© Costa. It didnât solve the 60Hz issue on the laptopâs internal screen. Itâs true, it doesnât disable the iGPU, but it started causing unexpected restarts of KWin. This happened with Dolphin, Spotify, and Firefox, so unfortunately I had to revert everything to its previous state. However, I really appreciate the suggestions you all offered to help me figure out what the problem might be. Iâll keep trying other solutions I find, and as soon as I find one, Iâll let you know.
