[NVIDIA GPU] [Secure Boot] Cannot Set Monitor to 144Hz in KDE

Ask Fedora
, ,
1

Hi there,

I upgraded my system from Fedora 40 to Fedora 41 (and also upgraded KDE to KDE 6.2) today. After fighting with broken NVIDIA driver for over an hour (solved by installing nvidia-gpu-firmware), I found the options for monitor in KDE missing 4k@144Hz.

I’m using a Phillips monitor which supports 3840x2160@144Hz, and it works fine on my Windows, and on my previous Fedora 39/40, as long as the NVIDIA driver is properly installed for my 2080 Ti GPU (modded with 22GB VRAM).

I found this post on KDE forum and checked EDID of my monitor as:

$ edid-decode /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0/card0-DP-3/edid

Shockingly, there’s no 3840x2160@144Hz option!

Any suggestion for me to get my refresh rate back?

2

According to the EDID your monitor does not support that refresh rate.
Why do you think it does?

3

Added kde, nvidia

4

Because it does support on Windows and Fedora before upgrading…

You may also notice it says a maximum refresh rate as 144Hz but none of the listed options contains it.

5

Going to bed. Sorry for any delayed reply :smiling_face_with_three_hearts:

6

Did you install drivers on windows to support the screen?
If so whatever they do is not available on linux.

7

Eject the display port adapter and connect over HDMI. Same problem? If so, do you have the same problem with USB-C?

Yes → What nvidia driver version are you using & have you tried gnome 47? (serious).

8

#secure-boot添加

9

My problem solved and it turns out to relate to secure boot. To help (possible) others having the same problem, I will provide as much information as I can.

No. As far as I know, there’s no specific driver from the monitor vendor, just usual NVIDIA driver on Windows.

The HDMI cable is in a box at some corner and I just swapped DP port between my two monitors, and it didn’t help. Before I changing to other types of port, I found the current solution.

$ modinfo -F version nvidia
565.57.01

No.

At the beginning, I want to test why my previous Fedora works with 144Hz. I want to boot into Live CD of Fedora-KDE-Live-x86_64-40-1.14. Ventoy fails to boot because of secure boot, so I disable it in the BIOS. In the Live CD environment, there’s no 144Hz option (since no driver after all!), and I just tried to boot my Fedora 41 again, and the 144Hz option appears!

I start to suspect secure boot disabled NVIDIA driver in some way, and after switching it on and off, it proves. So, I followed roworu/nvidia-fedora-secureboot and … It works!

After the 144 option appears, I check the EDID info again.

You may notice that, /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0 becomes /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card1. Besides, at the end of the EDID info, there’s a Block 2, DisplayID Extension Block, which failed decoding as Block 2, Unknown EDID Extension Block 0x00 in previous try.

So, as a conclusion, I suspect secure boot completely blocked the NVIDIA driver, and before I handle it, each time I booted in a kernel without correct driver.

Well… Still so much to learn. I think maybe I should try to read something about secure boot (how can it prevent a driver) and MOK (what is it).

If you had secure boot enabled and did not previously perform the steps 5 - 8 in that guide you linked then it is almost certain that the nvidia drivers were blocked.

It is always easy to tell if the drivers are loaded with lsmod | grep nvidia. If that returns a list of modules then the drivers are loaded. If it returns nothing the drivers are not loaded.
