[SOLVED]Resolution stuck at 1024x768 after install nvidia dkms

Ride Garcher · 2024-04-28 21:16:54

In the resolution settings, the resolution appears to be locked at 1024x768 and there is no possibility to change it.
All this after installing the nvidia opensource driver package DKMS.
I had had the same problem by installing the proprietary nvidia drivers and had tinkered in the Xorg settings causing the system to need to be reset via a snapshot, but now I find myself with the same problem.

The resolution appears to be locked from the start. Even after selecting the kernel from grub the wording appears to be larger. A sign that (I'm guessing) perhaps the problem may not be related to the graphics servers?
I am currently using KDE with Xorg. The monitor obviously supports fullhd 1080p. And in fact the resolution was at 1920x1080 before I installed the drivers.
The video card is an RTX2070

EDIT.........Okay I just discovered something curious. If I start Arch using the standard kernel I don't have the resolution problem.
It occurred to me to try because when I broke the system I wasn't allowed to log in using the zen or hardened kernel, but I could log in using the standard kernel. that's how I was able to use time machine to reset Arch with a snapshot.

Anyway, another curiosity is that still even using the standard karnel the boot command line (the ones before entering the login manager) come out at a lower resolution. But when you get to the login screen everything is okay and the resolution is as it should be.

Do you have nvidia_drm.modeset=1 in your kernel boot line ?

pacman -Qs kernel
dkms status

EDIT.
@Lone_Wolf i've just added it:

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet"
GRUB_CMDLINE_LINUX="nvidia_drm.modeset=1"

Now the "cat /sys/module/nvidia_drm/parameters/modeset" returns "Y", but now if i try to start a session using Zen kernel it doesn't works. I have to reboot manualy and select the standard kernel

This means that we have not solved anything unfortunately. We are the same as before.

You only have linux-headers 6.8.7.arch1-2 but lack those for zen and hardened kernel, as a result

nvidia/550.76, 6.8.7-arch1-2, x86_64: installed

only the module for that kernel is built.
Install the missing header packages and in doubt rebuild the dkms modules.

Everything works!
Thanks a lot guys!
I thought installations of such indispensable items were automatic.
I will read the documentation better next time. it is my fault probably
