my display is stuck at 1920x1089 (16:9) and my Toshiba TV is called "Unknown Display" I use Nvidia Drivers

Do You mean with ''Upgraded too new kernel'' that you have installed a newer Kernel or that you have the Problems after a normal Kernel-Update?

I used mainline kernels and installed the latest kernel (6.9.3)

the native kernel was slow and I couldn't use NVK

So i updated it too the latest kernel

Thanks for the swift answer too my problem guys :skull::skull::skull::skull::skull::skull::skull::skull::skull:

So, the 6.9.3 Kernel doesn't work for You, yes? Then You should try an older Kernel. You could try it with the 6.8 Kernel what Ubuntu 24 LTS uses.

Nvidia drivers, like Wifi Drivers, will rely on DKMS to probe the kernel module...

when I booted on the stock kernel with zorin 17.1 too uninstall 6.9.3
the problem has now spread too that now
I can't adjust my aspect ratio, my display is listed as unknown and theres no sound at all

I then installed and rebooted into 6.8
and I'm still having this issue

I have no clue what that even means

listen I'm sorry for sounding like a freaking Karen here. But I really want a solution too my problem quick as possible

DKMS is Dynamic Kernel Module Support.
If a user changes their kernel when the Nvidia Driver is probed by the previous kernel, then the driver will stop functioning because the kernel changed.
By using DKMS, you can enable dynamic support, so that if you change your kernel, the drivers will probe to the New Kernel.

Open terminal and copy and paste each line, one at a time. If you get an error, stop and relay it here.
sudo apt remove --purge '^nvidia-.*'

sudo apt clean && sudo apt autoremove

sudo apt install nvidia-550-dkms

I posted the command for the 550 driver assuming you are on a late model Nvidia card. If you are not, please advise what you have. You may have luck with

sudo apt install nvidia-545-dkms

On Z16.

Reboot and test.

All forum helpers are volunteers who assist users as their scheduling and time allows. We can all relate to having a persistent problem that needs solving - but patience is part of the setting.
Bumping the thread with multiple successive posts is not going to create a method that draws forum helpers online to see your issue.

I removed some of the errant posts. This forum also has language guidelines.


I had no clue about you all being volunteers. I'm sorry for the outburst I'll take responsibility for that.

also I'm using a Geforce RTX 4060 8GB on z17.1 not 16

i did both the 550 and 545 command and this message popped up
"Unable to locate package nvidia-550-dkms" and
"sudo apt install nvidia-545-dkms"

Please do not do both, since you can only have one installed Nvidia Driver at a time.

That is odd... I know 550 is in the repository.
You may need to launch Software & Updates and in the first tab, ensure all four of the Top Boxes are checked. Under Download from - set that to main server.

I am on 555, because I added a third party repository to upgrade to it. On the 4060, the 555 driver may be better for you.
You can try the same:

sudo add-apt-repository ppa:graphics-drivers/ppa

sudo apt update && sudo apt install nvidia-graphics-drivers-555

For future reference, you also can search the repository:

apt search nvidia-drivers


got the same message: "E: Unable to locate package nvidia-graphics-drivers-555"
