Hello,
I just installed zorin-os 17 Pro on my new PC.
Unfortunately I can't install a "good" driver for my nvidia Geforce RTX 4070 Ti Super. Is that, because its a new GPU?
Can you please launch a terminal and run
sudo apt install nvidia-driver-545
I use the xswat updates for mesa and other packages:
sudo add-apt-repository ppa:ubuntu-x-swat/updates
sudo apt update && sudo apt full-upgrade
Hi. Thanks for your help, but my card seems to need the driver 550 (545 seems to cause some issues)
Is there some way to get it?
This one shows error, when I try to install it.
Yes, you can use
sudo apt install nvidia-driver-550
Hi. The package seems to be unavailable.
Is there a way to find out, when it will be available?
You may just need the source repository:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update && sudo apt install nvidia-driver-550
Ok, thanks. Now I got the new driver. But I still have some issues
It is identified everywhere else, so that is most likely just an issue with Jockey (Jockey is the Additional Drivers Application).
You may need Mesa and other updates. Please add the xswat repository and then run your upgrades:
sudo add-apt-repository ppa:ubuntu-x-swat/updates
sudo apt update && sudo apt full-upgrade
Are you connected using HDMI, DP or something else? Or is this a notebook computer?
Hi again. 
At the moment I use a HDMI cable, but I will add another monitor using a DP cable.
I found an error, maybe it could help:
builder04@Desktop-ZorinOS:~/Downloads$ sudo nvidia-settings
(nvidia-settings:33744): GLib-GObject-CRITICAL **: 12:12:00.797: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 12:12:01.192: PRIME: No offloading required. Abort
** Message: 12:12:01.192: PRIME: is it supported? no
Its a normal desktop PC. The problems are still the same.
Secureboot is disabled!
Do I need to uninstall the other virtualbox-driver?

This is an important distinction.
Virtualbox, even with hypervisor, does not support GPU pass through to the guest in V.B. You cannot access the physical GPU from within Virtualbox.
I know that. I'm not running VirtualBox. This is real hardware. But this driver shows up, if I run that command. That's why I was asking why I should need it. Sorry for the misunderstanding. 
Ah, I see. I do not believe that should relate, no.
I am running the 545 driver using kernel 6.6.5 on Zorin OS 16.3 with a 3060 Nvidia card.
Everything I look up shows the 4070 running fine upwards of 525 on upwards of Ubuntu 20.04.
Is your HDMI cable(s) connected to the Graphics Card port or the Motherboard port at the back of the PC?
Its connected to the graphics card.
The thing is, that its not a 4070. Its a 4070 ti super, which was released in January (brand new). So I think there could be an issue, because its an early product. Also I found out, that MSI-branded GPUs had a driver issue. But mine is a gigabyte...
This is entirely possible. You may need to stick to the absolute latest drivers Nvidia releases and the latest kernel. The 550 is the latest Beta version. I am on the 545 and it works much better than the 525 or 535, on my machine.
You can install the 6.6.5 kernel from this repository:
sudo add-apt-repository ppa:tuxinvader/jammy-mainline
sudo apt update
Hello again.
I found the issue. On my mainboard I had one PCIe 5.0-Port. I had a riser-cable installed to rotate the GPU by 90 degrees.
If I install it without the cable or in a PCIe 4.0 slot, it will work.
Thank you very mutch for your help, Aravisian!
