Problem Description

Open Additional Drivers, install from there, not from Nvidia’s binaries. Or with sudo ubuntu-drivers install.

Now the problem: The last driver for your old Nvidia is the 470 branch that is deprecated. You may want to try a certain PPA (no guarantees).

Nouveau works well for me with wayland (in Ubuntu Desktop 22.04.5 LTS with resolution 3840*2160) with the same nvidia card as yours, so if you use xorg (x11), I suggest that you try wayland.

XDG_SESSION_TYPE=wayland

Edit: In order to check for future usage of nvidia GK106GL [Quadro K4000], I tested the recently released Ubuntu Desktop 26.04.1 LTS version live (booted from a USB pendrive). It uses wayland also when running live, and it can use the full resolution of my monitor, 3840*2160 (without any fixes, just the normal boot procedure).

I have no doubts nouveau can use the full, native, resolution in most cases. The problem seems to be enabling external video output in certain laptops.

The situation described by the OP is likely the result of the failed attempt to install the Nvidia binaries that blacklisted `nouveau`.

I wanted to move to nvidia because I was getting corrupt display too often and I thought I should try the other gpu driver as well.

I also don’t seem to be able to see the upgrade available yet:

$ sudo do-release-upgrade
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release
set Prompt=normal in /etc/update-manager/release-upgrades.

You can find the Ubuntu Desktop 26.04.1 LTS iso file at

and test it in your computer.

Sometimes it is a better idea to backup your personal files and then make a fresh installation of the new version instead of do-release-upgrade, because you get rid of old cruft, that may cause problems after the upgrade.

You may prefer the upgrade path, and you should get a release upgrade offer rather soon (because the first point release is available now).
