(nvidia-settings:39496): GLib-GObject-CRITICAL **: 09:43:42.816: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** Message: 09:43:42.914: PRIME: No offloading required. Abort
** Message: 09:43:42.914: PRIME: is it supported? no

enter image description here

I know I could switch between modes like this:

sudo prime-select nvidia # select nvidia gpu
sudo prime-select intel  # select intel gpu

But I would like to know why I can't see anymore PRIME profile tab in the nvidia-settings GUI application. I already tried different driver versions but each one of those just seems to bring me issues in the functioning (also hangs on boot sometimes). The right drivers for my GPU seems to be the 525 version.

EDIT - 1

I just tried @ThomZen answer. This is what was my nvidia-settings situation:

> apt policy nvidia-settings
nvidia-settings:
  Installed: (none)
  Candidate: 510.47.03-0ubuntu1
  Version table:
     510.47.03-0ubuntu1 500
        500 http://archive.ubuntu.com/ubuntu jammy/main amd64 Packages

And...

> nvidia-settings -v

nvidia-settings:  version 530.30.02

So I tried to remove my current version (530.30.02) and install the 510.47.03 version:

> sudo apt remove nvidia-settings
> sudo apt install nvidia-settings=510.47.03-0ubuntu1
> nvidia-settings -v

nvidia-settings:  version 510.47.03

But still PRIME profiles tab is missing in the GUI app: enter image description here

  • Same here, I have RTX 4050 Laptop. I was having screen frequncy issue first, then it's solved somehow and now I can't see any Prime tab and plus, when I put the laptop on sleep gpu doesn't go to sleep and its burning up on my backpack :\ – Ermanas Jan 06 '24 at 16:06

Hi to all with similar problem!
Same issue here on Ubuntu Studio 22.04.
Be aware: I found a solution but it is somewhat pointless as older drivers (that you are going to install) just activate the "Performance Mode" if you choose "on-demand". At least a little popup tells you that if you choose this option via X-Server GUI.

Nevertheless:
After installing CUDA drivers the option “Prime Profiles” was not available / not showing. The only solution that helped me was given in this discussion:

List all nvidia versions available in the repositories you have added with

apt policy nvidia-settings

Then install the one that was shipped with your ubuntu version with command

sudo apt install nvidia-settings=VERSION_FROM_UBUNTU

As I wrote it will bring back the option "on-demand" to your GUI but it is rather senseless.

Have nice day!
