Can't nvidia driver properly Ubuntu 20 - RTX3060 properly

Hello, I tried multiple times to install nvidia driver for my new Glovary miniPC with no Luck.
I browsed many relevant issues and tried multiple solutions \ driver versions. Nothing worked.

Finally, I started with a fresh installation and just installed the latest driver, Same issue:
After installation without rebooting: nvidia-smi outputs “NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver”
After rebooting: nvidia-smi outputs “No devices were found”

In the “About” section of ubuntu, I see “llvmpipe (LLVM 12.0.0, 256 bits)” in graphics and not Nvidia.
The GPU is running properly in Windows.

Attached , nvidia-bug-report

I’d appreciate if anyone can help.

Thank you.

Hi @tekomorocarkyo, welcome to the NVIDIA developer forums.

This is relevant from the log:

Your system uses the Open Source nouveau driver instead of the NVIDIA driver.
Please make sure the driver is NOT used, the easiest way is to blacklist it.
You will find detailed information about blacklisting nouveau in the driver README file.

Thank you for the helpful reply.

I did blacklist the nouveau and reinstalled nvidia driver but I still could see the line “GPU is already bound to nouveau”. It looks like the system didn’t fully uninstall nouveau.

Anyway, I started with a fresh ubuntu and disabled nouveau before installing the driver, then installed the driver.

Now there is no “already bound to nouveau” line. Bur i still have the same issue

PLease read the README closely. It also includes complete installation instructions.
Something failed in your driver installation or the Ubuntu installation process installed another NVIDIA driver conflicting with your manual installation.

Also check whether you have secure boot enabled or not. Try disabling it first if you don’t necessarily need it.

-> Installing NVIDIA driver version 550.127.05.
-> Initramfs scan complete.
-> An alternate method of installing the NVIDIA driver was detected. (This is usually a package provided by your distributor.) A driver installed via that method may integrate better with your system than a driver installed by nvidia-installer.

Please review the message provided by the maintainer of this alternate installation method and decide how to proceed:

The NVIDIA driver provided by Ubuntu can be installed by launching the "Software & Updates" application, and by selecting the NVIDIA driver from the "Additional Drivers" tab.
