I recently purchased a Lenovo Legion 5 15ACH6 laptop with Windows 10 home edition installed. It's CPU is AMD Ryzen 7 5800H with integrated Radeon Graphics and system memory of 16 GB and GPU is Nvidia GeForce RTX 3050 (video memory: 4 GB, GDDR6). In the BIOS menu, I had disabled the secure boot option with the Graphic Device set to default option of 'Dynamic graphics' (Other available option is 'Discrete Graphics'). I dual boot installed Ubuntu 20.04 on the system using the 'Safe Graphics' option provided in the GNU GRUB menu. I successfully managed to install Ubuntu, but it is not making use of the Nvidia Graphics card and is instead using the integrated Radeon graphics. I tried looking for the solution to my problem online, but could not find concrete answers. I am a bit confused as to how to proceed to rectify this issue and would like to receive some help regarding the same. Here are some of the commands I tried based on info available online:
$ dkms status
$
No output observed from the command above.
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make
sure that the latest NVIDIA driver is installed and running.
$ nvidia-settings; lspi -V | grep VGA
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
(nvidia-settings:16830): GLib-GObject-CRITICAL **: 14:19:56.983: g_object_unref:
assertion 'G_IS_OBJECT (object)' failed
** Message: 14:19:56.988: PRIME: No offloading required. Abort
** Message: 14:19:56.988: PRIME: is it supported? no
The above command also opens a blank dialogue box named 'NVIDIA X server settings'
