Nvidia drivers Ubuntu 20.04

[deskopt]

Hello

I have an HP Omen ek0004ns with an Nvidia RTX 2060 mobile.

I recently installed Ubuntu 20.04.3 in a separate partition on my laptop.

I am having issues with the Nvidia drivers. I have installed the 460, 470 but I am met with the following error when rebooting.

"ucsi_acpi USBC000:00: PPM init failed (-110)"

I don't know what to do as I search on the internet and try different things but none have worked and they just seem to be for different systems that don't match mine.

Any recommendations on what I should do? I have kept the open source drivers in order to be able to boot properly but would be nice to have the Nvidia drivers up and running

These are the drivers that appear available on additional drivers software manager.

I have tried 470 (propietary, tested) and driver metapackage 460.

They weird thing is that with the nvidia drivers I can sometimes boot up. When I can't, It goes to a black screen and shows the error above.

Usually if I reboot from console it will not work. But if I reboot manually or turning the power fully of it may boot well.

Any help would be appreciated. If you need any extra information please let me know.

Thank you!

Start by purging any previous installations of the NVidia driver, in the terminal:

sudo apt-get remove --purge '^nvidia-.*'
sudo rm /etc/X11/xorg.conf (if present)

Reboot the system. Now, reinstall the Nvidia drivers
sudo apt-get install nvidia-driver-440

once installed now, change the conf file for NVidia:

sudo nano /usr/share/X11/xorg.conf.d/10-nvidia.conf

Edit the file with the following entries

Section "OutputClass"
Identifier "nvidia"
MatchDriver "nvidia-drm"
Driver "nvidia"
Option "AllowEmptyInitialConfiguration"
Option "PrimaryGPU" "yes"
ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
EndSection

Now Reboot - hopefully it will be fixed

That seemed to have worked even though it installed driver 460 for some reason.

Thank you very much for your prompt reply.
