nvenc unavailable on Ubuntu 20.04

Post by molove »

Description of problem or question:

I have just upgraded my PC with a new mobo and cpu and done a fresh install of Ubuntu 20.04. When using Handbrake the option to use nvenc as an encode is not available to me, which it was on my previous system running Ubuntu 18.04 using the same Nvidia GTX1060 gfx card. Everything works as it should when booted into Windows, ie nvenc is available and encodes.
I'm quite new to Linux but all the drivers seem to be installed correctly and the gfx card is recognised by the system. The nvenc encoder lib seems to be installed.

The Activity Log lists my CPU but not my GPU, whereas under Windows both are listed.
I have searched for answers but have found none and I'm not sure what I may have done wrong, any help would be gratefully received.

Thanks, so installing HB from the official Ubuntu repositories was the problem. I installed the Flatpak versions and lo and behold nvenc worked.

Do you know when the PPA is going to be updated to Ubuntu Focal so I can install from there instead?

The Flatpak version of HandbrakeCLI won't import the presets from the Flatpak GUI version of Handbrake, which breaks my script unfortunately, unless someone out there has a script that will convert a preset JSON file into command line arguments for HandbrakeCLI.

I followed the build instructions in the docs and built it for myself, and everything is working as it should :D

The GUI Flatpak includes the CLI. To run it:

Code: Select all

flatpak run --command=HandBrakeCLI fr.handbrake.ghb <cli arguments>
That should solve your problem of using GUI presets

Oh, and FYI, you are the first person to report success using NVENC on linux that I know of. None of us have tested it :mrgreen:
I've never tested because I don't like installing proprietary drivers. I use Fedora and they do not provide packages. Since drivers must be EFI signed, not having official packages makes installation a PITA... and removing them is even harder :evil:

Would you care to share what packages were necessary to install to make it work so others can copy?

Erm, I've managed to get it working on Ubuntu 18.04 where I just installed the version from the PPA and iirc the Nvidia 430 drivers, it just worked in both GUI and CLI.
And on Ubuntu 20.04 using the Nvidia 440 drivers from the Ubuntu Repositories, there's a list of the installed packages in the OP, I don't think I installed anything extra. I just built Handbrake following the instructions in the docs, and it just worked.
I decided to get rid of my Ubuntu install and start again with Manjaro, I'll let you know how I get on with that.

Yes it's working under Manjaro too, I just installed the proprietary Nvidia 440 drivers using Manjaro Settings Manager/Hardware Configuration. I installed Handbrake using Add/Remove Software and handbrake-cli using the command line. Both are working. I did have to reboot after installing the drivers.
