To start xpra I did xpra start-desktop :20 --start=startplasma-x11 --resize-display=1920x1080 --video-encoders=nvenc

What am I missing? And, if you see something is missed in my config, please tell me.

`* nvenc : No module named 'xpra.codecs.nvidia.nvenc'

These builds do not support any nvidia codecs.

You will need to rebuild from source.

Another possibility would be to use nvenc via the more generic gstreamer encoder, but that's very much experimental.

Hello again.

Maybe @sbradnick can include the nvidia modules in his builds? Or should I opt for another distribution?. I'm really interested in getting max performance (I'm assuming that NVENC makes a great difference), and I'm at a point that can chose what distro install bare metal and vm.

[totaam]

NVENC does provide the best performance possible. Even the new gstreamer / libva option doesn't come close.

Including the NVidia modules in any build is quite difficult, and even then it may not always work if the drivers don't play nice with the version of CUDA used for building the modules. (though using the latest drivers usually works)

The official builds from xpra.org do have all modules enabled, but avoid Debian and Ubuntu as those distros are generally buggy and don't have proper support for Xdummy.

[friki67]

I've never been in the Fedora or Red Hat side of the street, I've used Debian/Ubuntu, Arch, Open Suse, so.... For a home server setup, with desktop, focused in containers and VMs using LXD, nothing professional, only enjoy selfhosting and learning... Would you recommend AlmaLinux?

[totaam]

Sure, AlmaLinux should work for that.

Thank you!
