My my my…I wish I had seen this thread sooner, as I have some first-hand experience with almost this exact situation and learned a few things during the torturously long debugging of it. I don’t know if this will be of any assistance, but here’s hoping…

First, I am pleased to inform you that reports of the demise of the vdpau-va-driver package have been grossly exaggerated, haha. It’s actually been reincarnated under a new developer not associated with the Mesa project and is now named nvidia-vaapi-driver. I wish that was the key to solving this whole affair, but I’m afraid there’s more. The code changes that were apparently necessary to solve my issue were only just released in the latest version, which sadly hasn’t been a priority for anyone on the Debian/Ubuntu/KDE packaging teams to push out to the repos.

That leaves it to you to compile the driver yourself, if you’re comfortable with doing that, or if not then I’m happy to share the packages I built of that latest version for everything from Jammy all the way up to Mantic, which I just uploaded to my PPA in case that was your preference. Naturally, you’ll also want to add the official NVIDIA apt repository to your /etc/apt/sources.list.d directory by placing a file in it ending in .list with deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/ / in it, then adding their signing key to /etc/apt/trusted.gpg.d with the command sudo apt-key --keyring /etc/apt/trusted.gpg.d/nvidia.gpg adv --keyserver keyserver.ubuntu.com --recv-keys EB693B3035CD5710E231E123A4B469963BF863CC. Polish it off with a sudo apt update and a sudo apt full-upgrade and if my experience is any guide, you’ll be NoMachine-ing all over God’s creation after a quick reboot. I’m sorry this advice comes so late and hopefully your problem is already long-solved, but perhaps in that case this’ll be of use to the next person to meet this fate. Best wishes to you.

P.S. The above directions were created with a baked-in assumption that you already have the apt-transport-https and apt-utils packages already installed on your system, as tends to be the case. If that happens not to be so, please install them with sudo apt install before following them. Toodles.
