I am currently trying to run Stadia 4K gameplay in Ubuntu 20.04, which demands VP9 hardware accelerated decoding.

So far, I've tried both Brave and Chromium with hardware acceleration enabled, and I tried this tutorial: How To Enable Hardware Acceleration In Chromium On Ubuntu Or Linux Mint for installing a VA-API patched PPA build enabling hardware acceleration in Ubuntu, without success.

My current system configuration is:

Computer: Dell Latitude 5490
Distro: Ubuntu 20.04 LTS
CPU: Intel i7-8650U (4.2 GHz)
GPU: Nvidia GeForce MX130
GPU: Intel UHD Graphics 620
Graphics driver: nvidia-driver-440

Apparently, hardware acceleration does not work with Nvidia GPUs, but should work with Intel integrated GPU. However, selecting Intel GPU in Nvidia X Server settings, does not make hardware acceleration work as it should. It also made my system very slow and choppy when I use an external monitor.

How can I set up hardware acceleration correctly?

Output from running vdpauinfo returns the following:

display: :1   screen: 0
GPU at BusId 0x3 doesn't have a supported video decoder
Error creating VDPAU device: 1

The steps I took to run Stadia 4K gameplay in Ubuntu 20 in Chrome (maybe it works in Chromium too):

  1. Install the latest video card driver. For the NVIDIA cards, go to "Software & Updates" => "Additional Drivers" tab => choose the latest driver. Probably it's the same for Radeon.
  2. Install Stadia+ Chrome addon.
  3. Restart the browser.
  4. Before opening any games in Stadia, press SHIFT+TAB, a panel will appear on the right side, choose VP9 and 4k.

    Easy as that. =) I can confirm this works in Brave as well. Does this force hardware acceleration though? – Pål Bjartan Jul 20 '20 at 08:11

    This does nothing for hardware decoding. – alvarlagerlof Nov 08 '20 at 16:56
  • This actually explains how to enable hardware accelerated video decoding in Chromium-based browsers: https://www.linuxuprising.com/2021/01/how-to-enable-hardware-accelerated.html – Logix Jan 28 '21 at 12:36
