I have Chrome Version 65.0.3325.162 (Official Build) (64-bit) on 4.19.13-300.fc29.x86_64 with i915 graphics 00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake GT2 [HD Graphics 520] [8086:1916] (rev 07) (prog-if 00 [VGA controller]) And chrome://gpu says Video Decode: Unavailable And it points to this bug: https://bugs.chromium.org/p/chromium/issues/detail?id=137247 https://bugs.chromium.org/p/chromium/issues/detail?id=137247

  You need a VAAPI build of Chromium, it isn't on by default. Arch has a PKGBUILD in the repo: https://aur.archlinux.org/packages/chromium-vaapi/ https://aur.archlinux.org/packages/chromium-vaapi/ and I think there are builds for most popular distros out there nowadays. If you are on Arch or one of its family you can get a -bin version in the AUR or use ArchlinuxCN that builds it in their repo.

    The Chromium in Fedora's standard repo is built with it, and when I run it chrome://gpu does say video hardware acceleration is enabled. But at least with a handful of youtube videos, it doesn't matter, still uses 200%+ CPU, same as Chrome (no acceleration), laptop still gets hot and fans still run.

      Are you on wayland ? That only works for X. See the comments section of https://fedoramagazine.org/chromium-on-fedora-finally-gets-vaapi-support/ https://fedoramagazine.org/chromium-on-fedora-finally-gets-v...

I haven't been following that bug, but a couple of things. Did you ignore-blacklists ? If you do ignore-blacklists, it overrides some stuff, but not everything. Also, the about:gpu page is not entirely accurate (particularly after ignore-blacklists) from what I remember. I think you should play a video and go to chrome://media-internals to figure out which path it is using. There have also been patches to enable acceleration for intel, but not merged upstream. So if you got a patched version, or your distro did that for you, it could also work. Finally, it works on chromeOS, which also uses Intel hardware, but that's because google supports chromeOS.

You can get native GPU buffers via enabling zero copy rasterizer in flags and passing --enable-native-gpu-memory-buffers via chromium-flags or as an argument. They work on ChromeOS the same way they do on desktop Linux and I've been using them for months without issue.
