Want to use your Linux box to access website like:
- put any other cool website using html hardware acceleration here
But you are told your browser or operating system do not support hardware accelerated html5 features?
Is your graphic card correctly configured and you are sure the graphic acceleration works?
Then this post is for you.
You’ll find many website suggesting to execute chrome with options like:
Well.. do not do it. That’s the last resort if everything else suggested here fail..
Go on and enter your Google Chrome gpu page by writing this in the url box:
You may read something like:
Graphics Feature Status
- Canvas: Software only, hardware acceleration unavailable
- Compositing: Software only, hardware acceleration unavailable
- 3D CSS: Unavailable. Hardware acceleration unavailable
- CSS Animation: Software only, hardware acceleration unavailable
- WebGL: Unavailable. Hardware acceleration unavailable
- WebGL multisampling: Unavailable. Hardware acceleration unavailable
- Flash 3D: Unavailable. Hardware acceleration unavailable
- Flash Stage3D: Unavailable. Hardware acceleration unavailable
- Texture Sharing: Unavailable. Hardware acceleration unavailable
- Video Decode: Software only, hardware acceleration unavailable
- Video: Software only, hardware acceleration unavailable
You want to turn it into this:
Graphics Feature Status
- Canvas: Hardware accelerated
- Compositing: Hardware accelerated on all pages and threaded
- 3D CSS: Hardware accelerated
- CSS Animation: Accelerated and threaded
- WebGL: Hardware accelerated
- WebGL multisampling: Hardware accelerated
- Flash 3D: Hardware accelerated
- Flash Stage3D: Hardware accelerated
- Texture Sharing: Hardware accelerated
- Video Decode: Hardware accelerated
- Video: Hardware accelerated
Disclaimer: I’ve everything enabled but, depending on your graphic card something may not be available for you
Just open another tab on your Google Chrome (or Chromium) and write this in the url box:
You can experiment, but this is what I have (only the relevant options):
- [ON] Override software rendering list (probably the most important one if your hardware is blacklisted)
- [ON] GPU compositing on all pages
- [ON] Threaded compositing
- [OFF] Disable accelerated 2D canvas
- [OFF] Disable deferred 2D canvas
- [OFF] Disable accelerated CSS animations
- [ON] GPU Accelerated SVG Filters
- [OFF] Disable GPU VSync
- [OFF] Disable WebGL
- [ON] Smooth Scrolling
- (not related to graphic) [ON] Enable Encrypted Media Extensions on <video> elements
- [ON] Enable CSS Shaders
- (not related to graphic) [ON] Web Audio Input
HINT: this can be confusing, sometime you see “Disable WebGL” with a button below that say “Enable”, if you click “Enable” you… Disable WebGL, yes! :) you are ACTIVATING that flag and what that flag does is: “Disable WebGL”. That’s why so many options are OFF there.
Now that you know this you can go on experimenting yourself with the other options.
After modifying these options you should see a “Restart” / “Relaunch” button on the bottom, hit it to restart your browser and see the changes in effect (back to the chrome://gpu page to see if something changed)
I had to warn you, like chrome does, that messing with this flags is experimental and potentially dangerous: your browser may start to crash and things like that, it really depends on your hardware so fill free to experiment.
This has been done on Google Chrome version 23.0.1271.64 (Official Build 165188) on Debian Linux with an Intel i945 Graphic Card, but can work on any other setup (nVidia, AMD) as long as your graphic card driver is installed and well configured. Some graphic cards are know to cause issue or not support some of the feature above, up to you to experiment; if you try and want to drop your experience as a comment make sure to specify your graphic card, driver used and what works / didn’t work ;)
Hope this helped someone
