GPU acceleration on the Chromium Web browser

Edit /etc/chromium-browser/default like this:

CHROMIUM_FLAGS=" --use-gl=egl --ignore-gpu-blacklist --disable-accelerated-2d-canvas --num-raster-threads=2"

You can see much smoother HTML rendering. Try this link to test the Webgl on the ODROID. Webgl demo

Tip: When you exit the full-screen mode, the screens goes just black from time to time.
Press “Ctrl-Alt-F2” and “Ctrl-Alt-F7” as a workaround.
The black screen issue has been resolved with the Kernel update of 3.10.92 or higher.

If you use the latest Chromium Ver 43 or higher, the hardware acceleration doesn't work if you don't enable it manually.
Enter this in the URL box of the Chromium.


And click “Show advanced settings…” in the bottom side.
Check “System - Use hardware acceleration when available” and restart the Chromium.

Kodi crashing when exit

The Kodi(xbmc) crashes when exit.

Workaround : Open a virtual terminal (ctrl-alt-F2) and kill it.

  • killall -9 kodi.bin

And return to desktop (ctrl-alt-F7)
