14.04 - Force Enable Hardware Acceleration in Firefox - Ask Ubuntu - Le Hollandais Volant
samedi 22 août 2015 à 18:37http://askubuntu.com/questions/491750/force-enable-hardware-acceleration-in-firefox
1). Check if Hardware acceleration is actually enabled in Firefox by visiting about:support looking for "GPU Accelerated Windows 1/1 OpenGL (OMTC)" under graphics. If this shows 1/1 you can stop right here, you not need this tweak. But if it shows 0/1 you can force it on.
2). Open about:config in Firefox (url bar)
3). Set layers.acceleration.force-enabled and layers.offmainthreadcomposition.enabled to true
4). Run sudo bash -c "echo export MOZ_USE_OMTC=1 >> /etc/X11/Xsession.d/90environment" to set the enviorment variable globally for X.
5). Reboot and check about:support for "GPU Accelerated Windows 1/1 ..."
