How To Enable Glamor On Ubuntu?

Question

How do I enable Glamor mode which accelerates 2D graphics with OpenGL on Ubuntu?

See Choose acceleration method on Arch Linux wiki.

Answer 1

GLAMOR is an acceleration library merged into the X.Org Server 1.16 that provides 2D acceleration implemented over OpenGL so X.Org DDX drivers no longer need to implement 2D-specific code-paths. GLAMOR is designed to be universal amongst OpenGL / OpenGL ES supported hardware.

For Trusty the package to install is:

sudo apt-get install xserver-xorg-video-glamoregl

And you also have to manually edit /usr/share/X11/xorg.conf.d/glamoregl.conf to enable it.
