Phoronix: Mesa DRI3 Picks Up GLX_EXT_buffer_age Support

The Direct Rendering Infrastructure 3 code for Mesa has picked up support for the GLX_EXT_buffer_age extension...

Because of a bug in the way buffer_age has been used in the past (it worked with nvidia because their driver was broken; they fixed it and then we noticed that it was broken and fixed it as well). But that patch is in the clutter-1.16 branch and already in Fedora and Arch.

I understand, thank you.

Heads up:
Some relevant packages have been submitted to Arch AUR

But you can always use

compton --backend glx

with any non compositing window manager.

They have some nice information too:

thanks for explanation... lxde doesn't use any opengl compositor, so which compositor it uses?

AFAIK it does not use any.

This is not an OpenGL extension, its a GLX extension so none and no unless LXDE starts using a OpenGL based compositor.

Then why the clutter patch is needed?

what kind of opengl version concerns this implementation? Lubuntu (lxde) will take any advantage of this feature?

Nice!
Anyone knows what is needed for DRI3 to get used? Support in the various drivers?

Easy: check out the bug report.

This has nothing to do with GNOME. GNOME is using the buffer_age extension since 3.8.
The mesa patches got merged all that's missing to get it working (with any application / desktop i.e not only GNOME) is a ddx driver that enables DRI3.
