Re: Dropping fallback mode in 3.8

["Jasper St. Pierre" <jstpierre mecheye net>]

The hardware accelerated graphics API that the rest of the world has depended upon is OpenGL, minus Direct3D for obvious reasons. It's unfortunate, but if OpenGL isn't supported on these devices, a hardware accelerated desktop isn't going to be possible. I don't think it's worth it to write hardware acceleration code because the driver maintainers couldn't give us the API that everybody else has.

The issue should be fixed at the driver level, not at the GNOME level.

The unaccelerated driver is quite happy with 2D desktops but LLVMpipe and
the paths used by the Gnome bling and compositing seem to hit it a lot
harder.

That probably points to it being at least partly solvable by de-blinging
the Gnome3 desktop or optimising/changing how it renders. E for example
has multiple rendering back ends.
