Comment 73 for bug 763052

I applied that patch to Ubuntu Trusty 3.13.0-38.65, and it gives a huge improvement. X no longer crashes on startup, and 3D acceleration works.

However I also get the glitchy noise a few times a second, except when showing a static image. It is all over the screen, and sometimes appears as triangles.

Running glxgears and Firefox at the same time also starts giving errors in the kernel log pretty quickly.
