[openchrome] Games lag after upgrading to precise 12.04. X using software acceleration instead of hardware for 3D

[ExperiencedNoobie]

While the information was being collected to report this bug I got this message.:

Your system is providing 3D via software rendering rather than hardware rendering. This is a compatibility mode which should display 3D graphics properly but the performance may be very poor. If the problem you're reporting is related to graphics performance, your real question may be why X didn't use hardware acceleration for your system.

The problem might be related to the above message that appeared. Just after upgrading to 12.04 precise from 11.10, all fullscreen games lag badly. I am using xserver-xorg-video-openchrome drivers.

Here are the contents of my xorg.conf:

[Omer Akram (om26er)]

Not a Unity bug. You do not have H/W acceleration working.

[Daniel van Vugt (vanvugt)]

I suspect that if your system is running Unity with LLVMpipe then maybe we're re-exporting that to applications like games when we shouldn't. Please run:
    env | grep LIBGL
and let us know what the output is.

To confirm the root cause of the problem, please also:
    1. Install package mesa-utils
    2. Run: glxinfo | grep OpenGL
And paste the output into this bug.
