Bug Description

Binary package hint: compiz

We need a patch to force the FGLRX driver to go into direct rendering mode. The trick is to change the compiz program name before and after the GL driver is initialized.

This is a potential FFE request that we may choose to drop depending on the speed at which we can fix other compiz/GL problems.
The impact is that systems requiring fglrx for 3D (ie, not supported by radeon) won't be able to get the Unity experience.

For historic reasons, if fglrx detects the compiz program, it falls back to "indirect mode" OpenGL.
This fix works in combination with a soon to be released fglrx driver (version latter than 8.84.60).
With this patch, Unity will work on systems with the fglrx driver.

Symptoms:
    With a non-patched version of fglrx the following fails:
        - running "compiz --replace" with the Unity plugin enable will fail at startup.
        - running "unity" also fails at startup.
    Make a copy of the compiz binary (in /usr/bin) and name it "compiz-hack". If you run "compiz-hack --replace" with the Unity plugin enable, then Unity will not fail.

Evidences of fglrx working with this compiz patch:
    - running "compiz --replace" with the Unity plugin enable should not fail at startup.
    - running "unity" should not fail at startup.

    - The following examples in Nux should run:
        gputests/texture_copy_blur
        gputests/texture_blur

    - auto-pilot reported PASS:
        Xlib.protocol.request.QueryExtension
        Showing tool tip...
        Showing quicklist...
        Dragging entire launcher...
        (32, 57)
        pressing
        releasing
        Moving launcher icon along edge...
        Dragging launcher straight out and dropping...
        Dragging a launcher icon out, and moving it...
        PASS

The fix has been merge in lp:~unity-team/compiz/trunk revision 2721
This fix needs a patched driver from AMD.
