[Bug 250792] [NEW] Adobe Flash hardware acceleration support (GPU)

[Launchpad Bug Tracker]

Hello,

I'm trying to benefit from Adobe Flash Player 9.0.115.0 (and above)
capabilities for fullscreen hardware rendering. Adobe's blog[1] explains
that the graphic card must support the following Open GL features:

    * GL_ARB_multitexture
    * GL_EXT_framebuffer_object
    * GL_ARB_shader_objects
    * GL_ARB_shading_language_100
    * GL_ARB_fragment_shader

So I installed the restricted drivers provided by ubuntu to enable all
those features hoping my card have all of these. Great, I now have
"direct rendering: yes" and greping those listed GL_* from the glxinfo
command shows that my ATI X1250 card (integrated in motherboard) is
capable.

But Adobe also states the following:

"""
Also, for fullscreen OpenGL acceleration, the Flash Player requires that the client glx vendor string be something besides "SGI". Official drivers from, e.g., ATI and Nvidia hopefully do not have "SGI" in this field (check the 'glxinfo' command, for this string and for the extensions listed above).
"""

glxinfo | grep "client glx vendor" outputs:
client glx vendor string: SGI

So I made a fresh new install on my test PC, and decided to install
ATI's driver directly from their web site (rather than ubuntu's
restricted modules version), hoping that "glxinfo" would output
something else than SGI. But I get the exact same data from "glxinfo".

Would it be possible to change the string as a work around? This pretty
much means that *all* users don't have fullscreen hardware acceleration.
