--- Comment #7 from Elven Decker <sailing at together.net> ---
Good news and bad news, and light at the end of the tunnel

LIBGL_ALWAYS_SOFTWARE was getting set to one in
/etc/X11/Xsession.d/50_check_unity_support. So I overrode the value as below:

cat 50_check_unity_support
# This file is sourced by Xsession(5), not executed.
# If the hardware does not pass unity_support_test, fall back to LLVMpipe
# which does.

if [ "x$DESKTOP_SESSION" = "xubuntu" ]; then
    /usr/lib/nux/unity_support_test || export LIBGL_ALWAYS_SOFTWARE=1
fi
export LIBGL_ALWAYS_SOFTWARE=0

which set LIBGL_ALWAYS_SOFTWARE to zero:

printenv | grep ALWAYS
LIBGL_ALWAYS_SOFTWARE=0

Unfortunately there was no change in the behavior of the system and we still
see unity not supported...

based on your comment about the r300 driver, I tried a forced loading of R300
by putting it into an xorg.conf... in Xorg.0.log we see
[    54.122] (II) LoadModule: "r300"
[    54.122] (WW) Warning, couldn't open module r300
[    54.122] (II) UnloadModule: "r300"
[    54.123] (II) Unloading r300
[    54.123] (EE) Failed to load module "r300" (module does not exist, 0)

I'm clearly missing a package... which one??  Thanks
