I installed gdm and it works fine.  I'm happy to help you debug this, but if
you have more urgent requests, please feel free to ignore this.  Thank you for
helping me pin this down.

Progress!!

Starting from the login screen, I press control-alt F2 to bring up a command
line.  Then I run startx.  I don't get a window manager, but I can find my way
to xterm and then work from the command line after X starts.  glxgears looks
normal - smooth and as quickly as I believe the 9550 can go. :)  Opening
firefox, CNN and youtube videos play smoothly.

>From your comments, I believe I have sidestepped lightdm. I opened synaptic and
reinstalled lightdm and associated programs.  I then minimized synaptic and now
I know what the display manager does.  That's OK, I'll be rebooting anyway.

Next steps?  I believe there is /usr/lib and an /etc folders.  Can I clean them
out and do another re-install?  Will the config files get regenerated?

Thanks

I uploaded the lightdm log from an attempted login when I had stopped the
ALWAYS_SOFTWARE flag from getting set.

Thanks for staying with this one.

unset LIBGL_ALWAYS_SOFTWARE; /usr/lib/nux/unity_support_test -p

yields:

***

I assume (don't know how to test and gdm is not installed) lightdm is my
display manager, I reinstalled lightdm but no change. Logs look ok, I am going
to restart without software rendering (so X fails and I get kicked back to
login screen) and check those logs.

That doesn't show any problem. Maybe check the display manager (lightdm?) log
files to see if the X server stderr contains more information.

Meanwhile, you could let it set LIBGL_ALWAYS_SOFTWARE to get into X, then run
unity_support_test something like this:

( unset LIBGL_ALWAYS_SOFTWARE; /usr/lib/nux/unity_support_test -p )


> Radeon 9600 vs. 9550?

Just two different marketing names for the same hardware.


> Not sure anybody needs to run Xorg -configure anymore, [...]

Nobody does. It's been deprecated and barely working for a long time.

X won't start without LIBGL_ALWAYS_SOFTWARE set.  Log file is Xort.0.log.sav
above.

I notice that Xorg.0.log and lspci identify my card in different ways?  Radeon
9600 vs. 9550?

>From Xorg.0.log
(--) RADEON(0): Chipset: "ATI Radeon 9600 AS (AGP)" (ChipID = 0x4153)

***

Another thought... 

Not sure anybody needs to run Xorg -configure anymore, but I tried it to see if
I could learn anything and got the message "Number of created screens does not
match number of detected devices".  The configure process noted three screens
and three monitors, I believe my card supports my monitor and an external TV.

Thanks, but LIBGL_ALWAYS_SOFTWARE only affects libGL, not the X server. We need
to see the output of unity_support_test without it set.

Does Unity work if you hack the script not to set LIBGL_ALWAYS_SOFTWARE?

LIBGL_ALWAYS_SOFTWARE forces software rendering regardless of its value. You
need

 unset LIBGL_ALWAYS_SOFTWARE

instead, or just don't set it in the first place.

So, why does unity_support_test fail without LIBGL_ALWAYS_SOFTWARE set?

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... 

/usr/lib/nux/unity_support_test -p
OpenGL vendor string:   VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits)

Not blacklisted:  yes
GLX fbconfig: yes
GLX texture from pixmap:  yes
GL npot or rect textures: yes
GL vertex program:yes
GL fragment program:  yes

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

[54.123] (EE) Failed to load module "r300" (module does not exist, 0)

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

libGL is directly loading swrast instead of r300 for some reason. Make sure the
environment variable LIBGL_ALWAYS_SOFTWARE is not set.

Added dri configuration file, but realized that still left me with software
acceleration.  Still puzzled.

I posted the output, it looks like some things are missing. Tonight I'll try to
get them installed. Thanks.
