I'll google some more, that thread never did show the section of the
xorg.conf that needs this, and it doesn't even exist as a commented option
in mine.
One of the other threads said to add export LIBGL_ALWAYS_INDIRECT=1 to the
~/.bashrc, so I did that and opened a new terminal session. There was no
significant diff in glxgears on this machine, well above 4000 fps.
So I added that line to shops ~/.bashrc, logged out and back in.
gene@shop:~/emc2/configs/genes-mill$ glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
32511 frames in 6.9 seconds
32512 frames in 6.8 seconds
32511 frames in 6.8 seconds
32512 frames in 6.8 seconds
obviously as bogus as a $3 bill, refresh rate visually was 1 or 2 a second.
Then I changed the .ini file back to axis, and it actually opened & drew
the axis screen, for maybe 300 milliseconds, then went away again leaving
this behind on the terminal screen:
.gene@shop:~/emc2/configs/genes-mill$ emc -l
EMC2 - 2.4.6
Machine configuration directory is '/home/gene/emc2/configs/genes-mill'
Machine configuration file is 'genes-mill.ini'
Starting EMC2...

Xlib length error)

Shutting down and cleaning up EMC2...
Cleanup done
EMC terminated with an error. You can find more information in the log:
/home/gene/emc_debug.txt
and
/home/gene/emc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal
The quoted files contained no new info.
So, a little closer, but still no bananna.
But I just found this in the glxinfo output, looks like forcing the vesa
driver is not complete:
name of display: localhost:10.0
display: localhost:10 screen: 0
direct rendering: No (LIBGL_ALWAYS_INDIRECT set)

the above is this machine obviously, next is from shop I believe
=========================

===================
and this next is this machine again.
===================
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 9400 GT/PCI/SSE2/3DNOW!
OpenGL version string: 1.4 (2.1.2 NVIDIA 260.19.29)
The glx extensions do not match up, but no clue how to fix & I'm going back
to bed, it wasn't really my time to get up yet.
Thanks Kirk.
