I am getting a completely unmodified atlantis window.  The window size
is unchanged (as would not be the case for crdemo.conf) and the blank
window which is supposed to be there according to
[http://chromium.sourceforge.net/doc/chromium2.html#CompilingCr] does
not appear.  Moreover, as I've been testing more this morning, none of
the client spus are taking effect.  For example, the following would
render something very different from the original atlantis:

$python ~/cr-1.9/mothership/configs/crdemo.conf 'atlantis -s 100' hiddenline
$python ~/cr-1.9/mothership/configs/crdemo.conf 'atlantis -s 100' print

Nevertheless, I am still getting the same old atlantis window.

I've been leaving the mothership variable out as localhost is correct.
 I'll try it just to remove the errors.  I'll report a change if there
is one.  Right now, my PC has capacity for 6 monitors over three
nvidia graphics cards.  I have no need to add extra network nodes at
this time.  Would my hardware configuration influence the results?

Messages from the apps are as follows:

Thank you for using Chromium!

Would you like me to post screenshots somewhere?

I'm going to add my user to the video group (get permissions to the
nvidia device) and I'll try it again.

[Time passes.]

I also added the '-mothership localhost' arguments to the crserver,
which removed all of the relevant errors.

Aside from removing the permissions errors and the framerate tripling,
there was no effect on the test with regards to the nvidia
persmissions.

317.4 fps

Still, the lack of spu handling and the lack of an extra window persist.
