Other 'X' applications appear to be ok, like running adept, the ubuntu package 
manager from here.  However it doesn't use relatively large initial splash 
images either.

FWIW, I've now installed the nvidia driver on both ends of this 100 foot 
length of cat 5, previously it was just on this box, but I haven't repeated 
the experiment since its such a pita to go reboot both machines.  But, since 
kmail keeps a scratch copy of this message, I will go and attempt that now. 
We might be chasing a will-of-the-wisp too since emc itself has been updated 
from 2.2.2 to 2.2.3 since the last such occurrence.

Mmm, fails, with this on the konsole as it exits, starting with the login:

The splash image did display, and cleared just fine, no crash.

Now, is that a font problem because my fonts don't match those available on 
the kubuntu box, or ??? Neither of the quoted trace files above contain 
anything related to a font problem so I won't paste them here.

dmesg however, points to another problem:

I'm running out of hair here.  How are these related?

Mmm, FWIW, I don't even build parport here, nothing uses it on this machine, 
but then that has been the case for several years and it has not been a 
problem previously so I have good reason to think its a mochs nichs.  And an 
lsof|grep '/dev/' contains no references indicating the parport was 
previously spoken for.

I sure could use some help here folks.  Thanks.
