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:
[root at coyote ~]# ssh -Y -l gene shop

EMC terminated with an error. You can find more information in the log files

as well as in the output of the shell command 'dmesg' and in the terminal

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.
