As I suspected.  Now we just need to find out which piece of hardware, 
which driver, or which piece of software is to blame.  Only you can do 
that for us.

The ssh-agent processes are a side-effect of the fact that you are using 
startxwin.sh to startup (as opposed to startxwin.bat).  I inherited 
those scripts from the original author and have taken a policy of not 
changing things that I don't understand.  I have no clue what ssh-agent 
does, I don't pretend to have a clue, and I don't care to ever have a 
clue.  I will follow advice if someone is willing to explore what the 
heck ssh-agent does and tell me either to keep or remove that line near 
the top of startxwin.sh that runs it.  I think we had discussed this 
before a long time ago, but either the discussion was not decisive, or I 
forgot to remove that line.

Either way, someone else is going to have to help with this one.
