Are you tired of seeing this result:

rabbit at rabbithole:~/warren/cogvm/image$ cogvm Mushroom.4.image
squeak: could not find any display driver
Aborted (core dumped)

I am! Thank you for the help today. Unfortunately this is still an issue 
for me on both laptops: 32-bit and 64-bit OS.  Both were working as 
well. I reinstalled the 64-bit and it failed right off the start. The 
commonality to all three failures was the fact that I did these below 
commands prior to it failing this way, everytime. I think it is the 
upgrade that does it in. I'll reinstall 32-bit and try without these 
commands; let you know.

Robert

sudo apt-get update
sudo apt-get upgrade

and I ran this script for system libraries for 32-bit squeak.

    #!/bin/bash

    # ARGUMENT HANDLING
    =============================================================
    if { [ "$1" = "-h" ] || [ "$1" = "--help" ]; }; then
         echo "Install libraries required to build the pharo VM under
    ubuntu.
    "
         exit 0;
    elif [ $# -gt 0 ]; then
         echo "--help/-h is the only argument allowed"
         exit 1;
    fi
