This is an old Packard Bell Computer as well. Most of the 
time it freezes just trying to open Firefox with the GLIB 
CRITICAL error. I'll see if it is possible to increase its 
RAM as Daniel suggests?
Does anyone have a suggestion for a Linux version that needs 
low RAM.  This computer is used for pretty minimal stuff. It 
is used with Putty as a dumb terminal, is used to open 
spreadsheets and create spreadsheets on a NFS with 
LibreOffice and occasionally to look up something quickly on 
the web. Occasionally it will open a simple drawing in 
inkscape. I'm surprised that inkscape doesn't crash it if it 
if it is a memory issue.
