In case anyone is watching this thread I finally solved the problem by reinstalling Linpus and then installing desktop-switch-0.3-1.i386.rpm.gz, which I found at a German Blog http://www.iphpbb3.com/forum/39151476nx ... -t218.html
. The defualt archive GUI in Linpus wouldn't work for me so I had to use the terminal. I think it was gzip -d desktop-switch-0.3-1.i386.rpm.gz . Then I installed it with sudo rpm -i desktop-switch-0.3-1.i386.rpm .
It adds the icon to the panel at the bottom allowing you to switch between screens.
Hope this helps someone else,
