If you're using an installed LinX program on a PC in a public computing lab, you should be able to start it by double-clicking on the linx booter and then OK'ing the shutdown. You'll see a lot of text scroll by, and then you chould get a login screen.
To quit LinX, first log out from your remote session (this should give
you a new login prompt), and then use ctrl-alt F1 to get a text
screen, followed by ctrl-alt-delete to reboot (into windows).
If you want to try installing LinX on your own PC,
you can get a Zip file here that includes setup
instructions.
If you have questions about LinX, send us
email.
