Unlike Windows or Mac OSX, Linux has many different graphical interfaces available.
Gnome and KDE are the two most common Desktop Environments. However, for performance reasons, CASLab makes use of a customized version of the LXDE desktop environment.
Documentation, including screenshots, should be available soon. In the meantime, please see the documentation on using the CASLab Linux Live DVD. It is almost identical.
As always, we are interested in your feedback. Please send any questions or comments about this document or the Linux image to: firstname.lastname@example.org
