Knoppix
From LXDE.org
Knoppix, or KNOPPIX (pronounced /k'nop.ɪks/), is an operating system based on Debian designed to be run directly from a CD / DVD. Knoppix was developed by Linux consultant Klaus Knopper. When starting a program it is loaded from the optical disc and decompressed into a RAM drive. The decompression is transparent and on-the-fly.
Knoppix 6.0 in its first release on Live CD, so called Microknoppix, is supplied with LXDE as main windows manager.
[edit] Installation
(The following has been tried and tested on Knoppix 6.2 on a system with Intel(R) 945 Express chip-set graphics and a ViewSonic VA1616w wide-screen LCD running at 1366x768)
If you get a black strip/bar on your desktop after LXDE has finished loading,you most probably need to alter Compiz settings.
To do so,first go to Preferences>CompizConfig Settings Manager in the LXDE menu
In the new window that opens,click on `General options`.
Next,go to the `Display Settings` tab.
Now enable the checkbox for `Detect Outputs`.You should notice the change immediately and now no usable portion of the screen will be masked by any black area.
Click `Back` and then `Close`.
