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 on Knoppix 6.2 on a system with Intel 945 Express chipset graphics and a ViewSonic VA1616w widescreen LCD running at 1366x768)
If you get a black strip/bar on your desktop after LXDE has finished loading,you most probably need to disable Compiz as your default window manager and use OpenBox instead.
To do so,first become root in Knoppix and then open the file /etc/xdg/lxsession/LXDE/config
Change the value of the window_manager variable to `openbox-lxde`(without the quotes) so that the line reads
window_manager=openbox-lxde
Next,save the change and close the file.
Now permanently delete the file /home/knoppix/.config/lxsession/LXDE/config
Logout from the root login and logout from LXDE as well.The black bar/strip should have disappeared when you login the next time(which happens automatically in an out-of-the-box Knoppix installation).
