About

For questions about Knoppix, a Linux distribution designed to be run directly from a live CD, DVD or USB flash drive.

Knoppix is a Debian-based Linux distribution designed to be run directly from a Live CD, DVD or USB flash drive. It was one of the first Live CDs available, and is known as the "original" Debian-based Live CD.

It is a RAM-resident distro, meaning it is designed to load everything into RAM at start-up, run its full functionality in the Live session, and have the capability for changes to persist beyond the session. Text mode requires only 32 MB of RAM. At least 128 MB is needed for graphics mode with LXDE (at least 512 MB of RAM is recommended to use the various office products).

The Knoppix Live System starts and runs about 5 times faster from a USB flash drive than from a CD or DVD. It can also be installed on a hard drive (although it will still run from RAM, the hard drive speeds startup and provides more storage capacity).

Although it is "lightweight" to operate from RAM, the KDE desktop is available as an option, as well as the typical "full sized" applications (although these may be optimized to reduce RAM requirements).

There are over three dozen distros descended from Knoppix, including:

  • Damn Small Linux (based on Knoppix)
  • Kali Linux (originally based on an offshoot of Knoppix, but now based directly on Debian Testing)
  • Deepin (originally based on an offshoot of Knoppix, but now based directly on Debian Unstable)
