[knoppix bootscreen, click to zoom][knoppix booting, click to zoom][knoppix desktop, click to zoom]


  • Version 7.4.2 of KNOPPIX is based on the usual picks from Debian stable (wheezy) and newer Desktop packages from Debian/testing and Debian/unstable (jessie). It uses kernel 3.16.3 and xorg 7.7 (core 1.16.1) for supporting current computer hardware.
  • In addition to the 32bit standard kernel, the 64bit version of the same kernel is installed on the DVD edition, supporting systems with more than 4GB of RAM and chroot to 64-bit installations for system rescue tasks. In the DVD version, the bootloader will start the 64bit kernel automatically if a 64bit-capable CPU is detected (if not manually specified otherwise).
  • Bugfixes:
    • Updated Kernel (3.16.3) und xorg (core 1.16.1),
    • Security: Firefox (iceweasel 32.0.3), Chromium (37.0.2062.120), libnss3 (3.17.1) update,
    • Gnome desktop starts again using boot option knoppix desktop=gnome, if supported by graphics card,
    • Patch for the bash-Shell against the "ShellShock" bug in the environment variable parser,
    • Updated: udev -> systemd-udev (215) + dbus (1.8.8) for automatic hardware management and autostart of systemdcomponents,
    • Updated: LibreOffice (4.3.2), Gimp (2.8.14), KDE libraries (4.8.4), Network Manager (, isc-dhcp Client+Server (4.3.1-2),
    • Security updates from Debian testing/updates and stable/updates.
  • New: Directly start a program as process 1 instead of init via boot option knoppix init=program_name (for example, knoppix init=/bin/bash or knoppix init=vim).
  • Bugfixes 7.4.1 vs. 7.4.0:
    • transparency problem (invisible mouse pointer) when using the "write on screen" or "fullscreen zoom" plugin fixed in compiz behoben,
    • stabilized speech-dispatcher 0.8 for ADRIANE,
    • added boot option "knoppix mkimage" for auto-creating writable overlay on flash-knoppix-installed USB flash disk, should behave as expected in "read only like DVD" install option,
    • dia and wxmaxima startable again,
    • network-manager+modem-manager update.
  • New in 7.4.0:
    • New, experimental version of 3D window manager compiz,
    • Partly integration of system start and service manager systemd, which is apparently going to be standard in the next version of Debian, with a workaoround in order to keep the quicker, script-based KNOPPIX system start with sysvinit,
    • LXDE (Default) with filemanager PCMANFM 1.2.1, KDE 4.8.4 (boot option knoppix desktop=kde, DVD version only), GNOME 3.8.4 (boot option knoppix desktop=gnome, DVD version only),
    • Wine version 1.7 (git) for integration of Windows (TM) based programs,
    • Virtualbox version 4.3.14 (DVD version only) and qemu-kvm 2.0.0 for (para-)virtualization.
    • Optional integration of the Tor network for anonymously surfing the web (DVD version only).
    • Easy Desktop-Export via VNC and RDP for Remote Desktop Viewing under Linux und Windows (especially interesting for teachers),
    • SAMBA network volume search & mount utility smbmount-knoppix,
    • Possibility to update an existing flashdisk installation of KNOPPIX via flash-knoppix,
    • New version of the elinks text web browser, Templates for mail configuration with mutt, automatic page orientation detection in scanning/ocr utility adriane-ocr and keyboard mailing program KARL in ADRIANE Audio-Desktop,
    • bitcoin core for managing Bitcoin wallets (makes only sense on USB flash drives >= 32GB because of the current blockchain size),
    • added a tiny "boot only" CD image inside the "KNOPPIX" directory for computers that can only boot from CD, but not from DVD or USB flash drive (please use boot option "knoppix lang=en" if it's booting in german instead of english language by default),
    • Experimental support for UEFI-Boot after installation on USB flash disk.

Complete software list: -> DVD (~3500 software packages, over 10GB uncompressed, cloop-compressed to 4GB).

A.D.R.I.A.N.E. (Audio Desktop Reference Implementation And Networking Environment) is a talking menu system, which is supposed to make work and internet access easier for computer beginners, even if they have no sight contact to the computers monitor. A graphical environment with also talking programs and arbitrary magnification using compiz-fusion, is another option.

CD / DVD / USB Versions - which files do I need?

The current public beta release of KNOPPIX 7.4.2 DVD is available in different variants for download at the KNOPPIX-Mirrors.

file namecontent
KNOPPIX_versionDVD-date-DE.isoKNOPPIX, DVD-Version, default language german, ISOfile format
KNOPPIX_versionDVD-date-EN.isoKNOPPIX, DVD-Version, default language english, ISOfile format
*.iso.md5checksum file (MD5) for md5sum for checking CD-image after download
*.iso.sha1checksum file (SHA1) for sha1sum for checking CD-image after download
*.iso.*.ascDigital signature for verifying authenticity of checksum files and images after download

For burning a CD or DVD, only one single .iso file matching your language and version choice, is sufficient.

Additionally, several independent vendors offer readily burned and verified CDs, DVDs and USB-memorysticks saent out via postal service.

Since there are so many different media capacities, there is no readymade image for booting off memorystick available for download. But it is easy to create a bootable USB-stick or flashcard from a running KNOPPIX system, as described in the next section.

Booting from Flash

[Picture of a SD-flashdisk]

In order to create a bootable USB-medium (memory flashdisk, SD-card, digital camera with USB connector, cellphone with microSD, ...), the program flash-knoppix can be started from a running KNOPPIX system. This program installs all needed KNOPPIX files onto the FAT-formatted flashdisk, and creates a boot record for it. If desired, the target medium can be partitioned and fornatted, or left in its inistal state, so that existing files stay intact. The KNOPPIX Live System starts and runs about factor 5 faster from USB flash disk than from CD or DVD!

After having copied the system to flash, using the persistent KNOPPIX image (overlay feature) or an additional Linux partition, it is possible to also store files permanently in live mode. That way, personal settings and additionally installed programs survive a reboot.

Update: Computers without DVD drive

The flash-knoppix script since Knoppix 7.4.0 supports on-the-fly conversion of a DVD ISO image for direct flashing of a USB pendrive or disk. By using this, the intermediate step of burning a DVD and booting from it, can be skipped. For burning a CD or DVD, only one single .iso file matching your language and version choice, is sufficient. For using this feature, just add the name of the .iso file as commandline parameter to flash-knoppix like this: flash-knoppix KNOPPIX_V7.4.1DVD-2014-09-28-EN.iso
