KNOPPIX 8.2.0 Public Release

[knoppix booting animation][knoppix desktop animation]


  • Version 8.1 of KNOPPIX is based on the usual picks from Debian stable (stretch), testing (buster) and unstable (sid) for newer graphics drivers or desktop software packages. It uses Linux kernel 4.12.7 and Xorg 7.7 (core 1.19.3) for supporting current computer hardware.
  • Kernel Patches: cloop, aufs, TCP Stealth.
  • Both 32bit and 64bit kernel supporting both old and new computers, the 64bit version also supporting systems with more than 4GB of RAM and chroot to 64-bit installations for system rescue tasks. The bootloader will start the 64bit kernel automatically if a 64bit-capable CPU is detected (if not manually specified otherwise).
  • For Computers that can only start from CD, not from DVD or USB flash pen, a tiny bootable CD image has been placed in the "KNOPPIX" folder, which can be burned and used together with the full USB or DVD version in order to start on old computers.
  • New in 8.1:
    • BFQ (Budget Fair Queue Scheduler), now included in the standard kernel within the multipath scheduler, austomatically activated for slow disks,
    • Kernel and system software (Debian stretch+buster) updated,
    • LibreOffice 5.4.1, Gimp 2.8.20
    • Chromium 60.0.3112.78 and Firefox (ex Iceweasel) 55 Web Browser with ublock Origin and NoScript Security-Plugin (--> Firefox no longer supports sound, check "bugs" section)
    • Automatic expansion of overlay partition on USB flash pen without reboot (!) after 1:1 copy of ISO hybrid image on USB flash pen (see New hybrid layout),
    • Personal remastering option when copying to USB flash pen using flash-knoppix
    • New programs: etherape (graphical network monitor), archivemount, terminator (terminal emulator with many features),
    • Mathematical software maxima 5.40, also integrated as live session in Texmacs,
    • New version of 3D window manager compiz,
    • LXDE (Default) with filemanager PCMANFM 1.2.5, KDE 5.8 (boot option knoppix desktop=kde), GNOME 3.24 (boot option knoppix desktop=gnome, DVD version only),
    • Wine version 2.0.0 (git) for integration of Windows (TM) based programs,
    • qemu-kvm 2.8 for (para-)virtualization.
    • electrum 2.7.9 for managing Bitcoin Wallets,
    • 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,
    • UEFI secure boot support

New partition layout

Hybrid DVD or USB Flash disk (Original.iso)
PartitionSizeFile systemContent
14GBiso9660 (ro)Compressed Knoppix-filesystem (KNOPPIX/KNOPPIX*), Bootfiles, Info
220MBFAT32EFI-Bootloader and boot files (copy). Invisible on DVD
34MBReiserfsEmpty Linux file system which, in case of a writable medium, will automatically get expanded to maximal available size and is used as writable overlay. Invisible on DVD.

With the new Hybrid layout of the ISO file, the file can be copied directly to USB flash disk, either using standard Linux tools like dd or cp, or programs like Win32 DIsk Imager. In this case, the first partition is read-only because of the iso9660 file system. Because od that, boot options cannot be changed permanently.

dd if=KNOPPIX_V8.1-2017-09-05-EN.iso of=/dev/sdb bs=1M

A better way of installing, is using --> flash-knoppix, which will create the simpler and writable layout with one FAT32 and one Linux partition on USB flash pen. Optionally, a personal remastering can be chosen in version 8.1.

UEFI Secure Boot

KNOPPIX 8.1 generally supports booting in UEFI and Secure Boot after installation on USB flash disk. But in order to use this feature, an entry in the UEFI firmware is necessary at first boot attempt. --> Find quick instructions here.

Special Feature "Everything 3D"

"3D Design and 3D printing" is a great field of play for creative persons and makers. Also, many lectures and talks held be Klaus Knopper have touched the topic this year. Because of that, the KNOPPIX DVD version 8.1 features the following popular 3D programs:
  • OpenScad - 3D construction without drawing skills
  • Slic3r - G-Code printing preparation for 3D models
  • Blender*) - extensive 3D modelling and animation program
  • Freecad*) - Draw 3D models
*) Because of space considerations, included inside the second overlay image KNOPPIX/KNOPPIX1

Known bugs in version 8.1

  • Because of a controversal design decision of its developers, the popular Firefox web browser ceased to support direct audio playing under Linux starting from version 52. An error message displaying on pages like youtube, suggesting to install "pulseaudio" (which is already installed), is misleading and provides no solution. More about this at the Mozilla bugtracking pages at:
    Workaround: The Chromium web browser, like all other programs using sound in Knoppix excepting Firefox now, does not have this problem and is therefore now set as default browser in the LXDE desktop menu starting from Knoppix version 8.1.


[Penguin with sunglasses]

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, is another option.

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 formatted, 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_V8.1DVD-2017-09-05-EN.iso

Change the upper line



DEFAULT adriane

for automatically starting ADRIANE on boot. This is already default in all ADRIANE iso files.
