KNOPPIX 7.7.1 Public Release

Contents

• Version 7.7.1 of KNOPPIX is based on the usual picks from Debian stable (jessie), testing (stretch) and unstable (sid) for newer graphics drivers or desktop software packages. It uses Linux kernel 4.7.9 (not affected by the "Dirty Cow Bug") and xorg 7.7 (core 1.18.1) for supporting current computer hardware.
  
• Kernel Patches: cloop, aufs, BFQ, TCP Stealth.
• 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).
• New in 7.7.1:
  • Kernel and system software (Debian Jessie+Stretch) updated,
  • New, experimental version of 3D window manager compiz 0.9.12.2,
  • LXDE (Default) with filemanager PCMANFM 1.2.4, KDE 5.7.4 (boot option knoppix desktop=kde, DVD version only), GNOME 3.22 (boot option knoppix desktop=gnome, DVD version only),
  • Wine version 1.9.20 (git) for integration of Windows (TM) based programs,
  • qemu-kvm 2.6 for (para-)virtualization.
  • ADRIANE Audio-Desktop: mpsyt Youtube (TM)-Client for console, Orca 3.20.2 for compiz,
  • electrum 2.6.4 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,
  • Experimental support for UEFI-Boot and Secure Boot after installation on USB flash disk.
  • Versioning: If many Knoppix-installed USB flash disks or harddisks are present, the boot system now finds the kernel-matching KNOPPIX overlay automatically -> avoids errors caused by mismatching Kernel/System/Overlay versions.
  • The live installer flash-knoppix now shows a "honest" progress bar by measuring the real space allocation during copy. Also, the syslinux-supplied master boot record is used instead of ms-sys.

Complete software list: -> DVD (~4000 software packages, over 11GB uncompressed, cloop-compressed to 4.3GB).

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 7.7 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

ADRIANE

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.

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

The current public beta release of KNOPPIX 7.7.1 DVD is available in different variants for download at the KNOPPIX-Mirrors.

Caution: Because the DVD image is larger than 4GB, it cannot be stored on a FAT32 partition! -> Use NTFS or a linux file system.

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

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_V7.7.1DVD-2016-10-22-EN.iso

Micro-Remastering

Boot options like "adriane" can easily be preset by changing syslinux.cfg after having copied the CD to a bootable memorystick using "flash-knoppix":

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