DebEX Barebone Build 170822 with LXDE: Create you own Debian 9 “Stretch” system in the easiest possible way!

Aug

2017

About DebEX Barebone, DebEX Gnome and DebEX KDE Linux 64 bit
All three systems/distributions are a based on Debian. DebEX KDE is based on Debian Jessie (Debian 8). DebEX Barebone and DebEX Gnome are based on Debian 9 (Stretch) and Debian unstable (Sid). LXDE is used as Desktop environment in DebEX Barebone. Gnome 3.22 and Mate 1.16 are used in DebEX Gnome. KDE 4.14.2 and KDE Plasma Desktop 5:84 are used in DebEX KDE. DebEX Barebone LXDE uses my special kernel 4.12.0-12-exton. (Kernel 4.12.8 – latest stable kernel). DebEX Gnome uses my special kernel 4.8.0-21-exton. (Kernel 4.8). DebEX KDE uses my special kernel 4.8.0-18-exton. (Kernel 4.8-rc8). The system language is English (in all three versions of DebEX).

NEWS 170822 about DebEX LXDE – a Refracta Build
A new version of DebEX Barebone with LXDE and kernel 4.12.0-12-exton (equivalent to Kernel.org’s latest stable kernel 4.12.8) is ready. All packages have been updated to the latest version as of August 22, 2017. DebEX Barebone is now based on Debian 9 Stretch and Debian unstable – Sid. I have replaced Google Chrome with Firefox 55.0.2 (for Netflix).

What’s new in kernel 4.12?

Important about Refracta
You can use the Refracta tools (pre-installed in DebEX LXDE) to create your own installable Debian Stretch Live DVD once you have installed DebEX LXDE to hard drive. I mean change everything and then create a whole new Debian Stretch live system. When you start Refracta it will look like this. You don’t even have to install DebEX to hard drive before you can use the Refracta tools. If you have plenty of RAM you can create a new (your own!) Debian 9 system while running DebEX from DVD or a USB stick. Please note that the whole Refracta process (creating your new ISO) will only take 5 – 10 min! You’ll find the ISO in /home/snapshots.

SCREENSHOTS

RaspEX for Raspberry Pi 3/2 – Build 170810 – based on Ubuntu 17.04 with LXDE and kernel 4.9.41-exton-v7+

Aug

2017

NEWS 170810 about RaspEX for Raspberry Pi 3 and Pi 2
I have upgraded the whole system and replaced the old kernel 4.4.49 with “my own” compiled kernel 4.9.41-exton-v7+. RaspEX Build 170810 is a Linux ARM system for Raspberry Pi 3 and Pi 2. It is based on Debian 9, Ubuntu 17.04 and Linaro (Open Source software for ARM SoCs). In this new version (170810) I’ve installed Wicd Network Manager and replaced Chromium with Firefox with better support for YouTube. I have also installed Samba and VNC4Server so you can connect to your Windows computers in your Home Network and/or control RaspEX on your Raspberry Pi 3 or Pi 2 from your Windows computers with VNC Viewer and/or PuTTY (Telnet and SSH client). Furthermore some extra Network Tools, Midori Private Browser, SMTube (YouTube browser which allows to browse, search and play YouTube videos) and PulseAudio for better sound in YouTube. Study all installed packages in RaspEX Build 170810.

Compatibility :: August 2017
Unfortunately not all systems made for Raspberry Pi 2 will run on the new Pi 3. They need to be upgraded with a new kernel. I therefore have to upgrade the systems I distribute. I.e. RaspEX, RaspEX with OpenCPN, RaspAnd Lollipop, RaspAnd Marshmallow, RaspAnd Nougat 7.1.1, RaspAnd 7.1.2 and RaspArch. I have now (170810) upgraded all systems. Read about the new Raspberry Pi 3…

Kernel
Kernel 4.9.41-exton-v7 is used.

How do I install RaspEX in Windows?
Just like any other Raspberry Pi system. I.e.: Unpack the downloaded ZIP file (raspex-ubuntu-17.04-lxde-1190mb-170810.zip) and transfer the IMAGE file (raspex-ubuntu-17.04-lxde-3050mb-170810.img) to your Micro SD card of at least 8GB. For that you shall use Win32DiskImager in Windows.

ExTiX 17.4 – “The Ultimate Linux System” – with LXQt 0.11.1, Nvidia 381.09 and kernel 4.10.0-19-exton – Build 170418

Apr

2017

I have made a new version of ExTiX – The Ultimate Linux System. I call it ExTiX 17.4 LXQt Live DVD. (The previous version was 17.2 from 170320).

ABOUT
ExTiX 17.4 LXQt DVD 64 bit is based on Debian 8.7 Jessie/Debian 9 Stretch and Ubuntu 17.04 Zesty Zapus, released 170412. The original system includes the Desktop Environment Unity (Ubuntu). After removing Unity I have installed LXQt 0.11.1. LXQt is the Qt port and the upcoming version of LXDE, the Lightweight Desktop Environment. It is the product of the merge between the LXDE-Qt and the Razor-qt projects: A lightweight, modular, blazing-fast and user-friendly desktop environment.

NEWS ABOUT ExTiX 17.4 build 170418 with LXQt Desktop environment
1. ExTiX LXQt is based on Ubuntu 17.04 Zesty Zapus. LXQt 0.11.1 is used as Desktop environment. All packages have been updated to the latest version by 170418. Kernel 4.10.0-19-exton is used. (Kernel.org‘s kernel 4.10.8).
2. Google Chrome is used as Web Browser, which makes it possible to watch Netflix movies. It is normally not possible in Firefox (in Linux).
3. I have also installed BlueGriffon 2.3.1 Web Editor. BlueGriffon is a new WYSIWYG content editor for the World Wide Web. Powered by Gecko, the rendering engine of Firefox, it’s a modern and robust solution to edit Web pages in conformance to the latest Web Standards. Only to be compared with Dreamweaver. (In my opinion).
4. Other included important/useful packages are: LibreOffice, Thunderbird, GParted, Brasero, SMPlayer, GCC and other compilation tools so that you can install packages from source. Furthermore “all” multimedia codecs. Everything the average Linux user could wish for I would say.
5. I have also installed Nvidia’s proprietary graphics driver 381.09 in this new version ExTiX LXQt. It has support for the following GPUs: Vulkan, GeForce GTX 1080 Ti,TITAN Xp, Quadro GP100, Quadro P4000, Quadro P2000, Quadro K1200, Quadro M6000, GeForce 920M, GeForce 930A, GeForce 930M, GeForce 940M, GeForce GTX 950M, GeForce GTX 960M and GeForce GTX TITAN X. This driver will be used automatically if your card is supported (if you start up ExTiX in compatibility mode).

WHAT’S SO SPECIAL about ExTiX and especially the new version from 170418?
1. The ExTiX ISO’s are ISO-hybrids, which means that they can very easily be transferred (copied) to a USB pen drive. You can even run ExTiX from the USB stick and save all your system changes on the stick. I.e. you will enjoy persistence!
2. Another big improvement is that both ExTiX versions can run from RAM. Use Boot alternative 3 (Copy to RAM). When the system has booted up you can remove the disc (DVD) or USB stick. You’ll need at least 2 GB RAM to run ExTiX that way. Running from RAM means that the system will run faster than from DVD or USB stick. Everything will be superfast I would say!
3. All packages have been upgraded to the latest version by 170418.
4. I’ve replaced kernel 4.10.0-14-exton with kernel 4.10.0-19-exton (Kernel.org‘s stable kernel 4.10.8).
5. The installation program Ubiquity (live installer) is now working as intended. I.e. a new user (your user) will be created during the installation process.

SlackEX (Slackware 14.2) Live DVD with KDE 4.14.27, Nvidia 375.39 and kernel 4.10.2-x86_64-exton – Build 170314

Mar

2017

SlackEX is based on Slackware Current/14.2. Slackware is the first widely-used Linux system, which is still developing. Slackware has existed since 1993. The older the fiddle the sweeter the tune or as we say in Sweden: “Gammal är äldst”.

New features in version 170314 of SlackEX
I have replaced kernel 4.7.1-x86_64-exton with kernel 4.10.2-x86_64-exton with support for “everything”. Most important is that I have changed repositories from Slackware 14.1 to Current. I.e. Slackware 14.2. KDE is upgraded to version 4.14.27 (latest KDE version). All other component software is also upgraded to the latest Slackware Current version by now. I may also mention in particular GParted 0.27.0 (latest, not in Slackware’s repositories), VirtualBox 5.1.16 (latest, not in Slackware’s repositories), Google Chrome (not in Slackware’s repositories), Nvidia’s proprietary Graphic driver 375.39 (latest driver), Gimp 2.8.10 (installed from source), GSlapt 0.5.4b, Slackpkg 2.82.1, Firefox 52.0, Thunderbird 45.2.8, Samba 4.5.5 and GCC 5.4.0. Furthermore I have installed Grub2, which can be used as boot loader (if you want) after a hard drive install. Study the full package LIST. Note: I have replaced Wicd with NetworkManager. It works better in SlackEX.

Install SlackEX to hard drive
Use this INSTRUCTION. You can (if you want) use Grub2 (new GRUB) as boot loader. (Slackware original still uses LILO). You can (of course) also run and install SlackEX in VirtualBox and VMware.

Install SlackEX to a USB stick
Please read my INSTALL INSTRUCTIONS. NOTE: All system changes are PERSISTENT.

Why Slackware?
Slackware is grossly underestimated (in my opinion). This article give you ten (10) reasons to choose Slackware.

News 170309: Yet another version of exGENT (Gentoo) is out. The best version ever…

Mar

2017

NEWS 20170309 ABOUT exGENT
I’ve made yet a new version (20170309) of exGENT based on Gentoo Linux. It uses Xfce 4.12.1 and kernel 4.9.12. It is for the 64 bit architecture. I call it exGENT 2017 Xfce4 Live DVD. It replaces version 20170303. The ISO file is of 2670 MB due to the fact that this version has a lot of packages pre-installed. Despite this exGENT version 170309 runs surprisingly fast from DVD or USB. Even in VirtualBox and VMware. Faster than most other Linux live systems. All installed packages in exGENT have been updated to the latest available version by 170309.

What’s new in exGENT Build 170309?
The boot loader Grub Legacy has been replaced by Grub2. I started this build in the hope that I should be able to implement a new independent installer program called Calamares. I wasn’t able to do it now though. (Many dependencies to satisfy). My old installer script will have to do until I find a solution. Anyway, I think exGENT Build 170309 can be of interest because of the change to Grub2 and the fact that it has one of the newest kernels installed. MOST IMPORTANT: In versions before this one (170309) the file system wasn’t writable when running exGENT live (from DVD). Now you can emerge (install) new programs/packages even while running the system from a DVD or USB stick. If you do that and later decide to install exGENT to hard drive all your changes will follow! Furthermore you can install/transfer exGENT to a USB stick with the dd command in Linux or use Etcher and Rufus in Windows. Watch a screenshot when Etcher is running. Such installations were impossible before.

Used KERNEL
My special kernel 4.9.12-aufs-gentoo-exton corresponding Kernel.org’s kernel 4.9.12.

Feb

2017

NEWS 20170209 about exGENT
I’ve made yet a new version (20170209) of exGENT based on Gentoo Linux. Now with Xfce 4.12.1 and kernel 4.9.8. It is for the 64 bit architecture. I call it exGENT 2017 Xfce4 Live DVD. It replaces version 20160123. The ISO file is of 2590 MB due to the fact that this version has a lot of packages pre-installed. Despite this exGENT version 170209 runs surprisingly fast from DVD or USB. Even in VirtualBox and VMware. Faster than most other Linux live systems. All installed packages in exGENT have been updated to the latest available version by 170209.

Build 170209 of exGENT replaces Build 170206
Today I discovered some errors in exGENT Build 170206. They were not important, but nevertheless annoying. Build 170209 is totally error-free (as far as I know). While I was at it I installed Google Chrome (for all Netflix addicts) and Spotify (for all music lovers).

Used KERNEL
My special kernel 4.9.8-gentoo-exton corresponding Kernel.org’s kernel 4.9.8. It’s the latest stable kernel as of now. (20170209).

What’s new in kernel 4.9.8?
Programs etc
The best thing with exGENT is the premier auto detection of hardware and the ability to easily install the system to hard drive during a live session. Installed programs: Among many others GParted, GNU Emacs, Firefox, Google Chrome, Spotify, Thunderbird, Samba, AbiWord, Nvidia Graphics driver 375.26 and NetworkManager. Furthermore compilation tools so that you can install programs from source the Gentoo way. (After the installation to hard drive).

Quick install to Hard Drive
exGENT Linux can be installed to hard drive in 3 – 10 min. (Depending on computer type). This means that all of you who might hesitate to perform a normal Gentoo installation – which can take up to a couple of days – now have the chance to get this great Linux system (Gentoo) installed on your computers very easy.

SPOTIFY
You can easy and quick install Spotify in exGENT. Just run the command emerge spotify. The installation takes about 1 min.
NOTE: Spotify is pre-installed in Build 170209.

Google Chrome
To be able to run Netflix in exGENT you’ll need Google Chrome. Just install it with the command emerge –ask www-client/google-chrome

Oct

2016

NEWS 161021 about Exton|OS Light Live DVD – ISO file of 970 MB
I’ve made a new extra version of Exton|OS based on Ubuntu 16.10 (alias Yakkety Yak) 64 bit with only a minimum of packages pre-installed. Among them a terminal emulator (LXTerminal), a Web Browser (Google Chrome – so you can run Netflix), SMPlayer, SMTube (YouTube browser which allows to browse, search and play YouTube videos), PCManFM (file manager), NetworkManager, GParted (Partition Editor), Samba (so you can reach your Windows computers), Audacious (a small and fast audio player which supports lots of formats) and Synaptic (Package Manager). I give you the pleasure of installing all extra packages you need after a hard disk installation of Exton|OS Light. Use Synaptic for that. You can of course also install new packages while running the system live (from DVD/USB stick), but nothing will be saved after a reboot. Unless you have followed my USB Install Instruction (under B) or used UNetbootin) and used Boot alternative 2 – Persistent when you have used UNetbootin. If you have plenty of RAM you can even install big programs (such as LibreOffice) while running the system live even from DVD. Exton|OS Light’s Window manager Openbox guarantees lightness and elegance.

Packages
All installed packages in Exton|OS Light have been updated to the latest available version as at October 21, 2016. Study the full package list.

Used KERNEL
My special kernel 4.8.0-25-exton, equivalent to Kernel.org’s kernel 4.8.1. You can download “my” kernel if you want to use it in another Ubuntu/Debian system.

RaspEX for Raspberry Pi 3/2 – Build 161019 – based on Ubuntu 16.10 with LXDE and kernel 4.4.21

Oct

2016

NEWS 161019 about RaspEX LXDE for Raspberry Pi 3 and Pi 2
I have upgraded the whole system and replaced the old kernel 4.1.20 with kernel 4.4.21. RaspEX Build 161019 is a Linux ARM system for Raspberry Pi 3 and Pi 2. It is based on Debian Jessie (Debian 8.6), Ubuntu Yakkety Yak (Ubuntu 16.10, released 161013) and Linaro (Open Source software for ARM SoCs). In this new version (161019) I’ve installed Wicd Network Manager and replaced Chromium with Firefox with better support for YouTube. I have also installed Samba and VNC4Server so you can connect to your Windows computers in your Home Network and/or control RaspEX on your Raspberry Pi 3 or Pi 2 from your Windows computers with VNC Viewer and/or PuTTY (Telnet and SSH client). Furthermore some extra Network Tools, Midori Private Browser, SMTube (YouTube browser which allows to browse, search and play YouTube videos) and PulseAudio for better sound in YouTube. Study all installed packages in RaspEX Build 161019.

The Raspberry Pi 3 is the third generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in February 2016.

Compatibility :: October 2016
Unfortunately not all systems made for Raspberry Pi 2 will run on the new Pi 3. They need to be upgraded with a new kernel. I therefore have to upgrade the systems I distribute. I.e. RaspEX with LXDE, RaspEX with Kodi, RaspEX with OpenCPN, RaspAnd Marshmallow, RaspAnd Lollipop and RaspArch. I have now (161019) upgraded all systems. Read about the new Raspberry Pi 3…

Why shall I use RaspEX?
Eight Operating Systems are recommended by Raspberrypi.org. Among them Noobs, Raspbian (Debian Jessie) and Snappy Ubuntu Core. RaspEX is faster (“fast as lightning”), more useful and more fun to use. (In my opinion). One member at this site thought that running RaspEX (for Raspberry Pi 2) was like running Raspberry Pi on “steroids“. RaspEX Build 161019 and 160426 are (of course) even faster, especially if you run the systems on a Raspberry Pi 3 computer.
