Xubuntu Wallpaper by Anna Ceccarelli

It’s very easy today to build a complete Linux workstation using the distribution you like best. It seems that the first place is occupied by Ubuntu or derivatives with a percentage of over 30%.

Both the operating system and most applications are free. The most important: such a system is extremely stable, constantly updated, and does not have the known problems with viruses that other operating systems face. However, the market share is 2% with a slight upward trend.

I have been using Linux workstation for over 10 years, Archlinux, and (X)ubuntu. In recent years I prefer Xubuntu because it is simple, elegant and lightweight. Every installation is increasingly easy, complete, stable, and fast. It is a great pleasure to use it.

I am trying to keep my system stable and clean. Only the necessary packages are installed. When it is possible, I use:

  • portable versions (portable VScode is a great example)
  • appimages (see Summary)
  • containerization (offered by docker)

I use apt-get in most install or update commands. Probably apt is more convenient for the user. There are some differences but not so significant.

The whole system is updated using apt package manager. There are some exceptions, mentioned in the Summary.

I use free and open-source software to build my workstation. The only exceptions are:

  • Google Chrome (free but not open-source)
  • Microsoft Edge for Linux (free but not open-source)
  • Dropbox (free Linux client but not open-source)
  • Sublime Text (not free and not open-source)
  • DbSolo (not free and not open-source). DbSolo, it is the only app I know to easily compare and synchronize database schema and this is the reason I use it.
  • jDiskReport (free but not open-source)
  • HDsentinel (free but not open-source)

Linux workstation – Hardware

Here is the hardware configuration of my workstation computer:

  • LG W2453SQ 24 LCD Monitor (1920 x 1080)
  • UPS APC Back UPS BR1500GI RS 1500VA (LI)

Partitions

Basic OS Setup

Download Xubuntu 20.04 LTS ISO from the official website.

Setup using CD or USB device.

System update

Software updater will notify you that software updates are available. Proceed with update.

TO do it manually

sudo apt-get update && sudo apt-get -V upgrade

Mount data drives

Xubuntu is installed in sda1 and sda2. Thers is one more partition in first disk (sda3). This must be mounted. The same for the second disk (sdb).

As root get the partitions UUIDs using

1
blkid

Then update properly /etc/fstab and reboot.

Ksnip is a Qt-based cross-platform screenshot tool that provides many annotation features.

Xubuntu has its own Screenshot tool. It is simple to use. It also has useful keyboard shortcuts: press the PrintScreen to capture the whole screen or ALT + PrintScreen to capture the active window.

git tools

Git cola is an integrated git GUI:

  • excellent commit interface (including revert, diff and merge)
  • log viewer (DAG) / file browser
  • actions: clone, push, pull, tag, stash

It uses external tools for

  • visual diff and merge (Meld, xxdiff or any other)
  • history (gitk)
  • blame (git gui)

Git cola offers to more tools

  • View ➙ DAG (directed acyclic graph) for git log
  • View ➙ File Browser to get the versions on any file (using gitk)

For this purpose, Giggle is more convenient:

Giggle is a graphical frontend for the git content tracker (think of gitk on GTK+).

Use Giggle to:

  • view the full git log (and changes per each commit) (HISTORY mode)
  • get the versions on any file (BROWSE mode)

Finally, VSCode has excellent git integration. However, git cola is more advanced (in commit and more).

LT Browser

LT Browser by LambdaTest – Mobile View Debugging On 45+ Screen Sizes

Use official appimage.

docker

Docker is a tool to create and run applications using containers.

Detailed setup instructions here.

Add yourself to group docker

1
sudo usermod -aG docker yourusername

Unfortunately, you have to logoff and login again (some workarounds are available, but this the simplest way).

Additionally, install Docker Compose. Instructions here.

1
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

To install a different version, substitute 1.26.2 with the version of Compose you want to use.

In addition to my own custom containers, I also use ready-made ones:

Doxygen

Doxygen is a documentation generator

1
sudo apt-get install doxygen-gui graphviz

Doxygen GUI executable is doxywizard (create relevant menu launcher)

Virtualbox

Virtualbox is a cross-platform open-source virtualization solution by Oracle.

It is available from both Oracle and Ubuntu repositories. Oracle repositories contain always the most recent version (at this time 6.1.12 r139181 (Qt5.12.8)). So, I prefer the Oracle solution:

1
sudo nano /etc/apt/sources.list.d/virtualbox.list

add the following line

1
deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian focal contrib

Then import the Oracle key

1
wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -

Then, install the current version

1
2
sudo apt-get update
sudo apt-get install virtualbox-6.1

Add yourself to vboxusers group

1
sudo usermod -aG vboxusers yourusername

Logout and login for this to take effect.

Finally, install Extension Pack:

  • get the most recent package from https://www.virtualbox.org/wiki/Downloads (it must be the same version with Virtualbox, at this time 6.1.12 r139181)
  • Open Virtualbox manager ➙ File ➙ Preferences ➙ Extension ➙ press Add button and install the file you have just downloaded

Set Default Machine Folder from File ➙ Preferences ➙ General

Remember to update Virtualbox Guest Additions in all virtualboxes.

In addition to my own custom virtualboxes, I also use ready-made ones:

Recovery mode

Press and hold “SHIFT” key during boot. GRUB (boot loader) menu will display. Select “Advanced Ubuntu Options” to enter Recovery mode.

For advanced users, it is recommended to display Grub menu always. So you will have easy access to Recovery mode or memtest86+ in case your computer becomes unstable.

To do this change Grub configuration

1
sudo nano /etc/default/grub

make the following changes

1
2
3
GRUB_TIMEOUT_STYLE="menu"
GRUB_TIMEOUT=10
GRUB_CMDLINE_LINUX_DEFAULT=""

update Grub

1
sudo update-grub

and finally reboot your system.

Recovery media

It is recommended to keep recovery media (CD or USB). A multiboot USB is an excellent solution for this purpose. Read this post for details. Recommended recovery media are:

With SystemRescueCd you can perform almost any administration task in case of emergency. For example:

With CloneZilla you can create and restore partition images.

Rescuezilla is similar to Clonezilla, but much simpler. Clonezilla and Rescuezilla images are compatible. Additionally, Rescuezilla offers an Image Explorer with which you can easily mount the image. Image Explorer is slow with big images. A nice tip is to create Clonezilla images without compression. These images are mounted instantly with Rescuezilla Image Explorer. Rescuezilla is in active development.
