How I install my system with i3, cryptsetup and netinst of Debian 10 Buster

I use 5partitions:

  • One not encrypted in EXT4 for system (programs, etc) mounted in /
  • One encrypted for user files in EXT4 mounted in /home
  • One encrypted for logs in EXT4 mounted in /var
  • One encrypted for temporary files in EXT4 mounted in /tmp
  • A last one encrypted for swap

1. Copy previous user files

After have partitioned my hard like it’s explained in the above tutorial, I copy content of my last backup of /home folder to the /home partition:

sudo cp -r --preserve=all <backup> <home part.>

2. Install Debian

I install Debian with the “netinst” image. When the installation ask me what I’d like to install (like desktop, etc), I check nothing (except the printer server in fact).

3. Install sudo command

By default, sudo is not installed with Debian. So I do:

apt install sudo
usermod --append -G sudo authmane512

To avoid having to write my password every 10 minutes, I add below line in sudoers file:

Defaults        timestamp_timeout=240

It’s means that I will have to enter my password every 240 minutes…

Before that, make sure the default editor is not an editor that you don’t know:

sudo update-alternatives --config editor

So after launch sudo visudo , you should see:

# This file MUST be edited with the 'visudo' command as root.
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
# See the man page for details on how to write a sudoers file.
Defaults env_reset
Defaults timestamp_timeout=240
Defaults mail_badpass
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
# Host alias specification# User alias specification# Cmnd alias specification# User privilege specification
# Allow members of group sudo to execute any command
# See sudoers(5) for more information on "#include" directives:#includedir /etc/sudoers.d

To make changes effective, logout and login again.

4. Install Fish Shell

Here’s a tutorial:

5. Install some basic utilities

sudo apt install vim ssh man nano less git tmux openssh-server locate make build-essential rsync tree psmisc

Because I very often use Vim with root, I configure it for that:

sudo ln -s /home/authmane512/.vimrc /root/

I do same with Git and Fish Shell:

sudo ln -s /home/authmane512/.gitconfig /root/
sudo ln -s /home/authmane512/.config/fish/ /root/.config/fish/


sudo apt install python3-pip
sudo pip3 install trash-cli

To remember that I mustn’t use rm command, I add this in my .config/fish/ file:

alias rm='echo "This is not the command you are looking for."; false'

NTP server

sudo apt install ntp
sudo systemctl enable ntp
sudo systemctl restart ntp

EDIT: It seems that GNOME already do it without having to enable ntp service.

Suspend and hibernate

To use pm-suspend and pm-hibernate commands:

sudo apt install pm-utils

To be able to suspend my computer without having to enter my password, I add this line to my sudoers file:

authmane512 ALL=(ALL) NOPASSWD: /usr/sbin/pm-suspend

Remember that to modify the file, you must use this command:

sudo visudo

6. Configure cryptsetup & fstab

To access to my encrypted files, I have to install cryptsetup with LVM and modify /etc/fstab and /etc/crypttab files.

sudo apt install lvm2 crypttab

Here’s content of my /etc/fstab

In /etc/crypttab, I just add:

mycryptedvol UUID=<UUID> none luks

none means that password will be asked at computer startup.

To get the 3 UUID, I use blkid command. There is one UUID for my FAT partition, one for the system partion and one for the cryptsetup partition.

Before reboot, I have to move content of /var in the /var partition and then empty the /var and /home folders. We can do it with the rescue mode of the Debian “netinst” image. It asks automatically password of the encrypted partition.

mount /dev/mapper/MyVG-varLV /mnt
cp -r --preserve=all /var/* /mnt/
mv /home /home.backup
mv /var /var.backup
mkdir /home
mkdir /var

Don’t forget to be sure that /var partition is empty before copy anything inside!

7. Install i3 and some graphical programs

sudo apt install i3 dmenu i3lock feh xserver-xorg xinit gksu terminator evince nemo diodon file-roller qalculate network-manager-gnome gthumb xfce4-session

Evince is a document viewer, Nemo a file manager, Diodon a clipboard manager, File Roller an archive manager. It is necessary to reboot after installation to make Terminator working.

Know that the command to open network manager is:


And to open the network connections editor, it’s:


Configure i3

You can get my config files here:

Install i3blocks

i3blocks is a flexible status line for the i3 window manager. We can install it like this:

sudo apt install ruby-ronn sysstat make gcc lm-sensors alsa-utils
git clone git://
cd i3blocks
make clean debug
sudo make install
cd ..
rm -rf i3blocks

To use it, I need to install Awesome and Entypo fonts. I put them in /usr/local/share/fonts:

sudo mv entypo.ttf /usr/local/share/fonts/
sudo mv fontawesome.ttf /usr/local/share/fonts/

It’s necessary to restart after that. I also need the acpi command to get battery state:

sudo apt install acpi

Crow Translate

I install the latest release from:

Then I configure qt5ct:

$ qt5ct

Note: It may be necessary to install these dependencies


I add below line to /etc/apt/sources.list :

deb sid main contrib non-free

Replace ch by letters of your country.


sudo apt update
sudo apt install -t sid firefox

With Firefox, we have to install below package to make sound working:

sudo apt install pulseaudio

Sublime Text 3

It’s explained very well how to install it here:

Note that it’s necessary to install apt-transport-https because the Sublime Text repository is in HTTPS.


I download IntelliJ from website:

cd /opt
sudo tar -xf ideaIC-2018.2.1-no-jdk.tar.gz
sudo mv idea-IC-182.3911.36/ idea
sudo ln -s /opt/idea/bin/ /usr/bin/idea
sudo apt install openjdk-8-jdk # not headless version!

IntelliJ will ask automatically to import previous settings.

I also remove files or folders that I don’t need.

KeyPass XC

I’ve made this tutorial:

8. Configure GTK 2 and 3

To make my system less ugly, I install a GTK theme. For example:

sudo apt install murrine-themes

I have to configure for both Gtk 2 and 3. So, in /etc/gtk-2.0/gtkrc , I put:

gtk-theme-name = "MurrinaBlue"
gtk-font-name = "Open Sans 10"
gtk-icon-theme-name = "MurrinaBlue"

And in /etc/gtk-3.0/settings.ini :

gtk-theme-name = MurrinaBlue
gtk-font-name = Open Sans 10
gtk-fallback-icon-theme = MurrinaBlue
gtk-icon-theme-name = MurrinaBlue

9. Install missing firmwares

I’ve made an article here:

On my laptop, the following was missing:

sudo apt install firmware-iwlwifi

I also needed to download another firmware from Github:

sudo mkdir /lib/firmware/brcm
sudo mv BCM20702A1-0a5c-21e6.hcd /lib/firmware/brcm/

To be able to use my Wi-Fi USB adapter:

sudo apt install firmware-realtek

It is necessary to reboot after installation of those firmwares.

10. Others


$ sudo apt install resolvconf
$ sudo systemctl start resolvconf.service
$ sudo systemctl enable resolvconf.service
$ sudo systemctl status resolvconf.service

Edit content of /etc/resolvconf/resolv.conf.d/head :



$ sudo systemctl restart resolvconf.service
$ sudo chattr +i /etc/resolvconf/resolv.conf.d/head
$ cat /etc/resolv.conf # for checking

Enable tap to click on touchpad

We need to install:

sudo apt install xserver-xorg-input-libinput

We also have to be sure that xserver-xorg-input-synaptics package is not installed:

sudo apt remove xserver-xorg-input-synaptics

Then, I add below content in /etc/X11/xorg.conf :

Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "Tapping" "on"

After that, quit and reopen your graphical interface, in this case i3.

Edit: Finally, I found that modify /etc/X11/xorg.conf file give me some problems… So I use another solution now.

We need to know the device of our touchpad:

$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint

We can easily guess that it’s “SynPS/2 Synaptics TouchPad”. We can then find the right property to enable tap to click:

$ xinput --list-props "SynPS/2 Synaptics TouchPad"
Device 'SynPS/2 Synaptics TouchPad':
Device Enabled (150): 1
Coordinate Transformation Matrix (152): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
libinput Tapping Enabled (287): 0
libinput Tapping Enabled Default (288): 0
libinput Tapping Drag Enabled (289): 1
libinput Tapping Drag Enabled Default (290): 1
libinput Tapping Drag Lock Enabled (291): 0

It’s “libinput Tapping Enabled”. To enable tap to click once, do:

xinput --set-prop "SynPS/2 Synaptics TouchPad" "libinput Tapping Enabled" 1

To enable it permanently, I add below line to my i3 config file:

exec --no-startup-id xinput --set-prop "SynPS/2 Synaptics TouchPad" "libinput Tapping Enabled" 1

Kernel parameters

I open /etc/default/grub and I put:


noresume is to prevent my system trying resume. Because it always do that uselessly and startup becomes slower…

Then I do:

sudo update-grub


sudo grub-mkconfig -o /boot/grub/grub.cfg

Configure my second graphic card

Control luminosity

To control luminosity of my screen, I need this program:

sudo apt install xbacklight

To configure it, I have to find the backlight folder in /sys/ :

sudo find /sys/ -type f -iname '*brightness*'

On my Lenovo Thinkpad T430, it’s:


So I open /etc/X11/xorg.conf and I put:

Section "Device"
Identifier "Card0"
Driver "intel"
Option "Backlight" "/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight/"

After that, I restart graphical interface.

Edit: Finally, I prefer not to modify /etc/X11/xorg.conf and rather use a command like:

echo 4400 | sudo tee /sys/class/backlight/intel_backlight/brightness

Edit 2: I made a keyboard shortcut with i3 to change this file automatically. To makes this possible, I need to make the file reachable to non root users:

sudo chmod 666 /sys/class/backlight/intel_backlight/brightness

Increasing the amount of inotify watchers

echo fs.inotify.max_user_watches=32768 | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

Edit my hosts file

git clone
sudo ln -s /home/authmane512/misc/myhostsfile/hosts /etc/hosts
