In this tutorial we will cover installing i3-gaps, the urxvt terminal emulator, feh, wal, and rofi. It’s assumed you went through part 1. If not, you may want to go read that now.
I’m not a fan of re-inventing the wheel. There’s a wonderful how-to for installing i3-gaps on Ubuntu that works well for Kali. Head over and follow it, then come back… Done? Great. Now reboot. At the log in screen enter the username, then after hitting next you’ll see a gear.
You’re now logged into the i3 window manager. This is a different world than most window managers. You will be very VERY well served by learning the basic commands and what they do. Take a few minutes to go over the i3 Reference Card and learn how to open up new terminal windows.
So you have probably noticed the ugly red error message by now. That’s a result of the I3 Status bar being referenced, but not installed. There are several options available for status bars (the i3 bar, polybarm lemon bar, etc.) in this series will just add the basic status bar for now. Maybe the polybar later. We’ll see.
So go ahead and open a terminal window with (usually by hitting [alt] + [enter]) and entering the following command: apt install i3status. Once that’s done log out ([alt] + [shift] + [e]) and back in. You should now see the red/white/green status bar. i3 is now ready to go in its most basic form.
Replace the default console app with URXVT
The default terminal doesn’t offer much flexibility so I like to replace it. My terminal of choice is URXVT. Install the URXVT terminal by running apt install rxvt-unicode.
Take a Snapshot!
Things are about to start getting messy. Snapshot now or proceed at your own peril. 😉
Make i3 the default terminal
I’ll assume you know how to edit text files in Linux. If not, here’s a link to using vi. I won’t lie though, if you are trying to Rice Kali Linux, and you don’t know how to edit a text file, I genuinely wonder how you ended up here. 😉
Anyway, edit the i3 config file which is ~/.i3/config. In there, find the line “bindsym Mod1+Return exec i3-sensible-terminal” and replace it with “bindsym Mod1+Return exec /usr/bin/urxvt”. Once it’s saved exit out of all terminal windows and reload the i3 config by pressing [alt]+[shift]+[r].
Remove the URXVT Scroll Bars and Apply Transparency
Create the file ~/.Xdefaults, and in it enter the following line to get rid of the scrollbar and apply transparency:
URxvt*scrollBar: false (NOTE THE CAPITAL “B”!!!)
Install feh to Add a Wallpaper
Download a wallpaper you like, and save it somewhere easy to access.
(I’ll leave how you download it up to you…) I usually put it in /wallpapers and name it wallpaper.png or something similar. Install feh by running “apt install feh” Once it’s done edit your ~/.i3/config file to add the line exec –no-startup-id feh –bg-scale ‘/wallpapers/wallpaper.jpeg’ You now have a scaled background each time you log in. That said, the text is kind of an odd color. Let’s fix that.
Install and Configure PyWal
Running feh without pywal can make for some ugly (and possibly unusable) color schemes for the terminal. To fix that we use PyWal. Install Python3-pip by running “apt install install python3-pip”, then install pywal running “pip3 install pywal”. Once that’s done, add the following lines at the end of your .bashrc (according to the documentation you should put this in the .i3/config file but it NEVER LAUNCHES FOR ME!!!)
wal -i /wallpapers/wallpaper.jpeg
Tighten up Those Gaps!
The tutorial is good, but I prefer a smaller gap.
So edit your ~/.i3/config file and update the following lines:
gaps inner 10
gaps outer 0
We made some serious progress here. We installed i3, the i3 status bar, URXVT, feh, and PyWal. We also configured some transparency and colors. Stay tuned for Part 3 where we’ll dig a little deeper and install rofi, polybar, and other fun stuff!
