If you haven’t gone through parts one and two, you should definitely do so before proceeding. In this tutorial we will cover installing the rofi application launcher, installing the polybar toolbar, and doing some additional tweaking to the UI elements.
This is fairly simple. Running “apt install rofi” will get the program installed. Then you just need to edit your ~/.i3/config file. Look for the line “bindsym Mod1+d exec dmenu_run” and replace it with “bindsym Mod1+d exec rofi -show run”. Log out, back in, test it and it and if it works… SNAP THE VM.
Start by installing the pre-requisistes. Run the command “apt install cmake cmake-data libcairo2-dev libxcb1-dev libxcb-ewmh-dev libxcb-icccm4-dev libxcb-image0-dev libxcb-randr0-dev libxcb-util0-dev libxcb-xkb-dev pkg-config python-xcbgen xcb-proto libxcb-xrm-dev libasound2-dev libmpdclient-dev libiw-dev libcurl4-openssl-dev libpulse-dev mpd libxcb-composite0-dev”
Once that is done, download polybar by running “git clone https://github.com/jaagr/polybar.git”, the build it by running “cd polybar && ./build.sh” You will be prompted to determine what you want to install, I just say yes to everything YMMV. Do your homework on that.
To actually turn on polybar, comment out the following section:
status_command i3status -t
Add the following line (possibly adjusting for your system:
exec_always –no-startup-id polybar pyrrh1c &
Once polybar is installed, you will need to configure it. I could write a lengthy tutorial on that… But for the sake of brevity you can just download my polybar config file and look at how it’s set up. This is the one piece I couldn’t reduce to an easy walk through. Basically, just make a folder in your .config folder called polybar, then copy the config file into it.
Install some additional Fonts
Polybar uses some special unicode characters. This doesn’t work well unless you install the appropriate fonts. (mainly siji and unifont) You can install unifont by simply running “apt install unifont”. Install Siji by running the following commands:
git clone https://github.com/stark/siji.git
Once that’s done, add the following lines to your .bashrc file
xset +fp /root/.fonts
xset fp rehash
Compton is a desktop compositor. It basically helps glue things together. To get it running, rust run “apt install compton”, then when it’s done edit your ~/.i3/config file an add the line “exec compton”.At this point your box should look somewhat like the one to the left.
Configure the Exit Sequence to Actually Exit
Edit your ~/.i3/config file. Look for the line “bindsym Mod1+Shift+e exec “i3-nagbar -t warning -m ‘You pressed the exit shortcut. Do you really want to exit i3? this will end you X session.” Change it to “bindsym Mod1+Shift+e exec i3-msg exit”. You will no longer be nagged when you want to exit.:q
That’s all for now. Stay tuned as I may do a more thorough overview for PolyBar at some point. Thanks for reading!
