Latest changes based off OpenBSD 7.5

Lightweight Desktop installer for OpenBSD based on the suckless philosophy. Includes my own custom set of suckless tools (dwm, slstatus, dmenu, etc.)

What You Get

The Open Suck installer gives you the absolute barebones desktop experience:

  • dwm for window management
  • ranger for your file browser
  • qutebrowser as your core web browser
  • aerc for your terminal-based mail client
  • slock for screen locking
  • scrot/slop for simple screenshot utilities
  • feh for your image/file viewing
  • dunst for notifications


  1. Download the latest OpenBSD iso and follow the installer
  2. Install git, vim, bash
  3. Edit/create doas permissions (/etc/doas.conf):
permit nopass :wheel

Now logout and log back in as your main user.

Clone the main installer project:

git clone https://git.btxx.org/open-suck

cd open-suck


1) Install dependencies by running ./install-dependencies.sh. The script will simply read required packages from dependencies.txt and run pkg_add. 2) Compile and install suckless software by running the ./install.sh


cd open-suck # CD into this repository
doas sh ./install-dependencies.sh # Install OpenBSD packages
doas sh ./install.sh # Install suckless tools
cp .xinitrc ~/.xinitrc # Apply .xinitrc

Reboot the machine. Log in as your main user. Run:


Optimizing OpenBSD

Improving Battery Performance

Properly setup apmd:

rcctl enable apmd
rcctl set apmd flags -A
rcctl start apmd

Setup WiFi

The following assumes you have installed/setup the proper firmware updates for your hardware.

ifconfig iwn0 up
ifconfig iwn0 scan
echo "join WIFI-NAME wpakey PASSPHRASE" >> /etc/hostname.iwn0
echo "dhcp" >> /etc/hostname.iwn0
echo "inet6 autoconf" >> /etc/hostname.iwn0
echo "up powersave" >> /etc/hostname.iwn0
dhclient iwn0

Take note of the iwn0, as this might differ on your machine.

You might also need to run doas sh /etc/netstart after.
