Installation
From Packages
Sway is available in many distributions. Try installing the "sway" package for yours. If it's not available, check out this wiki page for information on installation for your distributions.
If you're interested in packaging sway for your distribution, stop by the IRC channel or shoot an email to sir@cmpwn.com for advice.
Compiling from Source
Install dependencies:
- meson
- wlroots
- wayland
- xwayland
- libinput >= 1.6.0
- libcap
- pcre
- json-c >= 0.13
- pango
- cairo
- gdk-pixbuf2 *
- pam **
- dbus >= 1.10 ***
- imagemagick (required for image capture with swaygrab)

Run these commands:
meson build
ninja -C build
sudo ninja -C build install
On systems with logind, you need to set a few caps on the binary:
sudo setcap "cap_sys_ptrace,cap_sys_tty_config=eip" /usr/local/bin/sway
On systems without logind, you need to suid the sway binary:
sudo chmod a+s /usr/local/bin/sway
Configuration
If you already use i3, then copy your i3 config to ~/.config/sway/config and
it'll work out of the box. Otherwise, copy the sample configuration file to
~/.config/sway/config. It is usually located at /etc/sway/config.
Run man 5 sway for information on the configuration.
Running
Run sway from a TTY. Some display managers may work but are not supported by
sway (gdm is known to work fairly well).
