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
  • wayland-protocols *
  • pcre
  • json-c
  • pango
  • cairo
  • gdk-pixbuf2 **
  • scdoc >= 1.8.1 (optional: man pages) *
  • git *

*Compile-time dep

**optional: required for swaybg

Run these commands:

meson build
ninja -C build
sudo ninja -C build install

On systems without logind, you need to suid the sway binary:

sudo chmod a+s /usr/local/bin/sway

Sway will drop root permissions shortly after startup.

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).
