"SirCmpwn's Wayland compositor" is a work in progress i3-compatible Wayland compositor. Read the FAQ. Join the IRC channel (#sway on irc.freenode.net).

Notice: You are viewing the unstable and unsupported master branch of sway, where work is ongoing to port it to wlroots. The supported branch is the 0.15 branch, and end users are encouraged to use the stable releases cut from it.

If you'd like to support sway development, please contribute to SirCmpwn's Patreon page.

Release Signatures

Releases are signed with B22DA89A and published on GitHub.

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)
  • ffmpeg (required for video capture with swaygrab)
  • scdoc (required for man pages)

*Only required for swaybar, swaybg, and swaylock

**Only required for swaylock

***Only required for tray support

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).
