Rouven Czerwinski a3a82efbf6 realtime: request SCHED_RR using CAP_SYS_NICE 
Try to gain SCHED_RR (round-robin) realtime scheduling privileges before
starting the server. This requires CAP_SYS_NICE on Linux systems.
We additionally register a pthread_atfork callback which resets the
scheduling class back to SCHED_OTHER (the Linux system default).

Due to CAP_SYS_NICE, setting RLIMIT_RTPRIO has no effect on the process
as documented within man 7 sched (from Linux):

  Privileged (CAP_SYS_NICE) threads ignore the RLIMIT_RTPRIO limit;
  as with older kernels, they can make arbitrary changes to
  scheduling policy and priority. See getrlimit(2) for further
  information on RLIMIT_RTPRIO

Note that this requires the sway distribution packagers to set the
CAP_SYS_NICE capability on the sway binary.

Supersedes #6992

Installation

From Packages

Sway is available in many distributions. Try installing the "sway" package for yours.

Compiling from Source

Check out this wiki page if you want to build the HEAD of sway and wlroots for testing or development.

Install dependencies:

  • meson *
  • wlroots
  • wayland
  • wayland-protocols *
  • pcre2
  • json-c
  • pango
  • cairo
  • gdk-pixbuf2 (optional: system tray)
  • scdoc (optional: man pages) *
  • git (optional: version info) *

* Compile-time dep

Run these commands:

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

On systems without logind nor seatd, 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).
