Alexander Orzechowski 88c17ece3b warp_to_constraint_cursor_hint: Handle NULL view 
This might be the wrong fix, but the crash is happening because the ->data
field on an xwayland surface is NULL. A NULL data field is normal for
unmanaged surfaces, however it seems clients can do weird things: They can
create a cursor lock on a regular xwayland surface then make it unmanaged
by calling override_redirect. In this case, the xwayland server should
destroy the cursor lock, which is does, but does so in the wrong order
making it try to dereference a NULL pointer after sway has acknowledged
its new unmanaged status.

```

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).
