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.

Release Signatures
Releases are signed with E88F5E48 and published on GitHub.
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).
