Your sway process doesn't have permission to access /dev/input/*.
[re: the little follow-up email: setuid does not help, because input devices are attached after dropping root, because input devices need to be hotpluggable anyway. setuid is bad, use consolekit2 as described below]
The good (but a bit involved for now) fix:
- run 'sysctl kern.evdev.input' to make sure you have a recent enough kernel -- my patch for this is not in 12.0-RELEASE, but should be in 12.1-BETA I'm pretty sure
- build libudev-devd with https://github.com/myfreeweb/freebsd-ports-dank/blob/lite/devel/libudev-devd/Makefile (i.e. update to the latest git commit)
- build consolekit2 with https://reviews.freebsd.org/D18754
- build wlroots with CONSOLEKIT option
- enable automatic CK2 session creation on login: add 'session optional pam_ck_connector.so' to the '# session' section of /etc/pam.d/login
- log out, log in, just run sway
- (you can launch sway under ck-launch-session if the automatic session gets screwed up somehow, but it works for me pretty well)
The bad (but quick) fix:
- chmod/chown /dev/input/* to be accessible to your account
- (there's some devfs config thing that can do this automatically)
- (this exposes input devices to any program running as your account, which defeats the "no keyloggers allowed" advantage of wayland)
