Hi, the Big Deal here is that starting a wayland compositor requires something to provide access to GPU and input devices. The big compositors (GNOME Shell, KDE KWin) rely on logind, which we don't have. For Weston, there is a setuid binary called 'weston-launch' that works. Sway and other wlroots based compositors also have something similar, I forget already. So: - Install libinput from my ports (https://github.com/myfreeweb/freebsd-ports-dank/tree/master/x11/libinput) - Install Weston from my fork (https://github.com/myfreeweb/weston) - Add yourself to the 'weston-launch' group - Make sure the 'weston-launch' binary is suid and owned by root - Make sure you have an 'XDG_RUNTIME_DIR' in the environment - Put your favorite keyboard settings into the environment e.g. 'export XKB_DEFAULT_LAYOUT=us XKB_DEFAULT_VARIANT=colemak XKB_DEFAULT_MODEL=pc101 XKB_DEFAULT_RULES=evdev XKB_DEFAULT_OPTIONS="ctrl:nocaps,ctrl:lctrl_meta,compose:ralt,grp:alt_space_toggle"' - Run 'weston-launch'! The libinput in my ports has this patch https://github.com/myfreeweb/freebsd-ports-dank/blob/master/x11/libinput/files/patch-src_evdev.c.reopen which should fix /dev permissions issues. If that doesn't work, or you decide not to use it, give yourself read+write permissions on /dev/tty*, /dev/input/*, /dev/dri/*, /dev/drm/*.
