AFFECTS: users of x11/libxkbcommon
AUTHOR: zeising@FreeBSD.org
The libxkbcommon library (x11/libxkbcommon), used to handle keyboards
in some applications, most notably kde and wayland, have been switched
to use evdev rules by default on FreeBSD 12 and later. Some keys, most
notably arrow keys, may not work in applications using libxkbcommon if
you are using xf86-input-keyboard rather than xf86-input-libinput.
If you have trouble with the keyboard keys, and if /var/log/Xorg.*.log
shows that the "kbd" or "keyboard" driver is being used, you need toо
switch to legacy rules by setting the environment variable
XKB_DEFAULT_RULES to xorg.
This switch is made to match the default configuration on FreeBSD 12.1 and
later, the default configuration on FreeBSD 11.3 still uses the legacy
rules.
