Wayland is a new display protocol that aims to replace X11.
XDG_RUNTIME_DIR
As per the protocol spec, Wayland compositors require the XDG_RUNTIME_DIR variable to be set. A login manager such as Elogind can configure this and other Freedesktop.org environment variables automatically.
Generally it's inadvisable to configure XDG_* variables manually as this configuration may have errors or conflict with other utilities that do this automatically.
That said, on a system that's not using elogind/pam, it's often necessary to set up XDG_RUNTIME_DIR manually. This can be done by adding snippet like this one to shell init scripts (e.g.: ~/.profile):
if test -z "${XDG_RUNTIME_DIR}"; then
export XDG_RUNTIME_DIR=/tmp/$(id -u)-runtime-dir
if ! test -d "${XDG_RUNTIME_DIR}"; then
mkdir "${XDG_RUNTIME_DIR}"
chmod 0700 "${XDG_RUNTIME_DIR}"
