A more thorough guide to installing, configuring, and running wayland on Alpine would be better.


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. There are a few ways to configure this variable:

  • A login manager such as Elogind can configure this and other XDG environment variables automatically.
  • pam_rundir can enable this for logins. To use this PAM is required.
  • Setting it up manually

Configuring XDG_RUNTIME_DIR manually

Generally, care should be taken when configuring the XDG_* variables manually as this configuration may have errors or conflict with other utilities that do this automatically.

On a system that's not using elogind nor any pam module that handles this, it's often necessary to set up XDG_RUNTIME_DIR manually. This can be done by adding a snippet like this one to shell init scripts (e.g.: ~/.profile):

Contents of ~/.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}" fi fi
