There has been a refactoring of the old 'xdm' init script into a new
script called 'display-manager', provided by a new package that will
be introduced by your @world update routine as a dependency of
The package is now in ~arch and will be available to stable users
starting with 2nd March 2021. 
Its purpose is to provide the same startup mechanism for your chosen
display manager (like GDM, SDDM etc. ) as xdm did previously, but
without depending on x11-base/xorg-server. This is necessary to
support new DMs that no longer depend on Xorg.
Existing settings from /etc/conf.d/xdm will be migrated to new
/etc/conf.d/display-manager config, however after installation it is
vital not to forget to run either `etc-update` or `dispatch-conf`.
Afterwards check that /etc/conf.d/display-manager contains the
desired value for DISPLAYMANAGER.
The old 'xdm' init script is no longer supported and henceforth
removed from x11-base/xorg-server-1.20.10-r1, so it is imperative that
you switch from xdm to display-manager service in default runlevel:
# rc-update del xdm default
# rc-update add display-manager default
The changes are complete and on the next reboot, 'display-manager'
will start your chosen DM.
To switch to the new script without rebooting, run the following
commands in a tty:
# rc-service xdm stop
# rc-service display-manager start
Finally, the following action is necessary *ONLY* if you are running
a) a DM (and rest of system) without Xorg
b) a DM from an overlay, to make sure display-manager persists
# emerge --noreplace gui-libs/display-manager-init
 To make this change *now*, and proceed with this news item already,
stable users would need to add the following entries to
/etc/portage/package.accept_keywords  and update @world:
