Description Denis de La Fortelle 2014-08-14 11:34:21 UTC

In the course to reducing a box to MATE + LightDM + systemd with no trace of gdm, I used the following commands :
   emerge --deselect gdm
   emerge --depclean -a
and I had the surprise to have all the graphics stack packages proposed for removal.
After some thinking, I have done :
   emerge --noreplace xorg-server
   emerge --depclean -a
and this time the list of package proposed was OK for me.

Digging a bit in the xdm and lightdm ebuilds, I found no trace of dependency to xorg-server. It seemed to me that the gdm et kdm depend effectively upon xorg-server.

I suggest to add at least to the xdm and lightdm ebuilds a dependency to xorg-server.

I might be wrong.

The thing is, neither display manager actually needs a locally installed display server.  Whether to have the display server on the same system is a decision for the system administrator to make.

Comment 2 Denis de La Fortelle 2014-08-17 20:21:22 UTC

This system administration decision could be made dynamically, as an exemple through a /etc.conf.d/ parameter, or statically through a package USE flag.

The last way seems easy, just add a new USE flag "notlocal" and a line in the ebuild RDEPEND like :

    !notlocal? ( x11-base/xorg-server )

I might be wrong (TM).
