Description Fabian Vogt 2017-05-18 15:02:36 UTC

+++ This bug was initially created as a clone of Bug #1030873 +++

If no default autologin session is defined, default.desktop (usually in /usr/share/xsessions, but can eventually be in wayland-sessions as well) is used by displaymanagers such as lightdm and sddm.

This link is now created by update-alternatives for IceWM, Xfce, LXQt (sr not accepted yet), Plasma5 and enlightenment.

This means that if GDM is used if one of those is installed, it will list default.desktop twice, as it is a symlink to a .desktop file in the same directory.

lightdm and sddm are patched to recognize this properly.

GDM should respect the default.desktop selection if nothing else is defined in /etc/sysconfig/displaymanager.

GNOME should also register itself with update-alternatives, with the same priority as KDE (25), for reference: https://build.opensuse.org/package/rdiff/KDE:Frameworks5/plasma5-session?linkrev=base&rev=108

Is another bug report https://bugzilla.gnome.org/show_bug.cgi?id=773371 related to this？
I have installed both GNOME and iceWM. GNOME was chosen during the system installation, but iceWM came with it.
So if I try to enable autologin with GNOME on x.org, it behaves like the bug I mentioned above. Removed iceWM, GDM autologin becomes normal.

No, that is unrelated - the default.desktop implementation is kinda specific to openSUSE in this case (wayland over X is prference in GDM, and default.desktop won't change that)

That one CAN be related, yes - depending on how the setup was installed (if the user did not chose GNOME Desktop in the role selection, then yast leaves' default' in the WM choser, which would then pick icewm, as gnome-shell does not (yet) register as default handler...
