Mageia forum

it is possible to click on the cogwheel next to the Sign in button in the GDM login screen to choose other display managers installed, IceWm, Plasma etc.
How can I designate a default choice or modify the menu order?
I have done a web search for three days and no solutions apply as suggested files or folders do not exist.

Bog standard stock Mageia 6 + Gnome 3.24.2

The default is the one that was selected last time, this is the same for other login managers.

And the order is determined by the .desktop files which define those sessions, they are contained in /usr/share/xsessions.
I believe the default is they are sorted alphabetically, and I believe you can't change that via some GDM setting if this is what you're asking for.
You would have to change the name properties in the .desktop files.

Thanks, I've already been to that page and many others, <share>/xsessions is empty and the other folders do not exist!

In the the ~/.dmrc file is

[Desktop]
Session=GNOME

but Plasma is always first in the list and the default!

according to https://help.gnome.org/admin/system-admin-guide/3.24/session-user.html.en
/var/lib/AccountsService/users/ there is a username file containing the default desktop choice, for me there is one named MyUserName but it seems to have no effect or be overridden.

Prefixing the files in /usr/share/xsessions like in https://askubuntu.com/a/871568 seems to order the choices like in old .bat boot files

Maybe you should have added that to your initial problem description, if that is the actual issue you're having

So you say if you select another session which is not plasma and login successfully, then logout again, once you're at GDM again if you only provide your username and password it will login to Plasma?

Yup, plasma was always proposed first but prefixing the files works for me; I've put 1-Gnome, 2-Gnome Xorg, etc and as the first is always proposed by default it proposes 1-Gnome and that was my goal. My wife just enters the pwd and hits ENTER, I choose Plasma when I need it, everyone is happy.

Youv'e probably put your finger on a bug in my system, I have a working solution but is the bug serious and needing attention?

Well from your description alone I'm not sure whether this is a bug or whether someone just chose plasma session before you rebooted.
You have to decide whether it's serious or if it needs attention.

Although that you can't configure a default session for different users as described in https://help.gnome.org/admin/system-adm ... er.html.en seems like an issue to me.
Can you show the file that you added as an example ?

edit doktor5000: seems like that the file is being overwritten at logout, see e.g. https://brokkr.net/2016/10/27/setting-d ... lt-latest/
But according to this it should work in general: https://access.redhat.com/documentation ... lt-session
