loginctl shows tty instead x11

Hi folks
When I startx my xfce4 desktop from command line (I'm using Slackware-Current)
loginct shows tty.

loginctl show-session 1 --p Type --value
tty

But when I use one display manager, like xdm or sddm for example, it shows
correctly x11

loginctl show-session 1 --p Type --value
x11

The problem is, anydesk and other applications only works in Xorg, and they check this type if is x11 to work, so I can only use these softwares using a display manager (xdm or sddm for example).

But I can't use these displayer manager, because I need autologin, and xdm doens't have it, and sddm has so many dependences to work on for my little server.

Has anyone came into this problem too? how startx xfce4 or other environment with the correctly loginctl session type?

Thanks all in advance.

(Disclaimer: I don't use Slackware and know very little about elogind, but in the absence of other answers...)

Assuming Slackware uses a sufficiently same elogind as in Debian, the relevant logic seems to be in pam_sm_open_session in pam_elogind.c

It looks like if XDG_SESSSION_TYPE is populated, its value will be used, otherwise it is derived from other variables:

Code:

type = getenv_harder(handle, "XDG_SESSION_TYPE", type_pam);

...

if (isempty(type))
   type = !isempty(display) ? "x11" :
      !isempty(tty) ? "tty" : "unspecified";

So if "XDG_SESSSION_TYPE=x11; loginctl ..." gives the desired output, you probably just need to export that variable in an appropriate place.

Hi, It worked! ..but..

First of all setting XDG_SESSION_TYPE before login (/etc/rc.d/rc.local) or after that (and ran startx), didn't work.
What worked was setting this variable in /etc/environment, but all my logins shows Type=x11 even when I didn't start X yet
So it's not the ideal solution.

I managed to skip the login part, and go right through the X and xfce4, so I manually ran the profile scripts, but loginctl shows 'no sessions' now, it's like I didn't have logged in the system (right.) but I didn't manage how to run the same login shell after boot in the terminal.

su doens't work, loginctl still shows no sessions.

So ok, it worked, but it's not a ideal fix.
Thank you for all your help.
