I´ve installed Slackware 14.2 (64bit) on a friends computer.
Booting into runlevel 4.
There is no GDM / KDM installed so using XDM instead as it´s enough.
But i X11 logins are not registered at all.
# Register a login (derived from GiveConsole as follows
exec /usr/bin/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x /usr/lib64/X11/xdm/Xservers -l $DISPLAY -h "" $USER
/etc/X11/xdm/Xserver has just one line "active"
:0 local /usr/bin/X :0 -nolisten tcp
I checked with my setup as i am running XDM too and all those have the same content.
Thanks for any hints.
