Thanks for the tips. But looks like it's not my case (or at least I think so): > root@skobkin-pc /etc/X11/Sessions > > # ls -l > total 6 > lrwxrwxrwx 1 root root 5 Aug 9 16:14 Xfce -> Xfce4 > -rwxr-xr-x 1 root root 11 Aug 9 16:14 Xfce4 > -rwxr-xr-x 1 root root 2187 Jul 9 11:05 Xsession > skobkin@skobkin-pc ~ > > $ ls -l ./.x* > -rw-r--r-- 1 skobkin skobkin 72 Apr 2 2016 ./.xinitrc # here's > only two commented lines which I used long ago > -rw-r--r-- 1 skobkin skobkin 8149 Jan 12 2016 ./.xscreensaver > -rw------- 1 skobkin skobkin 189985 Jul 9 2017 ./.xsession-errors > > > $ ls -l ./.X* > -rw------- 1 skobkin skobkin 55 Oct 26 13:25 ./.Xauthority > As a result there were two sessions > starting as shown by ck-list-sessions I don't have ck-list-sessions binary in my filesystem. Looks like it's provided by sys-auth/consolekit which is not installed in my system right now. But I think it was until I moved to the systemd and then made depclean. Also after this I tried to list sessions with loginctl but I've got strange result: > > $ loginctl list-sessions > No sessions. I remember when I used it last time it showed at least one X-session... -- Kind regards, Alexey Eschenko https://skobk.in/
