Hello.


I have installed Daedalus-preview, and have noticed, that it does not
let me open second X-session (from another TTY), when there is already
one X-session is opened (from one TTY). Before firing a bug, i wanted
to counsel here -- may i have missed something, and now it is intended
system behaviour.

In the X lof file i get the following corresponding errors:

[ 5304.581] (II) seatd_libseat init
[ 5304.582] (EE) [libseat/backend/seatd.c:308] Could not poll

May, others have no such a problem on Daedalus? -- Please respond. Or,
may you have solved the problem, then, please share how you did it. --
Right from istallation i had to a user to video group and install seatd
package, by the way, -- or the user could no run x-session, or return
to it once switched to console and back. Now i still have same
bahavior, but much rarely. Sometimes, not only impossible to switch
back (from other TTY) to the only x-session, but also seems keyboard
stops functioning, yet "Sys Rq" key works.
