Now that kdm is gone I need to find a replacement for a feature that I want to use on some systems. Since switching users in KDE never worked for me (either in KDE 4 or now), I used to start several X servers, each on its own VT, each with a greeter. One user could log in on VT9 and another on VT10, etc. They could not work at the same time, of course. But they could time share the computer. This setup was easy with kdm.
Now, I have looked at several still supported DM-s and none of them seems to support that feature. Various Linux documentation talks a lot of multi-seat and I think that what I want is a simpler subset of the multi-seat. But it seems all mainstream DMs support multi-seat only via Linux / systemd based infrastructure like logind / loginctl etc. I could not find a way to explicitly configure multiple X servers on multiple VTs. I guess that I should be able to achieve what I want with xdm and /etc/ttys, but xdm is so ugly... -- Andriy Gapon
