Experiencing it on Ubuntu 14.04, lightdm 1.9.6
Steps to reproduce
1. Login as user1 (starts session on vt7)
2. Switch to user2 (starts session on vt8)
3. Try to switch to user1 session.
Attempt brings to black X screen (just cross mouse pointer). It seems lightdm starts X only on vt9.

Thus, there are three X terminals (vt7, vt8, vt9).
Switching to another user is possible via manual ctrl-alt-f[7-8] only
Attempt to switch via indicator-session always brings to vt9
