Bug Description
Environment
Ubuntu 14.04, lightdm, unity
The problem occurs while trying to switch to another running user session. It brings black X screen instead of password prompt window.
Steps to reproduce:
1. Login as user1 //creates X on vt7
2. Switch to new user session for user2 //creates X on vt8
3. Try to switch to user1 session via indicator-session //creates X on vt9 with black screen
This bug is similiar to a bunch of registered bugs related to incorrect file permissions.
But none of advices helped.
I found out that only blacklisting of nouveau kernel module helps
I attached logs from /var/log/lightdm
