[Bug 1405349] Re: switching to activated guest session causes screen blank
I'm thinking something like unity-settings-daemon should be picking up
that the session has become active and enable the screen.

Bug description:
Hi,
I switch to activated guest session, but the screen remains blank. I have to wake it up with keyboard/mouse action.
How to reproduce:
1. login with your account normally.
2. switch to guest session from the panel menu "Switch Account... -> Guest Session", now it's under guest session and the display is normal.
3. switch back to your user account, then switch to guest session again.
4. The screen remains blank.
I can't reproduce this issue under Precise.
Vivid snapshot 22-Mar-2015 can also reproduce this issue.
Package:
lightdm 1.10.3-0ubuntu2
