Artful kills desktop session with external monitor

by Magicloud   Last Updated January 15, 2018 04:02 AM

Just installed Artful on my Dell XPS 9343 with hdd wiped. It was Xenial and fine.

When it is just the laptop (internal monitor), I see no problem.

But if I connected my external monitor and locked the screen, sometimes, when I trying to unlock, it appeared that my session was killed.

What I see:

  1. Monitor is powersaving.
  2. Hit keyboard.
  3. Screen flashes once.
  4. Login screen appears.
  5. Login with the same user.
  6. Lock screen appears.
  7. Input password.
  8. Get back to desktop, all windows gone.

Is there something I configured wrong?
