Going to sleep in clamshell mode -> wake up in laptop mode #407

Description

I normally use my laptop in clamshell mode (i.e closed lid, connected to an external monitor) monitor so I have defined three autorandr two support various scenarios:

  • laptop-only
  • external-only
  • dual-screen

This mostly works great but here's is the scenario it almost always fails at: I'm in external-only mode and put the machine into sleep. Later I disconnect it from the laptop (to take it out with me) and then later open the lid to wake it up. Autorandr seems to think that I'm in dual-screen mode and then fails to apply the profile. I end up in the previous mode (external only) and don't see anything on my laptop screen 😬

Here's the systemd log showing sleep in dual mode and waking up next day in laptop only mode:

Is this some sort of race condition?
