Description Jean-Pierre Rupp 2017-06-08 15:53:50 EDT
Description of problem:


Version-Release number of selected component (if applicable):

$ uname -r
4.11.3-200.fc25.x86_64


How reproducible:
Every time I resume from suspended state when docked and lid closed I get that behaviour.

Steps to Reproduce:
1. Laptop is running on external display. Lid is closed. Internal display is not active.
2. Suspend laptop.
3. Resume laptop by using power switch on docking station (do not open lid).

Actual results:
Internal display is now primary, but laptop lid is closed. External display is now behaving as secondary.


Expected results:
When laptop is closed, its internal display should always be off, even when resuming from suspend.


Additional info:
If I open the lid after the laptop resumes, and then close it again, the internal display is finally powered off and the external display becomes the only one, so I do that to correct the behaviour.

The bad behaviour also happened when I disabled Wayland from the GDM configuration and rebooted the computer. Also bad behaviour is independent on whether a user is logged in. Suspending/resuming from the GDM login screen causes the same issue.

The affected laptop is a ThinkPad T450s with a standard IBM docking station and an external Dell display.
