Red Hat Bugzilla – Bug 1460782
Dual-monitor arrangement and primary monitor change when undocking and docking laptop
Last modified: 2017-06-12 13:31:35 EDT
Description of problem:
I'm running Fedora 25 on a Lenovo ThinkPad T460s. I have it docked in a ThinkPad Ultra Dock which is connected via DisplayPort to an HP Compaq LA2206x monitor.
When I undock and then dock my laptop, the video layout may reset. I want to have an over/under setup with the external monitor appearing above my laptop, and the external monitor should be the primary. I can set that up and it functions just fine until I undock. When I dock, the layout may change and the primary monitor may also change.
Version-Release number of selected component (if applicable):
Almost every time
Steps to Reproduce:
1. Set up desired monitor layout (external monitor above the laptop monitor, set external monitor as primary)
2. Undock the laptop and do some work away from the desk
3. Dock the laptop
Screen layout changes to side-by-side and the primary may or may not switch back to the laptop screen.
Restore the previously set up docked configuration when docking the laptop.
