Description Benjamin Xiao 2015-10-26 17:41:53 EDT
Description of problem:
I have a Lenovo X1 Carbon and a Onelink Pro Dock with two external monitors connected. I have my monitor configuration laid out such that my two external monitors are side by side and my laptop display is right underneath them in the middle. Everytime I undock and redock my laptop, the monitor configuration is reset to defaults. My monitors are laid out in a line and the resolutions are set to native. This issue didn't used to happen until about a month ago.

If I boot the laptop with it already connected to the dock, the monitor configuration is properly restored. The wrong behavior only seems to happen when undocking and redocking the laptop

Version-Release number of selected component (if applicable):
Up to date Fedora 22

How reproducible:

Steps to Reproduce:
1. Connect a Lenovo X1 carbon to a OneLink Pro dock
2. Connect two external monitors to the dock
3. Layout monitor configuration with external monitors side by side and laptop display underneathe in the middle.
4. Disconnect dock
5. Reconnect dock

Actual results:
Monitor configuration is reset to defaults

Expected results:
Monitor configuration should be preserved during redocking

Additional info:

I have not tested this in other multi-monitor configurations without the OneLink Pro Dock, so I am not sure if its hardware specific or not.

I am also having the same issue.

Fedora 22 using Cinnamon on a Lenovo T450s, and a Lenovo dock. I am using the laptop display, and an additional Samsung display. 

After undocking and redocking, my display settings are reset.

Specifically, it forgets the layout of the displays, and forgets that the Samsung is the primary display.
