Description Ladislav Jozsa 2016-12-07 08:45:01 UTC
Description of problem:

when I configure my system to use 3 screens, basically 2 LCD's connected to T450s docking station via DVI and VGA and 3rd screen is T450s then after some time environment completely freezes and I'm unable to even switch to console using ctrl-alt-fx shortcuts.

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

How reproducible:
after some time of using 100%

Steps to Reproduce:
1. Use Lenovo T450s with integrated GPU only and docking station
2. Connect two LCD's to the docking station
3. Configure system to use all 3 screens (incl. laptop screen)
4. Work with the system for a while
5. To help to trigger the freeze try to play some youtube video while reconfiguring screen setup (making one primary, other secondary, etc)

Actual results:
Complete freeze of the environment

Expected results:
