As asked for in bug #359542 here a shorter summary of the problem mentioned there. KScreen fails to (re-)enable displays after docking/sleep cycles. Reproducible: Sometimes Steps to Reproduce: 1. Put Notebook to sleep. 2. Undock from docking station A (internal screen + one external screen). 3. Dock into docking station B (two external screens). 4. Wake-up. Actual Results: Internal display goes on, gets deactivated, external displays do not get even powered on. Undocking does not reactive the internal display. Open data/application states get lost. Expected Results: Internal display should go off but the two external displays should also get activated. DELL E6430 with a mobile nvidia chip. Docking Station A has an horizontal Full-HD display on the DVI port. The internal 1600x900 display LVDS is used. Docking Station B has an horizontal 2560x1440 display on the DP port and a vertical 2048x1152. The internal display cannot be used.

Thanks, much clearer now. Unfortunately, it's nothing I can test or reproduce, as my docking station and laptop can only handle one external monitor, and I don't use NVidia hardware either.
