Description Daniel Pfenniger 2015-09-16 09:43:58 UTC

When connecting the laptop (Lenovo Thinlpad w540) to an external monitor on docking station 
the screen configuration works only after a reboot.  After suspend the configuration is not accepted.  In older versions the dual, triple screen configuration was sometimes automatically detected and remembered.  


Reproducible: Always

Steps to Reproduce:
1. Connect laptop after suspend to the docking station
2. Try to configure with systemsettings (autoconfiguration does not work in any case)
3. Nothing works as expected

Actual Results:  
Poor usability

Expected Results:  
Screen configuration should be automatically detected and remembered for next time. 

This kind of usability bugs has affected Linux laptops as long as I can remember. 
Suspend/hibernate features support are crucial for adopting Linux on laptops.

Perhaps this information may be useful to find why kscreen doesn't detect the secondary screen. 

Using arandr after kscreen I am able to activate the secondary screen.

I have stopped using the docking station, it wasn't worth using it with the remaining problems, but I continue to use the laptop and kscreen, so I cannot confirm whether the problem persists.

Ok, thanks for the info. There's nothing we can do if you're unable to reproduce the original issue.
