Description Ralf Jung 2015-09-24 11:20:34 UTC 
The lock screen does not update itself when the screen geometry changes. That can make it impossible to log back in.

Reproducible: Always

Steps to Reproduce:
1. Have an external screen connected to a laptop, and the internal screen turned off.
2. Suspend the machine
3. Plug off the external screen
4. Resume the machine

Actual Results:  
The internal laptop screen shows a cursor, and is all black otherwise.

Expected Results:  
The internal screen should show the lock screen.

This is (another...) regression compared to KDE4.

This could be the same as bug #347934. Could you please check the xrandr output whether the information is correct?

This is really old, with few duplicates. Please reopen if it's still an issue.
