Description Oliver Henshaw 2010-10-20 15:31:38 UTC

Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

With "Lock screen on resume" the system resumes from suspend with a blanked screen - I have to move the mouse to see the unlock dialog. This is undesirable because (1) it looks like the resume has failed, (2) the system should be visibly restored as soon as it is fully resumed.

Reproducible: Always

Steps to Reproduce:
Resume from suspend

Actual Results:  
Blank screen (as screensaver)

Expected Results:  
Screensaver unlock dialog

now that i implemented bug 207348, this should be fairly easy to do on the powerdevil side. provided the locker is already running when we wake up ...

Comment 2 Oliver Henshaw 2010-10-23 15:48:23 UTC

I think powerdevil already calls SimulateUserActivity on the resume path (to avoid idling again I think).

FWIW I think that this is how the gnome screensaver/power-manager already behave (but I think in their case SimulateUserActivity does fake an x event so they may get this as a side effect)
