            Bug ID: 350807
           Summary: Desktop freezes when monitor switched off
           Product: Powerdevil
           Version: 5.3.2
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: plasma-devel at kde.org
          Reporter: danny at ciarniello.ca

When "Screen Energy Saving" is enabled, the desktop freezes when the monitor is
switched off.

The mouse is still active and moving it or hitting a key on the keyboard turns
the monitor back on but nothing (task bar, desktop icons, open windows)
responds to mouse clicks.  

This is on a system recently (2 days ago) updated from Fedora 21 to Fedora 22.

Reproducible: Always

Steps to Reproduce:
1. Enable "Screen Energy Saving" and apply
2. Wait for monitor to turn off
3. Move mouse to turn monitor back on

Actual Results:  
Desktop is frozen

Expected Results:  
Desktop usable

System: Fedora 22
