           Summary: Opening the LID while in standby, wakes up the
                    notebook with the screen powered off
           Product: kde
           Version: 4.4
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: askrym at hotmail.com


Version:           4.4 (using KDE 4.4.5) 
OS:                Linux

i have Kubuntu Lucid 10.04.3 i386 (KDE 4.4.5) installed on a netbook "HP Mini
110-1100SL".

Pushing the combination: Fn+F1 (sleep button) makes the netbook stand by, the
system wakes up normally by hitting enter button.

Everything's fine so far but;

closing the LID instead, makes the netbook stand by, the system wakes up when
the LID is newly opened but the screen remains powered off. (it isn't simply a
black screen, it's actually OFF).
Funny part at this point is that while the system is running and the screen is
OFF; if you close the LID again, the stand by mode does not trigger, and
Opening the LID once more, actually switches back ON the screen.

Finally you have the system working normally again.

There's indeed something wrong with the open/close LID handler event.

Reproducible: Always

Steps to Reproduce:
1) have a netbook/notebook with kubuntu 10.04.3 i386 KDE 4.4.5
2) choose a power saving profile which triggers stand by mode when the LID is
closed
3) close the LID
----the system enters stand by mode------
4) open the LID
------ the system wakes up ----------
5) the screen is not yet ON
6) close the LID again
------the system runs still ------
7) open the LID
8) screen is now ON

Actual Results:  
the screen is still OFF after opening the LID (for the first time) while in
sleep-mode.

Expected Results:  
when opening the LID for the first time while in sleep-mode, the system should
wake up and the screen should turn ON together.
