    Default screen flickers after turning off

    hi there
    i am a new user of opensuse, coming from ubuntu.
    i am using opensuse 13.1 KDE and i have noticed one thing: i setup my screen to turn off after 2 minutes. after the screen is turnd off, one minutes ahead, the screen flickers once for a split second, after that, after another one minutes, the screen flickers again once for a split second. and after that, nothing is going on, the screen remanins turned off.
    why is this happening? here is my lspci:

    Default Re: screen flickers after turning off

    What output do you have for:
    Code:
     /sbin/lspci -nnk | grep VGA -A2
    What info do you have in the xorg log when this happens?

    What info do you have in the kernel messages when this happens?
