i have an issue with hibernation since some days ago,
whenever i wake my system up from the hibernation, i face a vague and hazy display such the pictures i've attached.
i can move mouse pointer and i go to the text console by pressing ctrl+alt+F2, F3 etc..., but the display doesn't work properly.
PS1: One time (when i faced this issue) i could blindly change 'advanced setting of desktop effect' (changing openGL version) and when it prompted to save or discard setting, the process made xwindow working just fine.
PS2: Having an nVidia GTS 450 (driver version: 325.15), Core2Quad 6600, 4GB Ram / using Mageia 4
PS3: I just simply put the 'Hibernate' button for hibernation,

Any help will be appreciated
Regards
