I run Opensuse 13.1 64 bit Gnome Shell 3.10.2. After some period of inactivity the OS attempts to turn off the screen ("blank screen" in power settings), but fails to do so and restarts the OS (or kills the X server or smth like that) - I see the login screen.
Hardware & video: Asus notebook with intel and nvidia gforce 720 m cards; bumblebee installed.
If any logs should be attached to better understand the causes of the issue, please kindly advice which ones. Thank you.
