People "usually" suspend their laptop, so that they can continue their work when they open the laptop. OK! Two choices [GNOME]: 1 - Menu -> Shut Down -> Suspend in this case, the gnome-screensaver locks the PC. but the gnome-screensaver is just a "normal process", and it could be killed e.g.: http://securitytube.net/USB-Autorun-attacks-against-Linux-at-Shmoocon-2011-video.aspx or using any method [video was just an example!!]. 2 - Menu -> Log out -> Switch user -> Suspend in this case, the GDM [???] protects the user [i mean it locks the PC from other users] Which one is more secure/safer? -------------- next part -------------- An HTML attachment was scrubbed...
