I've assigned the bug to the linux package too, since this seems more related to the kernel than to X or the gnome-screensaver itself (since the bug is shown also using xset dpms force off).
I'm quite sure it depends on the kernel side, since few months ago I upgraded my maverick kernel with the natty one (just the kernel) and this bug began to manifest. It has still persisted when upgrading also Xorg, libdrm, Mesa and Compiz (yeah... I love hybrid systems :D). So I guess that it's mostly related to it. Could it be related to this: https://bugzilla.kernel.org/show_bug.cgi?id=27312 ? Plus, in my PC I've an hybrid-graphics (Intel + ATi). I actually noticed the bug only when using the Intel i965 card, while with I never got it while using my ATi evergreen card, but to be fair I've to say that I rarely enable this discrete card. ** Bug watch added: Linux Kernel Bug Tracker #27312 http://bugzilla.kernel.org/show_bug.cgi?id=27312 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/762918 Title: Natty Screensaver freezes system after some period of inactivity -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
