I reproduce on my laptop, but not on some of my other machines. I can actually watch the screensaver attempting to activate every 5 minutes (my timeout), and I have "Blank Screen" selected as my screensaver.
I can set my laptop in the corner and watch it fade to black over a second or two, as soon as the display gets to black, it immediately turns back on. -- screensaver doesn't activate https://launchpad.net/malone/bugs/37555 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
