I have installed the 12.10 beta (with all updates) on my iMac Early 2008. One annoying problem I'm having is that, when I log out of my account and go back to the login screen (lightdm, per default), the screen stays on: it never goes blank. This is not good for my display I guess!

The screensaver (set to just a blank screen) works just fine when I'm logged in. The problem only appears at the login screen.

Any ideas?


Unless you are using an old CRT screen, no harm will be done to your display. LCD displays do not need screensavers.

  • Thanks... I would still feel more comfortable if my screen went blank though. Also, I assume it saves some power, no? – Marciano Siniscalchi Oct 19 '12 at 15:21
