Public bug reported: Often, waking the computer up from suspend will cause the screen brightness to be set right down (was 100% before suspend, becomes ~ 20% after waking). This happens during 40-70% of all suspends. I have not yet been able to figure out any correlations with previous activity, so the behaviour seems random.
(I assume this is a LightDM problem, because it first manifests itself in the login screen, but I'm not sure.)
