Bah, sadly i forgot to check the blanking issue before i updated because now it has returned. Thing is that my N800 had run out of battery earlier, and when i plugged in the charger it booted but then "screen fade" rebooted.

going to try rebooting with alarmd disabled, and then rebooting again with it enabled to see if that shakes something "loose".

Edit: Crap, booting with alarmd disabled had no effect this time. Could it be related to some kind of charging issue?

edit2: bah, no change when booting with charger unplugged.

edit3: shutting down, inserting charger, letting the tablet boot into charging mode, then booting to full desktop made blanking work again. Funny enough the tablet came up with screen locked. Also, alarmd was disabled during all this. Now to enable and reboot.

edit4: blanking works after rebooting with alarmd enabled. But the ASUI battery meter seems a bit confused. It is displaying a 94.5% battery level...
