The reason I mentioned it (and I should have added this in my post) was that in my case the start up animation and "loading modules" bit was done at MAX BRIGHT and then it switched to using the dimmer settings (MIN). Confused the hell out me - it looked like a faulty display, only a few moments ago it was nice and bright. Then I remembered the dimmer...........
It seems (and i'n not sure if 1.0 had this feature) that there are seperate dimmer settings for both headlight on and headlight off. Both default to 0 on install.
