Last night I installed Build 2012-02-18, coming from the original stock OS. The screen backlight no longer dims a few seconds before the screen goes black like it did on stock, and like it does on my Optimus V that is also running CM7, and on another Optimus V that is stock.
How do I get the pre-timeout dimming back? I find it very useful.
And, not as important, since I like my brightness set at about 30% most of the time, and I can adjust it manually if necessary, but is there a way to get the auto-brightness to act more like stock: When I had auto-brightness on in CM7, it seemed to vary brightness very often, which was distracting, and it was a lot more subtle on stock. In any case, I generally only need 3 levels: Lowest, when it's totally dark; 30% most of the time; and 100% in bright sunlight, so if there is a way to set that up, please let me know.
PS: Touch-screen/soft-button response seems a lot better than stock, which is one of the reasons I installed CM7. Thanks.
