I find the dimmest screen toggle still too bright. I find it embarrassing to use in dark public spaces.
Is there a way to dim the screen even more?
Download the screen filter app from the play store. Literally puts a filter effect on the screen to make it appear darker making it much easier to use in the dark.
Yes its possible to take the screen much lower, but we have to edit the framework. Nobody had done this mod yet for some reason.
CM9 has the ability to change the screen lowest settings built in

+1. I use Screen Filter also, it's uber handy for reading at night when the light seems too bright. If you've got hardkeys like I had on my Desire, you can even turn them off.
i wrote a tutorial on how you can mod the frameworks apk. it's very easy and you can change the brightness levels to anything you want. here's the thread
screen filter only puts a transparent layer on the screen and messes with the colors. modding the frameworks will lower default brightness to any level you want. you can raise it too if you like.
Thanks for all the ideas. I went with the easiest one, Screen Filter.
AOKP also has an option to reduce screen brightness...

Great work, I've been wondering why nobody did this mod yet for the nexus. I made that same mod on my atrix, using the sgs2 thread as well. But I've been too lazy to do it for nexus.
The above mod is the best option. Screen filter doesn't achieve the same results. The above mod reduces power draw as well when on the lower brightness setting of 5 or so. Screen filter just hides the higher brightness but has same power draw.

That would be correct for back-lit screens. For the Galaxy Nexus screen, though, Screen Filter does help reducing power draw as a darker screen content = lower brightness.
I used to use SF for quite a while until I got fed up of it causing stutters to most animations. After thorough examination I concluded that the Nexus's GPU is the culprit. For some reason it just doesn't like multiple graphics being updated at once. Modding the overlay XML allows it to run at full speed.
Can anyone confirm the same reduced framerate issue?. It's also the reason why some ROMs include a setting to remove the navigation buttons glow. I tested with CM9 on the SGS2 and experienced none of the stutters in cases where the GN would. Another example: sliding between sections (comments, ralated, etc.) in YouTube is laggy iff the video is playing.

Agreed, GPU just isn't good enough. I hate the lag with the button glow animations on!
I use an app called root dim, it's really useful. Let's you use a brightness level of 1, which is really quite dim. Free, too.

Thanks for the tip, on the Galaxy Nexus it's possible to set the brightness to 0 by writing to /sys/class/backlight/*/brightness but the brightness is checked and reset to the minimum (default 10) every time the screen is turned on. I guess Root Dim works to the same effect so it runs as a system service. Still, it'd be an awesome addition for people who haven't bothered to mod.

Screen filter may reduce power. But amoled screens save power with lower brightness. There is no difference between lcd vs led on this issue. And modifying the framework to bring min brightness down to 5 rather than 15 saves much more power than screen filter. Its no contest. This isn't different from lcd in this case.

Yes we can write to that sysfs file, but it gets reset. The mod to the frameworks incorporates that backlight file so its now able to go down to 1, 2, 5, or whatever you want. It makes it now stock, so you are no longer capped at 10 (actually I think 15 is the cap I see). But that mod is just removing this cap and making it lower to whatever you want. Stock.
So no extra app is needed. No additional tweak. It now makes the stock brightness able to go down to 1 by itself whenever it needs.
There's much to be said on the internet about screen lag. I realize the most effective combative actions that affect this negative behavior require a combination of settings. Since most of us have wildly various tweaks, settings and requirements for our phones, posing a "how do I get rid of screen lag" question borders on the ridiculous. That said, what has the greatest positive effect on screen lag for your system? Oh, and details on you're settings of course
1. CPU tweaks
2. SysCtl tweaks
3. Build prop tweaks
4. OOM tweaks
5. Minimizing widgets (giving up lol)

In performance what does surface imrprovement do. I have it at disable dithering because i heard it would give more performance when it was default to fix colour banding, But i tried all three and i see no difference. what does it do?
[Q] Force GPU rendering on 2D operations (on some ROMS) & live wallpaper drain change
Greetings, Could not post this in its relevant thread as I'm a new member.
After trying Criskelo ROM v17 I have noticed that the drain of live wallpaper which was nonexistent under the battery in settings, is now visible at a quite high percentage ( not visible to 4-5%).
I'm wondering if this could be due to the "Force GPU rendering on 2D operations" property of the ROM.
If forced gpu rendering could be the cause for the additional drain from live wallpapers, I'll search for a way to make it not forced, I guess

Did check that but its turned off (maybe it's turned on in some other way). What could be so different in a stock based ROM as to change live wallpaper battery drain behaviour so much?

I don't really know but I do have a slightly better battery life when I have Force GPU Rendering on.
Anyone else seem like touchscreen sensitivity on P6 i a bit laggy ? But to understand by what i mean with laggy you must have had a snappy phone before that... It's like for example on the app drawer (i use apex launcher), or anywhere that you have to scroll, you move your finger like 1 cm before the screen actually starts scrolling... Any thaughts on this ? And please do not recommend any app from Google Play, i have tried them all and no improvement. Attached screenshots of my homescreen and app drawer. May i mention that all the settings in my phone are optimised or speed, like drom the developer menu animations and all the rest are set to off, in apex launcher all animations are off, gloves mode on/off, nothing works

There is something wrong with the GPU drivers I believe, our gpu doesn't only suck at 3D but it sucks horribly at 2D also (even SGS2 has better 2D performance). For example a very simple process for the GPU to render: try pulling down the notification bar - it just feels sluggish and not snappy at all on the P6 compared to even the SGS2. Vivante is horrible and Huawei has to do something about it (either release the drive sourcecodes or improve the GPU ALOT.
