Sweep2Dim uses a modified version of the sweep2wake drivers in combination with LG's LCD KCAL driver to raise or lower RGB multipliers based on sweep gestures.
Right -> Left sweeps drop the kcal multipliers by 73 (or, 33% of the 220 avail)
Left -> Right sweeps raise the kcal mulitpliers by 73
If you sweep left continuously, or until your display goes "black", the driver will trigger a powerkey press and turn off the display.
Since KCAL does not alter your backlight's brightness, you Sweep2Dim can work parallel to auto-brightness, and you can even use it to dim the display lower than the brightness 'slider' allows for.
Sweep2Dim is enabled by default, if you want to disable it, just enable Sweep2Wake/Sleep.​

Dev Resources:
You will need to get a hold of the latest unpackbootimg/mkbootimg/lz4demo/dtbToolCM binaries, here's a copy of my ~/bin
Boot partition is located here: /dev/block/platform/msm_sdcc.1/by-name/boot
To unpack:
Code:
mkdir output
./unpackbootimg -i boot.img -o output
To repack:
Code:
./mkbootimg --kernel output/boot.img-zImage --ramdisk output/boot.img-ramdisk.lz4 --cmdline "console=ttyHSL0,115200,n8 androidboot.hardware=mako lpj=67677 user_debug=31" --base 0x80200000 --pagesize 2048 --ramdisk_offset 0x02000000 --tags_offset 0x00000100 -o boot.img
note: this kernel requires ramdisk_offset 0x02300000
Unpacking/Repacking ramdisk as .lz4
Code:
lz4demo -d /path/to/ramdisk.lz4
mkbootfs /path/to/ramdisk_dir | lz4demo -c stdin ramdisk.lz4
Packing as .gz
Code:
mkbootfs /path/to/ramdisk_dir | gzip > ramdisk.gz

looks very interesting, thanks

second.. Will test.. Works with L port?

If it does, I don't support it. My branch is 4.4.4 but I might make a go at L.

@savoca : Fnally one of the top kernel of N5 to N4...
Great work...
Btw just 1 quick ques...implementation of dt2w, s2w etc have your own modification or standard implementation that most kernel use ?
Reason being 99% implementation have screen freeze issues especially in pocket...so asked...
Screen2dim looks classy

I used showp's implementation if that helps, but you can see all my changes on github. The S2D video was after an early build on M8, so there's visible quirks there like a delayed setting (this has been fixed for this release)

---------- Post added at 08:20 AM ---------- Previous post was at 08:11 AM ----------
Am checking out S2D and just read your detailed explanation of it...am planning to use it in place of S2S and S2W...for that will need to set value to 255 for drop or increase...
My query is is S2D with 255 drop working differently than S2S/S2W...?
Click to expand...
Click to collapse
Well that would be a poor choice, in my opinion. S2D just manipulates RGB mulitpliers, so if you set them all to 0, you still have a backlight shining through a black screen, a major major drain. You could use it inplace of S2S only, however you would need to use DT2W for screen on (I can actually allow S2W aswell, I'll make some changes tomorrow).
To change the amount that is raised/dropped per gesture the sysfs is below.
Code:
echo "1/255" > /sys/module/sweep2wake/parameters/down_kcal
echo "1/255" > /sys/module/sweep2wake/parameters/up_kcal

Yup get the point...Would be great if you could look at it from s2w point...s2s working good...s2w i don't know...almost all have given me screen unresponsive issue...will test furnace 2...if you could allow s2w with s2d i don't know if it will work together with s2s...but if it does hope gives a good solution for non power button use...
Btw are default setting optimal or need to modify any values ? Whats the config you use ?

I'll definitely work in S2W+S2D no problem. The default settings are fine for me as well.

Everything working fine so far. I report battery life and more impressions later.
Edit: maybe you take a look into semaphore dt2w implementation. For me it is better and I don't have the problem of unresponsive touchscreen after boot and not touch the screen in 30 sec.

Very happy to see you here!!
Been using your MotoG kernel from beginning and now for my N4 too

---

Nice something new to flash
Is there are reason for not implenting ROW?
Oh and any preferred kernel app ?

---

@savoca
time to jumping from Semaphore to this !

---

Let's try this out, always love when new kernels come for our device

Preferred kernel app is trickster, I make the sysfs with that app in mind (e.g. intelliplug 3.7 w/ eco_mode_active obj) and their dev team told me they added sweep2dim as a todo for next release.
Here's a boot.img that allows S2D to work with S2W, overriding S2W+S2S only if S2D is enabled, if that makes sense. I also added back all the original TCP/IO (reno,cubic,bic..noop,cfq) and added ROW, didn't catch that Google didn't include it by default. Lastly, I made S2W bidirectional, I guess I'll update this into the next version at the next linux kernel bump.

i would like to make a request please: kindly add pocket mod in your kernel as there is one in elemental x kernel in HTC One M7... (my phone always wake in my pocket and starts tee toun tee taan... Emergency call pee poon paan... etc...

There's some major differences between the drivers on N4 and M7 so I'm not sure how hard that would be, but I do have this commit I can use to make dt2w more less (or more, it's configurable) as well, let me know what you think.

+1 for semaphore dt2w. By far the most consistent/efficient for me.

I feel too configurable cool but you should look at Stratosk's implementation...Semaphore kernel...best and no screen unresponsive issue
Btw tried s2w with 5 min of stay in pocked got unresponsive screen Had to use power button using gravity screen on/off with furnace for now Btw changed governor to intellidemand...uv -75 rest default...working a treat Thanx again
