I am a little confuse, there is a thumb version of mce?
I thought to create a thumb version of a package, freemangordon need to recompile the package using Thumb2 instruction set.
How come he can create mce thumb version when he previously don't have the source code of mce?
</OOT>

Anyway, I installed this mce on my phone and found no error so far.

That's the big thing about - now, we *have* source code, thanks to jonwil, who reverse-engineered it.

After re-read that post, I realized that I misread handaxe post.
Sorry, please ignore my previous post.

Hi guys can someone tell me where i can find the original mce file? I want to go back because of a bug that makes it pretty unusable for me:
whenever the keyboard stays open and the display turns off because of the timer, the keyboard gets locked and can only be unlocked when touching the display.
When i am playing music in the car i let the keyboard open and can skip songs with the left + right keys or stop it via space. In the car i don't look at the phone where to click, now with the mce replacement i have to touch the display and look if i am still in the playing-window...
I also don't want to keep the display the whole time turned on. 10s timer is way enough..
Please fix it or upload someone the original mce.deb .

With my day to day normal usage, there isn't any difference really... Haven't noticed any bug or anything else.
BTW I have thumb version of CSSU, it seems like there's a problem with it (or not) as I'm not sure

Can't you download the original mce file from repo?
# apt-get install --reinstall -d mce

---edit---
It turn out that I still have it in my /var/cache/apt/archives.
Please find the original mce in the attachment

Actually, I'm not sure if I've installed it since the version is the same.. I did grep -i mce and it shows 1.8.126+0m5, same as the original mce provided above. There were errors when installing though..

CSSU-thumb user here.

Now that we have source for MCE, does this change in any way:

(Though the LP5523 chip has 3 engines meant to control R, G, and B, the mce program exlusively uses engine3 for kbd backlight and so doesn't support pattern definitions for engine3. mce is closed source and thus this can't be fixed in any reasonable way. If mce were open, an alternative compatible format was possible:

from:
http://wiki.maemo.org/LED_patterns

I admit to not really understanding exactly what is mean by "engines" and how the n900 hardware uses the keyboard LEDs with the LED hardware. Looking at the MCE source though, it appears the keyboard LED pattern is hardcoded... and there are 6 LEDs? Some hacking on MCE could give us control over those LEDs individually?

we already have control over the 6 kbd LEDs.
See

sudo gainroot;
sleep 5; stop mce; echo "disabled" >/sys/class/i2c-adapter/i2c-2/2-0032/engine3_mode; j=10; while [ ${j} -gt 0 ]; do j=$(( j-1 )); for i in $(seq 1 6); do echo "100" >/sys/class/leds/lp5523:kb${i}/brightness; sleep 2; echo "0" >/sys/class/leds/lp5523:kb${i}/brightness; done; done; start mce

(except of sudo gainroot, it's ONE line! Slide open kbd and then lock the screen immediately - during the initial "sleep 5" - after firing the line in xterm)

To understand what's this stuff about engines, try this instead:

sudo gainroot;
sleep 5; stop mce; j=10; while [ ${j} -gt 0 ]; do j=$(( j-1 )); for i in $(seq 1 6); do echo "100" >/sys/class/leds/lp5523:kb${i}/brightness; sleep 2; echo "0" >/sys/class/leds/lp5523:kb${i}/brightness; done; done; start mce

It's just missing the disabling of engine3 which we can't control as long as mce is running, so the kbd-dimming program you correctly spotted in mce is running all the time and dimming the LED in a fraction of one second after this shellscript turned it on. Even worse: mce is loading this program and starting it all the time (actually with every event like keypress etc)
That's what I called "abuse of a smart engine for stupid dimming" and suggested to rather let mce do it once in software than program engine3 to do it. Thus we could use all 3 engines for true rainbow color effects in indicator LED.

Summing it up and parsing into human-readable sentence - yes, it is possible since we have MCE source, but require some solid works of writing by clever coders, to make it usable for mass-consumption, without breaking any functionality.

Cheers,
