Re: [e-users] Backlight and (lib?)dccutil
a it makes sense.
Based on the original list mail, I didn't understand it relied on the
_library_, and I failed to interpret that.
Thanks for the reply :)

Re: [e-users] Backlight and (lib?)dccutil
On Ubuntu:
wget
https://github.com/rockowitz/ddcutil/archive/refs/tags/v1.2.1.tar.gz
Untar archive, then
./autogen.sh
make
sudo make install
Done.

Hhello!
I've been recently digging into E's ability for backlight, and saw this
post from Mr Raster himself:
https://www.mail-archive.com/git@lists.enlightenment.org/msg23232.html
So, if I understand correctly, E has the ability to change backlight from
regular monitors (and not only for laptops!). And this even has 2 years!
But today I'm posting to the list because this is not working, and I don't
really know why :D
I'm using Ubuntu 20.04 using Niko's PPA (
http://ppa.launchpad.net/niko2040/e19/ubuntu/) and using E 0.25. Also,
Ubuntu has no "libddcutil" but it does have a plain "ddcutil", which I
tried and it's working with my monitor. I've also tried gddccontrol, same
protocol, different lib, also works.
you need libddcutil.so.[2,3,4]. you will have to provide it somehow. it needs
the library. not the binary util. you will probably have to compile and install
it yourself and not rely on packages.
So, I'm kinda curious if my problem is the integration between E and DDC. I
tried looking into the code to reverse engineer (and granted, I am BAD at
it :D ), but the line that I definitely do not understand is this one:
```e_system_send("ddc-val-set", "%s %i %i", bd->dev + 4, 0x10,
(int)(bd->val * 100.0)); // backlight val in e_system_ddc.c```
So, how does that `ddc-val-set` works?
regards!
