@joshtau Just downloaded
ddcci-driver-linux-v0.4.3.tar.gz
and after runningtar -tf ddcci-driver-linux-v0.4.3.tar.gz
, it still returnsI do notice that v0.4.3 doesn't have a corresponding GitLab release. But when the next version comes out, I'll be sure to use sha256sum instead of b2 and the ${srcdir} in the package function

I think this needs to be updated, as the file might have changed recently, the directory now has a git commit instead of a version number. Can either use * or the git version.
RE running this --
Prechecks: 1. Ensure you've rebooted after loading it, just incase.. 2.
dkms status
shows it's installed (ddcci/0.4.3, 6.2.8-arch1-1, x86_64: installed
)It can be a bit finnicky, here is what I had to do to make it work:
sudo modprobe ddcci dcci_backlight
/sys/bus/i2c/devices
(thanks to this tip).You can find this with ddcutil, ensure you have
i2c-dev
modprobed.ddcutil detect
orddcutil detect --verbose
:So it's
/dev/i2c-6
You then have to add this a new device, replacing XXXX with 6 (or whatever your ID is):
The driver is great, my timing was anywhere between 500ms to 700ms with the userspace tool
ddcutil setvcp 10 55
, compared to ~60ms for brillo (brillo -el -S 70
), or 80ms when using brightnessctl (brightnessctl set 50% -d ddcci6

Does anyone know why ddcci doesn't load properaly? Output to
dmesg
[ 4.152434] ddcci: loading out-of-tree module taints kernel. [ 4.152465] ddcci: module verification failed: signature and/or required key missing - tainting kernel

PKGBUILD
for version 0.4.3 (patch file no longer necessary since it's included in 0.4.3 update)Porous3247 commented on 2023-01-26 22:36 (UTC) (edited on 2023-01-26 22:39 (UTC) by Porous3247)
@ewout I still get the same error/error log (linux-zen version is 6.1.8)
EDIT: nevermind, I just had to forcefully remove $XDG_CONFIG_HOME/paru/clone/ddcci-driver-linux-dkms

@ewout One quote from Christoph Grenz (the developer): "It seems like the kernel developers want to deprecate the backlight devices in sysfs in the long term and instead provide another API where it is easier to match which backlight controls which display."
So, maybe the author just waits for the certainty.

Upstream seems unmaintained, may needs to be forked in the future.

@tukusejssirs @Porous3247 Should build again on kernel 6.1+
tukusejssirs commented on 2023-01-26 08:21 (UTC) (edited on 2023-01-26 08:25 (UTC) by tukusejssirs)
Is there anyone who is able and want to maintain this package? Thanks!
Thanks, @ewout, for such prompt reaction! ;)
