That was quick, thanks!

@whynothugo, done

Can you add aarch64 to the arch array? Builds fine here.

I am missing something. I have the package installed along with linux-headers and dkms. I added i2c-dev and ddcci_backlight to etc/modules-load.d/ddcci.conf, but still the monitors don't show up in backlightctl. I am able to control the brightness through xrandr though, although I could do that before installing this package.

Edit: I was able to get ddcutil control working by following the suggestion here (for nvidia cards): https://forums.developer.nvidia.com/t/gddccontrol-issues-with-nvidia-drivers-i2c-monitor-display-ddc-dp-hdmi-failing/30427/61

I added 

options nvidia NVreg_RegistryDwords=RMUseSwI2c=0x01;RMI2cSpeed=100

to /etc/modprobe.d/nvidia-backlight.conf and rebooted.

Simply creating a /etc/modules-load.d/ddcci.conf that contains

i2c-dev and ddcci_backlight

did the trick for me after I've been struggling for eternity while trying to get it working with systemd units and building modules into the initramfs.

Doesn't work if ddcci is loaded instead of ddcci_backlight - don't ask me why.

Be sure to add the i2c-dev and ddcci modules to mkinitcpio.conf

This is a great package, but can it specify the required dependencies please: dkms and linux-headers?

tukusejssirs commented on 2022-01-15 18:57 (UTC)

I tried to install this package, but the following error was shown:

 -> Could not find all required packages:
    ddci-driver-linux (Target)

Is there a missing dependency or am I missing a package?

FYI: this will not compile with recent kernels due to kernel commit fc7a6209d5710618eb4f72a77cd81b8d694ecf89 (a trivial callback signature change). A merge request request is currently pending upstream which will bump the version too, but the fix is easy to apply in the meantime if needed: https://gitlab.com/ddcci-driver-linux/ddcci-driver-linux/-/merge_requests/8?commit_id=bf9d79852cbd0aa5c2e288ce51b8280f74a1f5d2

Just an FYI: I had to add myself to the i2c group and copy over the ddcci udev rules to get this working on startup
