Should linux-headers not be part of makedeps?

Here it is: https://aur.archlinux.org/packages/ddcci-driver-linux-dkms-git . Currently works even with 6.9

I have decided to wait for upstream to tag their new version rather than patch 3eb20df68a545d07b8501f13fa9d20e9c6f577ed (upstream probably hasn't done so in light of https://gitlab.com/ddcci-driver-linux/ddcci-driver-linux/-/merge_requests/15#note_1830989470 's citation that the commit causes a new regression even for kernel version 6.7).

To satisfy people's needs, someone can create and maintain the -git package variant. If nobody does so within a few days, I can.

As mentioned here, running the following makes ddcci/ddcci_backlight pick up the device in 6.8 with the most recent upstream commit:

echo 'ddcci 0x37' | sudo tee /sys/bus/i2c/devices/i2c-7/new_device

Now my backlight control works \(^o^)/

A different (or multiple) i2c device may be needed on your system, just check the destination of the symlinks in /sys/bus/i2c/devices. The one(s) you want will go to a DRM card-connector sysfs. 0x37 is the address where the ddc/ci protocol is used so it should not be changed.

Forgot to say I'm also on Intel iGPU. Mesa, mkinitcpio, linux 6.8.9, 15.patch, dkms and linux-headers, everything is installed and set up correctly but GNOME does not show the slider like before Linux 6.8.

MrHighVoltage commented on 2024-05-06 08:07 (UTC)

It also doesn't work for me either on 6.8, no messages in dmesg. Interestingly, KDE Plasma can still change the brightness over ddc/ci, even without the module loaded (but only on AMDGPU, it doesn't seem to work with an Intel iGPU, but ddcutil is still working).

@dreieck were you able to see the slider in Gnome or another window manager?

LarryDave commented on 2024-05-05 15:35 (UTC)

I patched and built it for Linux 6.8 and installed it. I have the module in mkinitcpio.conf to load at early boot but GNOME still won't show the slider. Any help?

Patch for Linux 6.8 has now been incorporated into git master branch of upstream: https://gitlab.com/ddcci-driver-linux/ddcci-driver-linux/-/merge_requests/15

No new release yet, so I recommend that in the meantime you add the following patch manually to the PKGBUILD:
