Hi. I have a use case where i want to ensure that all NUCs in my fleet bump the brightness of the connected USB-c touchscreens to 100% on container start using ddcutil, but it seems like the BalenaOS NUC distribution does not contain the i2c-dev kernel module required to use the tool.

`xrandr --brightness` etc is not feasible since it does not alter the hardware brightness, only the gamma of the video output

Is there a workaround for this or any plans to include this kernel module in future updates to the NUC dist?

Hi

It does seem that the intel-nuc image is not built with the `i2c-dev` kernel module. I’m confirming with the os team for alternatives or if we can enable this.

thanks
