if I run

Perhaps you could describe what you mean by "full system update". What is the output of emerge --info? What package(s) did you change as part of the update?

Your full system update probably replaced xf86-video-intel with modesetting and it doesn't support xbacklight.

thanks @tholin. Indeed xf86-video-intel was not installed.. So I emerged it, rebooted and now xbacklight works.

Is there a log where I can double check if xf86-video-intel was removed by the depclean?

thanks

[astor86]

yes indeed xf86-video-intel was removed by a depclean after the system update. I checked
