With a recent update, the brightness and keyboard backlight functions stopped working from the internal keyboard. With the external keyboard, the display brightness can still be controlled. I tried different kernel versions, but that does not change anything. How can I fix this?
I’m on elementary OS 7.1 (Ubuntu 22.04) with a 13" 12th gen Framework laptop.
If instead, you’re using the /etc/modprobe.d/framework-als-blacklist.conf approach, this may be why it’s not working. We recommending using the above grub method as it is tested.
So, for some reason, grub was configured as quiet splash while I’m pretty sure I added the module_blacklist parameter at some point during the installation.
Not 100% sure if it happens after a kernel update, but I assume that’s the case. I run updates as usual, either through apt upgrade or through the elementary OS’ app store.
