Brightness keys (if not implemented in hardware directly) need to be
known and mapped by the kernel.
Please:
1. Tell us the exact laptop model.
2. Run: sudo apt install evtest
3. Run: sudo evtest
4. Select your keyboard and then tap the Fn+brightness keys.
5. Copy and paste what you see in the evtest output.

Title:
Brightness can't be changed from keyboard
Status in linux package in Ubuntu:

Bug description:
Brightness level can't be changed from keyboard with the Fn key and
the corresponding designated key. Other functions like changing
volumes involving the Fn key work perfectly. The only way I can change
brightness is from the status bar.
