Bug Description
After updating to Ubuntu 16.04 from 14.04, on my Lenovo T420s, the screen is very dim after resuming from standby. Changing the brightness by settings or fn keys restores the correct state.
This is very annoying because it is a repeating regression that happens again and again over the last years. Almost every distribution upgrade breaks the brightness after standby and took some month or even years to have it working correct again.
