    Question Macbook Pro monitor does not dim

    I've just installed 20.04 on my MacBook Pro. Currently the display will not dim at all. I have found only one way to fix this and that is by using what I learned in this post

    https://bbs.archlinux.org/viewtopic.php?id=232317

    If I use the solution of typing the following into the terminal I can dim the display

    Code:
    sudo setpci -v -H1 -s 00:01.00 BRIDGE_CONTROL=0
    Once I reboot the system this fix no longer works. Do I need to add this to some start up script? I'm quite new to Ubuntu and just starting to figure things out. Thank you!
