Note: All tests are being done on 2013 macbook air
Ubuntu on MacBook almost works perfectly like any other laptops out there. There are some issues though. One the most annoying one is the brightness issue. Once the lid is closed, it goes to sleep state. After waking up, only 2 options for the brightness 0 or 100.
To solve the issue we need to install mba6x_bl
Follow the following steps
╰─○ git clone git://github.com/patjak/mba6x_bl ╰─○ cd mba6x_bl ╰─○ make ╰─○ checkinstall ╰─○ sudo dpkg -i mba6x-bl_xxxxxx_amd64.deb (check your folder for the exact name of deb file generated from check install) ╰─○ sudo depmod -a ╰─○ sudo modprobe mba6x_bl ╰─○ sudo reboot
That’s it folks. You have successfully squashed the bug
Enjoy smile
