The daily driver.

A mid-2012 MacBook Pro that runs linux with Ubuntu and Regolith alongside a selected range of software for light or text-based projects, communication and traveling.

It was out of use for a few years because of a broken graphics chip that was bridged in late 2022. The nVidia graphics chip is now not usable anymore which means that it cannot run graphics intense software and the HDMI and Thunderbold outputs are useless.

There are a few things to get everything working right with ubuntu.

Regolith is a desktop environment that can be either installed on top of Ubuntu or with a custom installer image.


Backlight Brightness

xrandr --output eDP-1 --brightness value

The value is between 0 and 1.

Wrote a bash script and mapped it to brightness keys XF86MonBrightnessUp/Down in i3 config file.

Startup Chime

To decrease the volume of the startup sound, edit the EFI variable SystemAudioVolume-7c436110-ab2a-4bbb-a880-fe41995c9f82.
Drop to root access using sudo -su, then change directory cd /sys/firmware/efi/efivars/.
To overwrite the variable content, first change the immutable bit of the file with chattr -i SystemAudioVolume-7c436110-ab2a-4bbb-a880-fe41995c9f82.
Now change the content with printf "\x07\x00\x00\x00\x00" > SystemAudioVolume-7c436110-ab2a-4bbb-a880-fe41995c9f82.

Change the immutable bit again with chattr +i SystemAudioVolume-7c436110-ab2a-4bbb-a880-fe41995c9f82.

Alt/Cmd keys switched

Use Gnome Tweaks to switch the keys.
