vimanuelt: Thanks for your response! But when I attempted this, I got the following message:
sudo pkg install git
Password:

Updating GhostBSD-base repository catalogue...
GhostBSD-base repository is up to date.
All repositories are up to date.
git clone vimanuelt/brightness-control
fatal: repository 'vimanuelt/brightness-control' does not exist
What am I doing wrong? Thanks in advance
