How can I set my mouse cursor to be black on Ubuntu 14.04?
Open terminal and type:
cp -r /usr/share/icons/DMZ-White ~/Documents/
This is to make a backup of the current theme. (just in case you want to reverse the changes)
Next copy the icon folder to replace the icons with this command:
sudo cp -r /usr/share/icons/DMZ-Black/* /usr/share/icons/DMZ-White/
Logout and login, there you have it, a nice black mouse cursor.
To recover the white mouse cursor, from your backup, do the following command then logout and in again:
sudo cp -r ~/Documents/DMZ-White/* /usr/share/icons/DMZ-White/
