A great loading screen not only for fans of social engineering, but also for fans of Watch Dogs. The "DedSec" theme for Grub is based on the materials of a computer game and includes many variants depicting key attributes. Bright, acidic colors; frightening slogans, frightened faces of people - all this is present in this set. Fans of minimalism, in turn, may like a simple black screen with a texture and an image of a skull.
The DedSec screen can be cloned from the repository:
git clone --depth 1 https://github.com/vandalsoul/dedsec-grub2-theme.git
cd dedsec-grub2-theme
Regardless of the source, the installation is done with a single command, using Python:
sudo python3 install.py
