Make your own ScreenSaver using GlslViewer

Install

1. Install GlslViewer

sudo add-apt-repository ppa:patriciogv/glslviewer-ppa
sudo apt-get update
sudo apt install glslviewer

2. Install Xprintidle:

sudo apt install xprintidle

3. Clone this repo in your user folder. It will be clone in .glslScreenSaver so you will not see it

cd ~
git clone https://github.com/patriciogonzalezvivo/.glslScreenSaver.git

4. Link the config.yaml to your user folder as .glslScreenSaver.yaml. That's the file glslScreenSaver will use as configuration file.

cd ~
ln -s .glslScreenSaver/config.yaml .glslScreenSaver.yaml

5. Add GlslScreenSaver to run at the begining of your session. Here you have two options:

Run gnome-session-properties, Click on Add and then fill the following data

Name:    GlslScreenSaver
Command: glslScreenSaver daemon

Should look like this

Or run gnome-tweaks, Click on Startup Applications then the + button and search for glslScreenSaver.

Set it up

Edit the ~/.glslScreenSaver.yaml to choose how much time and what shader (o list of shaders) should run

nano ~/.glslScreenSaver.yaml

Make your own screensaver

1. Duplicate any of the default shaders under ~/.glslScreenSaver/
2. Edit it with your favorite code editor and then add it to ~/.glslScreenSaver.yaml
3. Try it out:

glslScreenSaver
