GLMatrix screensaver configuration in Ubuntu Gutsy 2007-10-27

I have no idea why but Ubuntu doesn’t allow to configure the screensavers it comes with. Not those screensavers were not configurable, but in contrast to xscreensaver-demo, Ubuntu itself does not offer access to their visual config 🙁

What I wanted to do is stop GLMatrix from rotating the matrix, which would have been -no-rotate on the command line. Editing glmatrix.desktop in /usr/share/applications/screensavers finally helped:

The modified file looks like this:

[Desktop Entry]
Name=GLMatrix (without rotation)
Comment=Draws 3D dropping characters similar to what is seen in the title sequence of “The Matrix”. [..] Written by Jamie Zawinski.
Exec=glmatrix -root -no-rotate

This was a great tutorial. Btw I figured out when I was trying modify glmatrix on my system that the color is determined by a alpha level. If you want to change that the image doesn’t help you. You can add a few lines of code though and take care of it.
