since you can't add repository from ppa:alexanderk23/ppa
you can download amd64.deb from here:
https://launchpad.net/~alexanderk23/+ar ... /+packages
then install xscreensavers ( i tested with xscreensavers but if you know how to works without it comment here)
sudo apt-get install xscreensaver xscreensaver-gl-extra xscreensaver-data-extra
launch xscreensaver from your start menu > settings >screensaver (this is needed to create .xscreensaver file)
exit xscreensaver
add this entry to .xscreensaver file located at /home/your username (maybe you need to put show hidden files)
gluqlo -root \n\
save the file
to launch the gluqlo you can set up command launcher on your system tray with this command
/usr/lib/xscreensaver/gluqlo -root
to exit gluqlo press esc key
