Ubuntu Dreams of Electric Sheep...

About 4 years ago Ubuntu, a very popular Linux desktop distribution, decided to strike the beautiful Electric Sheep screen saver program from it's repositories (think app store), apparently because of some licensing issue or other. This decision followed a philosophy of "fat trimming", striking screen savers and other unnecessary bloat from the default set of installed programs, as we no longer need them to save our CRT monitors from suffering ghost image burns.

Although we no longer need screensavers to keep images from burning a permanent image onto our CRT screens, some users, like myself, still consider them a way to convert our unused monitors from a blank wall of darkness into a nice display of artwork, bringing a splash of life to our offices or our living rooms. The inspired Electric Sheep program in particular was an exceedingly elegant and beautiful choice for this task, and there was no simple path to bringing it back, as there is for any Android device (Via Google Play), Windows computer, MacOS, Ipad/Iphone (Via App Store), and even Apple TV (just do a search in the Apple TV app store). Now, thanks to the ever vibrant open source community, there is finally a simple solution to bring life back to our sleeping Ubuntu screens, and with it a bit of color back to our offices and living rooms.

Inspired by the Philip K. Dick novel, "Do Androids Dream of Electric Sheep?", this small program will use your sleeping CPU cycles to render small bits of the collective "dream" of every computer running this program. Best to let the artist, Scott Draves, explain his work in his own words... 

 

Pretty nifty, right? Ready to go? These simple steps walk through the pretty painless process of installing Electric Sheep on Ubuntu 14.04 or later... Ready... Set...

 

Installing Electric Sheep on Ubuntu 14.04 and beyond.... 

Step One: Preparing Your System

 

First we need to remove the default Gnome screen saver program, which merely handles blanking the screen, so open up the terminal and enter in:

sudo apt-get remove gnome-screensaver

 

Now replace Gnome screen saver with the functional X-ScreenSaver:

sudo apt-get install xscreensaver

 

... and add an optional small fix for you lock screen (if you use this function)

 

sudo ln -s /usr/bin/xscreensaver-command /usr/bin/gnome-screensaver-command

 

... and optionally install a whole slew of fancy "X" style screen savers :)

sudo apt-get install xscreensaver-gl-extra xscreensaver-data-extra

 

Now we have to install two custom sources (PPA's) into our app store (the Ubuntu app repository) 

sudo add-apt-repository ppa:caffeine-developers/ppa

sudo add-apt-repository ppa:ichthyo/zeug

 

..and now update the repository list with our new PPA sources

sudo apt-get update

 

That's it, the system is now ready for Electric Sheep :)

 

Step Two: Installation and Configuration

 

We have to install both Electric Sheep, and the handy Caffeine program, which inhibits screen saver activity for doing things like watching movies. Simply enter the following into your terminal:

sudo apt-get install electricsheep caffeine python-glade2

 

Want to see it in action real quick? Just type electricsheep into your terminal wink It might take a minute to download some sheep.

Now we just need to make a quick edit, and add the following line to the config file at "/home/YOUR_USER_NAME/.xscreensaver" :

- GL:                 electricsheep --root 1                \n\

 

Next we want to just fire up Xscreensaver and Electric Sheep and get the references set. First do a quick search for "Screensaver" in the menu and set it up according to your needs. I use single screen saver mode, and select Electric Sheep, a real no brainer, really. Then put the following line in your terminal and set Electric Sheep to your needs.

electricsheep-preferences

 

You might notice that you can enter in a user name there. You can go and sign up for an account, I hear that there's special "Gold Sheep" on the way ;)

Finally we want to add a functional start-up option for Caffeine, go to Startup Applications and if these are not there, add in one for caffeine

/usr/bin/caffeine

.

..and one for the little indicator icon that makes it a breeze to turn on and off at movie time

/usr/bin/caffeine-indicator

 

That's it! You're ready to start wondering if you've added sentience to your computer! Happy Dreaming!


 

How about a good read while you enjoy your new screen saver?

 


 

If you want to revert your system, simply put these 3 commands in your terminal.

sudo apt-get remove xscreensaver xscreensaver-gl-extra xscreensaver-data-extra electricsheep caffeine python-glade

sudo rm /usr/bin/gnome-screensaver-command

sudo apt-get install gnome-screensaver

 

And remove the Caffeine startup entries.
