How-To: Install Ubuntu and Linux Apps on Your PlayStation 3
Step 6: Install a Few Living Room-Friendly Apps
So you've got that fresh copy of Ubuntu just sitting there, begging for some action. Not sure where to start program-wise? Feeling a little lost on how to maximize your distro inside the entertainment room atmosphere? We've got you covered. Here are some great apps to help you on your way.
AmaroK
Amarok is a Linux customized and tweaked fully-featured digital music player. A great choice for turning your house into a certifiable digital music funk-factory (complete with an embedded visual album cover plugin). The perfect addition to any 7.1 surround THX system just itching to rock out. Here's how to install and use it.
First, make sure you're connected to the Internet, and open up a terminal. From here, type out the following line and press enter:
sudo apt-get install amarok

Let the process complete and then go to 'Applications' → 'Sound and Video' → 'Amarok' to start the player. The initial setup screen should launch. Go ahead and click 'Next.' Since you probably don't have any music folders allocated yet, simply select the top box to include all of the options, and click 'Next' again.

When given the option for a database setup, make sure the drop-down menu is set to 'SQ-Lite,' and then continue to 'Finish.' Amarok will now be ready.

To open up a music file, go to 'Playlist' → 'Add Media.' From here, just navigate to your music directory (or wherever your audio files are located) and press 'OK.' Your selection will now be added to the playlist. Do note that Amarok might be sluggish for the first 5 minutes when loading. After that though, it should work fine.
Binge on SNES9X Super Nintendo Emulation and Set Up Your Sixaxis/Dualshock Controller
Admit it. You used to play console games all the time. Especially the SNES. Sure, you can assert that the PS3 you're currently using was a dedicated Blu-ray player before Ubuntu, but we know better. Bottom line: there's no point in avoiding your console gaming roots (misguided as they are), so why not embrace your nostalgic heritage instead? Fire up this emulation app with a few tips on running your wireless controller in conjunction, and jump back into the classic 16 bit days of ye olde Mario Kart.
First things first: a retro emulator is of little use with a mouse and keyboard. WASD is fantastic for Quake. It sucks for side-scrollers. Let's get that PS3 controller back in action.
Download this file to the desktop. Double-click the folder when finished and select 'Extract Files.' You should now see two package icons. Double-click the icon that reads: 'bluez-sixaxis-bin_powerpc.deb' and let it install.

Once it's finished, close the dialogue screen and double-click the next icon, which should be titled: 'bluez-sixaxis_rc1.1_all.deb.' Allow this file to finish setting up as well, and then like the other, close the screen at the end. You don't need your Sixaxis or Dualshock yet, so leave them powered off for now.
Make your way to 'Applications' → 'Accessories' → 'Sixaxis-GUI.' From the small pop-up screen, select 'Setup Menu,' and then click 'Setup First Connection.' (You'll want your fully charged controller ready to be turned on at this point).

Press the PS button when prompted, and then hit 'OK.'

After this, close out of the welcome screen and go back to 'Applications' → 'Accessories' → 'Sixaxis-GUI,' and select 'Task Menu.' Click 'Enable Keyboard and Mouse,' and then click 'Fake Joystick,' and hit 'OK.'

All you have to do at this point is select 'Turn Off Sixaxis,' wait about 10 seconds until you're returned to the main menu, and then click 'Connect Sixaxis to PC.' Now your controller is ready to party like it's 1992.
Now let's snag that emulator. Open up a terminal window, being sure to press enter after entering the following text:
sudo apt-get install snes9express snes9x-x
