Slim raspbian default Raspberry-pi Image

Wed, 26 Dec 2012 by Frank Lazzarini

The 'default' Raspberry-Pi image Raspbian comes with a lot of overhead which is mostly not wanted at least in my case. Here is a little aptitude line which gets rid of all the stuff we don't want on our little embedded system like Xorg server, fonts, X Applications, LXDE and so forth.

sudo apt-get remove --purge x11-common x11-utils x11-xkb-utils x11-xserver-utils \
  xarchiver xauth xkb-data xinit lightdm lightdm-gtk-greeter consolekit \
  libx{composite,cb,cursor,damage,dmcp,ext,font,ft,i,inerama,kbfile,klavier,mu,pm,randr,render,res,t,xf86}* \
  lxde* lx{input,menu-data,panel,polkit,randr,session,session-edit,shortcut,task,terminal} \
  obconf openbox gtk* libgtk* python-pygame python-tk python3-tk scratch tsconf omxplayer squeak-vm \
