http://crunchbang.org – yesterday i followed these instructions - http://linuxg.net/how-to-install-mate-on-debian-wheezy/ - and got Crunchbang completely broken (even internet access i got missing), after a massive package removing from apt-get update and apt-get upgrade, so i had to reinstall it again - (and weird is that on the other computer that i have Crunchbang-wheezy installed i have Mate installed there perfectly and co-existing with Gnome3 ) - do someone has a great tutorial about how must we do on Crunchbang?
