=====ubuntu de-ubuntuization=====

Ok, now we have our shining new oneiric install on our ac100.\\
We just realized on our desktop machine that unity sucks; but on our ac100 it's ever worst. All the 512MB of ram filled by the ubuntu-experience-stuff.

Waiting for a Debian Installer for Humans (something like the excellent oneiric installer) or waiting for ArchLinuxArm... or Angstrom distribution... or anything else - we have to grow up and skill up, we are new ac100 owners, we are noob - this is

==troubleshooting==
i had problems connecting with NetworkManager to protected wifi networks;
add your user to the 'networkmanager' group:

  sudo gpasswd -a `whoami` networkmanager

==reboot==
cross your fingers and reboot :)

==suspend on lid-close==

to suspend from commandline: 

  sudo pm-suspend # pre-cooked script that does the clean thing (have a look to it: cat /usr/sbin/pm-suspend)

or 

  sudo bash -c "echo mem > /sys/power/state" #quick and dirty solution :)

i'm trying to make scripts/programs to manage with lid close event..
but i lost the reopen-after-suspend and first close-after-resume events..
currently suspend-on-lid-close is working only every 2 close so... work in progress!
