boot@terver:~/.unison# unison -ui text crossing_groups_sync.prf

tweaks when setting up new 11.10 system

install mdadm then run sudo mdadm –assemble –scan to recreate the raid

if skype won’t run from the launcher try command ‘skype’ at cli

install guvcview to adjust webcam pictures, save load them into skype

nb. synaptic is not part of 11.10

no screen saver by default in 11.10:
sudo apt-get install xscreensaver xscreensaver-gl-extra xscreensaver-data-extra
