trying out this debian-based distro as ubuntu is getting a bit boring
I expect to learn more using a “proper” debian I thing – openbox is a bit tricky as a window manager (opposed to a desktop manager / environment)
note: apt-get dist-upgrade apparently replaced upgrade

some thoughts on laptop / sensors:
lm-sensors
sensors-detect

use these repositories for xv (gxine wants it)

now let’s save some power
create /etc/pm/power.d/powersave

dont forget to make it executable!

install keyring, GPG keys, SSH keys
.ssh/ needs to be 700, the actual key 600
don’t forget to add it to the system using ‘ssh-add’ – see below for more tips
easier: install ‘keychain’ and tie it to the terminal to unlock ssh key
update your $HOME/.bash_profile file
$ vi $HOME/.bash_profile
Append the following code:
### START-Keychain ###
# Let re-use ssh-agent and/or gpg-agent between logins
/usr/bin/keychain $HOME/.ssh/id_rsa
source $HOME/.keychain/$HOSTNAME-sh
### End-Keychain ###
this will work for shell – add it for “terminator” aswell, the default for !#
next, install mosh,
Apt-get install mosh
open a port on the remote server between 60000 and 61000 and apply it to the raspi as server
take over a screen session using mosh:
$ mosh remotebox — screen -dr
