Some Notes tips and tricks.

Use X compression over ssh for smoother X sessions

ssh -p 22 192.168.0.x -l user -YC

Optionally use a quickier chipher

For example like blowfish-cbc or arcfour > aes128-cbc > aes128-ctr etc source

In my OPI 2

ssh -p 22 192.168.0.x -l user -YC -c aes128-ctr

Locate devices ip conected to the local network.

Because dynamic IP addresses sometimes I don't know where my thing is...

sudo arp-scan --interface=wlan0 --localnet

Stop graphical session.

Simply kill the dm (display manager). In Armbian Jessie (Orannge Pi 2, with XFCE-4 gui)

Stat/Stop

sudo systemctl start nodm
