Use Remmina (remote desktop client) from Linux to log-in Raspberry Pi xrdp server

In previous posts, it show how to "install xrdp (X Remote Desktop Protocol) on Raspberry Pi and log-in from Windows using Remote Desktop Connection" and "log-in from Android using Microsoft Remote Desktop app". We can also log-in from Linux with Remmina (remote desktop client).

If you are running Ubuntu, may be you already have Remmina installed. If not, install with the command:

$ sudo apt-get install remmina

and run it with 

$ remmina
