I have installed Remmina on a Lenovo thinkpad E325 with 11.10 and it works fine. Then I did exactly the same on my Samsung RV511 (2GB RAM). The installation obviously went fine. But when I click on the Remmina icon in order to start it - nothing happens.
Here's what I get. Ubuntu 11.10 64bit. Gnome 3.
$ remmina
