Replace <username> with * Every time the username that you want to automatically login HDA is rebooted, when VNC is needed, ssh to the GNOME desktopHDA* The first time without do: vncserver -geometry 1550x1100* After the first time, I type vncs.I have an alias in ~/.bashrc: alias vncs='vncserver -geometry 1550x1100 &> /dev/null &';

If you want to have a script help you to accomplish the task, download [httpNotes://wiki.amahi.org/images/a/a3/AutomaticLogin.rb AutomaticLogin.rb] and run the script as root (directions to accomplish this are below).

Login as root then run * Why that resolution? That fits my monitors with the following commands:<pre>cd /tmpwget http://wiki.amahiVNC window and frame enough to not display scrollbars and move around nicely.org/images/a/a3/AutomaticLogin.rbChange at will!chmod +x AutomaticLogin* It does involve the dreaded CLI.rb./AutomaticLogin.rb</pre>* Since my HDA does not get rebooted often, this is not a huge problem
