Shell script to enable Remote desktop on ubuntu

activating from preferences doesn't always work, i ended up installing tightvncserver. eventually i'm frustrated with ubuntu (i needed to use bluetooth) and goes back to openbsd.

but maybe the article is intended for enabling remote desktop on remote ubuntu (like sftp the code, ssh to remote ubuntu, execute vnc viewer) ... but that requires ssh server (ubuntu doesn't have by default, only ssh client -- more secure but less usable)
