I’ve been getting an Ubuntu server running recently (FINALLY), and in order to make it run headless (without keyboard, mouse, or monitor), there’s a few things one needs to do:
1) Enable Auto-Logins (optional)
All depends upon how you set things up, but you may want to run everything easily through a default user account — just go to “System > Administration > Login Screen”, and set it up.Â (These instructions are for the GUI of Ubuntu, of course — I’m not a CLI-queen, and would rather edit things quickly through an interface that I’m familiar with than search forums for hours trying to find the esoteric commands necessary to do this stuff manually, sorry.)
2) Enabling Networking With Automatic User Login
Now, you may have set up automatic logins, but noticed that you always have to enter in your account password manually anyway once your network tries to connect — took me a while to figure out this one, but just go to “System > Preferences > Network Connections”, and in the type of connection you’ll be using, make sure the option for “Available to all users” is selected at the bottom.Â That’s it.Â I feel dumb for not figuring this out long ago.
3) Enabling VNC to Run Headless
As per the instructions I found here, you have to
- Edit “/etc/gdm/Init/Default” to include the line “/usr/lib/vino/vino-server &” right before “exit 0”
- Edit “/etc/gdm/custom.conf” (or “/etc/gdm/gdm.conf” if older than Ubuntu 10.04) and add “KillInitClients=false” — this will prevent any existing VNC clients from being killed if you do login on the server physically
- Do a “sudo vino-preferences” and enable the necessary stuff
More to come, including the Minecraft configuration scripts!
