Ubuntu - Auto-login and lock screen

I like to set up my Ubuntu workstation to automatically log into my account and then immediately lock the screen. This allows all my processes to start up and also allows me to VNC into the main console session via the Remote Desktop (vino) server. There are a few ways to set this up:


First, set up auto-login:

System > Administration > Login Window > Security tab

Check ‘Enable Automatic Login’ and choose your username. Click ‘Close’.

As for locking the screen after login, you can try adding the following command to System > Preferences > Sessions:

gnome-screensaver-command --lock

or

xdg-screensaver lock

I found that these commands worked for me when logging in and out of the box. However, I found that they did not work for me when I rebooted my workstation. If any of the other commands listed Sessions utilize gnome-keyring, such as ‘mail-notification’, the gnome-keyring password prompt seems to keep the screen from being locked. To work around this, I created a script called ‘lockstartup’. This script does the following:

1. Pauses for 10 seconds (a step I found necessary in order to get the script to work correctly)

2. Locks the screen

3. Pauses for another 10 seconds (again, a step I found necessary)

4. Starts any applications that use gnome-keyring

Here is what my script looks like:

#!/bin/sh

sleep 10

xdg-screensaver lock

sleep 10

mail-notification

After you save the script, make it executable:

$ chmod +x lockstartup

And then add it to System > Preferences > Sessions. If you reboot, you should be automatically logged in and then see the screen lock. Once you unlock the screen you should be presented with the gnome-keyring password prompt.

I am using this on Ubuntu 8.10 Intrepid Ibex. I have not tested this on any other releases.
