Lubuntu Change Autologin User


Where you make the changes to configure a Lubuntu system for automatic login depends on the release you are using. In releases prior to 12.04, the change must be made in the file /etc/lxdm/default.conf. You can open a terminal (lxterminal) and edit it with vi (e.g., gksudo vi /etc/lxdm/default.conf) or use a desktop editor like leafpad (e.g., gksudo leafpad /etc/lxdm/default.conf).
Uncomment the following line and change "dgod" to the intended login name. This ensures that the automatic login recognizes your account and knows where your home directory and files belong, etc.
# autologin=dgod
After the change, the autologin line in your file might look like this:
In Ubuntu releases starting with 12.04, however, you need to edit a different file. With the new display manager, lightdm, a different file is used to manage this setting. So, you edit the /etc/lightdm/lightdm.conf file instead.
lightdm is an X display manager that is fast, extensible and provides the ability to use multiple desktops -- like lubuntu and OpenBox. The lightdm.conf file, after your changes, will look something like this. Note the lack of # signs on the autologin lines:


You can switch back to the using a username and password to log in in by reversing the changes described above. Put the comment markers back in front of the autologin lines and reboot.
In both cases, the username must match the one you set up when you installed the system or you will need to edit your /etc/passwd and /etc/shadow files and move the home directory to match the new name.
Obviously, autologin can only be used for one account. The system needs to know which account to activate when it boots.

Checking if rdairplay is running

I was having a few problems with rdairplay crashing randomly and leaving silence on air. I made a script to check if it is running and restart if neccessary and delete the rdairplaylock file. I hope someone finds this usefull.
 I think someone wrote something similar a while back using a while loop or something.
You could run it periodically using crontab if you wished?
When you save this file dont include the word "rdairplay" as part of the file name or else the running of this script will show up as an "rdairplay" process on your system. I called my script ... but you can choose a name that suits you.


# This returns a value of 0 (if not running) or 1 (if rdairplay running)

statusrdairplay=`ps x | grep -v grep | grep -c rdairplay`

echo $statusrdairplay

 if [ $statusrdairplay = "1" ]; then
 echo "rdairplay is running"

# Remove rdlockfile Change the path to the rdairplaylock file on your set up.
rm /home/geoff2/.rdairplaylock

# Start rdairplay /usr/bin/rdairplay &

#Pause for 10 seconds to give rdairplay time to start up prior the running rmlsend command sleep 10

#Optional you could add this rmlsend line here to play next track if you wished
rmlsend PN\ 1\!
