WARNING!!! Kubuntu 12.10 install doesn't provide Login Screen controls by default

[pwabrahams]

I installed Kubuntu 12.10 and wanted to use the "Convenience" login feature. But the necessary module in System Settings (Login Screen) was missing. The LightDM controls don't provide it.

The way to get it, I've learned, is to install the kdm package, which isn't included in the initial installation. An easy fix, but devilishly difficult to discover. I do wish that kdm was included in the initial install.

Did you try to get auto-login working with lightdm? I think the main problem right now is they gave us a blank config file rather than one with some info.

Create a file /etc/lightdm/lightdm.conf and add the following content:

[SeatDefaults]
autologin-user=<YOUR USER>
autologin-user-timeout=0

[pwabrahams]

Yes, i did try using the lightdm settings in System Settings, and it didn't help. But installing kdm was an even easier solution than creating a config file. My complaint was that there was a loss of visible function between the 12.10 release and the 12.04.1 release, though a loss that was easily remedied.
