I can't figure out how to get Ubuntu 11.10 to suspend when idle from a lightdm login screen. I've found methods to do this from gdm, but even those reference configuration files that aren't present in 11.10.

I'm pulling my hair out, and I don't have much left!
sudo apt-get install sleepd
The default is 10 minutes of inactivity. You can change the defaults by editing /etc/defaults/sleepd. Set the PARAMS with-u [number of seconds]
. Check out the manpage for more options. – Richard Ayotte Apr 27 '12 at 01:46
