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.

EXAMPLE: http://ubuntuforums.org/showthread.php?t=1559941

I'm pulling my hair out, and I don't have much left!

    I'll just answer in a comment for now because this question is currently closed. 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. Apr 27, 2012 at 1:46

    The sleepd method was a huge win in our dormitory as we moved from single user to ldap. (The machines just hanged on lightdm for hours)

Install sleepd.

sudo apt-get install sleepd

By default, the system will go to sleep after 10 minutes of inactivity. Settings can be changed in /etc/defaults/sleepd. Set the PARAMS variable with -u [number of seconds] to set the number of seconds of inactivity that will cause the system to sleep. Check out the manpage for more options.
