For me the cpu problem was gone in version: lightdm 1.0.0-0ubuntu2. lightdm 1.0.0-0ubuntu2 was the only version where I did not have cpu usage maxed out.
But now the problem is back in version lightdm 1.0.0-0ubuntu3 (latest version) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/836616 Title: 100% cpu usage in lightdm Status in Light Display Manager: Confirmed Status in “lightdm” package in Ubuntu: Confirmed Bug description: Hey, it seems that there's an issue with 0.9.4 cpu usage.
