I had the same problem since the lightdm update but my symptom was more disrupting : my Unity session was switched to english instead of my default setting (french).
Using patch in comment #3 works for me. I think this bug should get a high priority. -- 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/1162836 Title: $PATH does not contain /usr/games - /etc/environment not sourced or environment not preserved Status in “lightdm” package in Ubuntu: Incomplete Bug description: This is similar to #798277, however is a new problem. Please continue reading. Problem appears in lightdm 1.2.3-0ubuntu2. Downgrading to 1.2.3-0ubuntu1 resolves the problem. Upgrading to 1.2.3-0ubuntu2 again causes the problem to reappear. Steps to reproduce: 1. Login via lightdm 2. Open a terminal. 3. Run "echo $PATH" Expected result: the path contains the folder /usr/games like on earlier releases of Ubuntu. Actual result: PATH does not include /usr/games In addition, this causes PATH to not be set correctly after sudo. For instance, /usr/sbin is not in path after sudo. Once again, downgrading lightdm resolves the problem.
