As a work-around for anyone else affected, I found that adding the following code to /etc/profile after the initial comments fixed it. I got this from the askubuntu article but had to add an addition /sbin to the user (non-root) path (else clause).
if [ "`/usr/bin/id -u`" -eq 0 ]; then PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" else PATH="/sbin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games" fi export PATH -- 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/1263736 Title: lightdm-session fails to login after update Status in “lightdm” package in Ubuntu: New Bug description: Similar to https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/962270 but exact errors differ, and I have no user customized ~/.bash* files so that is not the problem. (/etc/profile and ~/.profile are original as well) Cannot login graphical shell Unity as primary user. Can login as Guest. .xsession looks like this: /usr/bin/lightdm-session: 1: /etc/profile: id: not found /usr/bin/lightdm-session: 12: [: Illegal number: /usr/bin/lightdm-session: 1: /usr/sbin/lighdm-session: ls: not found /usr/bin/lightdm-session: 104: exec: ghome-session: not found As sudo I edited lightdm-session and put in some full paths; it only results in more downstream path errors. I could pound through all of them I suppose, but someone needs to triage this. askubuntu has an article on this bug, it suggests checking id and adding a path at the top of /etc/profile will fix it. However this distro still needs a fix. http://askubuntu.com/questions/336619/not-able-to-login-through-gui- in-ubuntu-12-04 Since this is a box-stock 13.10 install and blew out after an update, I am filing this as a bug.
