Good point. And I notice that /etc/pam.d/lightdm talks about # Load environment from /etc/environment and ~/.pam_environment session required pam_env.so readenv=1 session required pam_env.so readenv=1 envfile=/etc/default/locale so experimenting with those files might be an idea. BTW I notice that /etc/security/pam_env.conf contains a line that can *set* the PATH, but only contains "PATH", not "PATH=". So I'm afraid the OP should be searching /etc for USER rather than USER=, even though this will output a lot more noise. Cheers, David.
