[pkg-cinnamon] Bug#784158: Bug#784158: cinnamon: GUI logons with cinnamon + lightdm do not source either /etc/profile or ~/.profile

[Maximiliano Curia]

Control: reassign -1 lightdm 1.10.3-3
Control: clone -1 -2
Control: reassign -2 x11-common 1:7.7+7
Control: severity -1 normal
Control: retitle -1 Missing pam_env.so user_readenv=1 in the pam file
Control: severity -2 normal
Control: retitle -2 Xsession script to process /etc/profile and ~/.profile

The reported issue is not specific to cinnamon, so I'm reassigning parts of
this to the lightdm package maintainers and the rest to the x11-common
maintainers.

The ~/.profile file is intended to be sourced by a login shell session, it's
not specified if it needs to be sourced by a X session, and it hasn't been the
default in most Debian desktop managers.

The documented way to add environment variables is using the ~/.xsessionrc to
add them when starting the X session (see Xsession(5)), or /etc/environment
and ~/.pam_environment to add them when login in via pam.

Sadly, the pam file distributed in the lightdm package is not processing the
/etc/environment and ~/.pam_environment file. Thus the reassignment of this
bug to the lightdm package.

Lightdm maintainers: please consider adding:
auth      required pam_env.so user_readenv=1
to the /etc/pam.d/lightdm conffile

I'm not sure this is a good idea, but I forward this part to the x11-common
package maintainers, so they decide whether it makes sense to add a Xsession.d
script for this.

Happy hacking,
