Public bug reported:
The gdm3 package comes with a session launcher script /etc/gdm3/Xsession which
starts
everything up. In that script it unconditionally executes $HOME/.profile (if
it exists).
But this is not necessarily the correct shell startup file.
If your shell is bash and you have a .bash_login file, tty logins will use that
and
never touch .profile; but logins via /etc/gdm3/Xsession won't execute
.bash_login
and therefore will not set up your correct environment. If your shell is csh
then
.profile was never in the picture and you need to instead execute .login and
.cshrc
(which of course are in a different syntax that the /bin/bash which executes
Xsession
won't understand).
I understand this file comes from upstream, so the bug should probably be filed
upstream
as well. But Ubuntu doesn't have to include this Xsession in the gdm3 package
and
could supply its own. (Red Hat have written their own and supply it in their
xorg-x11-xinit
package; their gdm package simply symlinks that from /etc/gdm. They've solved
the
profile problem by making the script execute: exec -l $SHELL -c "[command]"
where
[command] is a shell command that starts up the session.)
In fact Ubuntu already does have a more comprehensive Xsession system included
as part
of the x11-common package. So the Xsession supplied with gdm3 is redundant.
(Unfortunately
that other Xsession also does not set up your environment correctly; it doesn't
seem
to call any profile at all.)
