[gentoo-user] User group problem

[gentoo-user] User group problem

[Anthony E. Caudel]

I sometimes have to add my user to a group. This of course doesn't take
effect until I log out and back in.   However, if I'm under X, I can't
logout without first exiting X.

So, I'm wondering if there is any way to re-log the user without exiting X?

Not really.  (please someone correct me if I'm wrong)

However, if you are using a terminal to launch an application and using "bash 
-l" for that terminal application then anything you start will show the new 
group.

If you are instead just launching from the applications menu in your desktop 
(kde, gnome, blackbox) then you have to log out of X then log back in.

Maybe I'm not doing something right.  From KDE's konsole, I invoked a
new shell with "bash -l" and then ran "id" but it did not reflect the
new group.

No you did nothing wrong.  I double checked it and it's as I feared.  You have 
to log out and back in for the changes to be reflected.  Any new logins will 
reflect the group change, but not existing ones.   If you ssh into your 
system that login will reflect the new group, just as if you logged out and 
back into X the changes will be reflected.

This is a shortcoming of the Unix strategy for dealing with users.  They are 
immutable after they log in.

You can do

% newgrp <groupname>

and the shell that it is executed in will then show the change.

% groups

will prove that you are in the group currently.

But in order for new terminals that you spawn from an X session to have
the new group you must log out and log back in.  That is correct.
