You'd have to always indirectly start an intermediate "gnome launcher"
thing (instead of the real program) that sets up the environment, then
exec the real program for that to work.

No, that would not be necessary at all. Think about how GNOME Terminal 
and GNOME Editor work. As I said: These are already passing a whole 
bunch of process state from the client to the server, in order to 
preserve things like the apparent semantics of GNOME Terminal windows 
"inheriting" the working directories of the invoking clients, when in 
reality there is no inheritance from those client processes going on at 
all. This would be just one more such item of process state.

Have you tried to set in /etc/pam.d/login this:

session optional pam_umask.so umask=0077

Logout and login back after that?

#184823

I have created a file named ".xsessionrc" and it is in my home folder (~/.xsessionrc). Within this file I wrote this: umask 077.

No change is evident. I first tried a relogin. No effect. I then rebooted. Also no effect. Creating documents still results in rw-r--r--.

(I am logging in with gnome display manager and opening documents from the gnome-shell interface, not from a terminal).


Is there a specific entry that I should have made in the ~/.xsessionrc file? Should I "undo" the entries I made at /etc/login.defs and/or ~/.profile? Those are still set to 077 as I mentioned previously. So I have /etc/login.defs, ~/.profile and ~/.xsessionrc all with entry "umask 077". But the result is rw-r--r--.

OK, you're not going to give us any details without tooth-pulling.
That sucks.  I will have to rely upon guesswork.

You used the word "login" and the word "gedit".  This tells me that you
may be concentrating, currently, one of the two following scenarios:

1) You login locally through a display manager into an X session.

2) You login locally on the Linux console and use startx to launch
   an X session.

Now, we can probably rule out #2, because you claim that modifications
to ~/.profile did not work.  There are various situations where you
*could* still be using console login + startx and have your changes in
~/.profile not take effect, but the simplest answer suggests you are
not doing that.

So, you're probably logging in through a display manager.

If you want to configure the X session that you get when logging in
through a Debian display manager, use the file ~/.xsessionrc
instead of ~/.profile.

See <https://wiki.debian.org/Xsession>.

Yes, Virginia, ~/.xsessionrc does not exist by default.  You would have
to create it.  (These days, users have to be *told* this for some reason.
They whine and moan if you don't reassure them that yes, it's OK that
a file doesn't exist and that they should create it.  Sad but true.
And this user top-posted, so I'm inclined to suspect he/she falls into
that group.)

No, I am not talking about ~/.xsession.  ~/.xsessionrc is a totally
different file.

Easiest way to verify it would be to open a terminal and run "umask".

In that case, it sounds like GNOME is overriding your umask.  You may
have to ask a GNOME support list how to work around this.  The first
Google result I found suggests adding it in ~/.gnomerc instead (in
addition to a crapload of obviously, blatantly *wrong* answers, as
usual).  I don't know whether .gnomerc will work, but you can try.

Rebooting would not matter.  The ~/.xsessionrc file is read by the
Debian X session when you login.  The problem is, anything you set there
can be changed later, e.g. by GNOME.

I tested it just now on my system, creating a ~/.xsessionrc file
containing "umask 002", and then running "startx -- :1" from tty2.
This gave me a(nother) X session, in which the umask was set to 002 as
expected (confirmed by running umask in a terminal).  But I don't
use GNOME.  I just use a window manager, fvwm.

#184826

Terminal confirms my umask is 022. That is, my entries at login.defs, xsessionrc, etc are not working.

Thank you for your assistance, Greg. Before asking here, my research indicated gnome is the problem and it is because of systemd that there is a problem. I assumed because gnome is default on debian, you might have some insight. 

Thank you for your efforts, much appreciated.

Depends on terminal. If you use xterm under Gnome, it will respect umask
settings, wherever those are, global or local in .profile or .bashrc.
But gnome-terminal does not respect those settings. Guess that you
should file bug against gnome.

If gnome-terminal is reading .profile, that means it must be running
your shell as a login shell, which is a questionable practice.

Yet another strike against GNOME, if true.

I run all my shells in terminal as login shells, because I prefer it
that way. If you do not like it, do not do it :P It has nothing to do
with Gnome.

Ehh, disregard please. Just checked with gnome-terminal here, and it did
respect umask settings in .profile. But gedit did not.

Parts of this paragraph are not correct.

Putting a umask command in .bashrc would cause it to be run every time
you run a non-login bash shell, for example by opening an xterm, or a
new tab inside a gnome-terminal.  That particular instance of bash would
have the umask that you expect, because it's overriding the terminal's
umask due to the command it reads in .bashrc.

But the OP was trying to get gedit's umask to be different, and I'm
guessing (s)he's running gedit directly from GNOME, e.g. from some
kind of drop-down menu or hotkey, not by typing the gedit command in
a terminal.  Thus, gedit only inherits the umask from the window
manager (or whatever its parent is), not from any instance of bash.

To set umask of the window manager (or whatever), the instructions I gave
previously should work.  They do for *my* window manager.  But GNOME
may unilaterally decide to *change* the user's umask to whatever GNOME
decides is a correct value.  We've seen other unsolvable questions from
GNOME users here, e.g. one person was trying to set LC_* locale variables,
and GNOME just blew them away.  I don't believe we ever found an answer
for how to make it stop doing that.

Anyway, GNOME is a disaster, with the software assuming that it knows
better than you what you want, and with (apparently) no way to tell
it how to act differently.

Fortunately we have lots of other choices.

Like any .local file, it's an optional file. Any .local files that may exist by
default have uncommented content only if the /local/ admin creates any.

There is nothing in Debian's /etc/profile which reads such a file.

Debian's /etc/profile does, however, dot in all the files in
/etc/profile.d/.  No, wait.  Not all the files.  Just all the files
that end with a .sh suffix.  And you'd better not put spaces in the
filenames either, because there's a blatant bug right here:

  for i in /etc/profile.d/*.sh; do
    if [ -r $i ]; then
      . $i
    fi
  done

I don't expect anything better; that would be foolish optimism in
violation of decades of historical precedent.

The umask *of what*?  Of login shells?  Of files uploaded via ftpd?
Of files uploaded via sshd/builtin sftp?  Of desktop environment sessions
started from a display manager?  Of some random cron job?
