Bug description:
Impact
------
Files in the /etc/X11/Xresources directory stopped being automatically
loaded into the X resource database by GDM.
This typically causes changes in the user interface of multiple
programs; There are also parameters for fonts, including sclaing
(Xft.dpi) and mouse pointer size (XCursor.size). There is of course no
exhaustively listing the impact as each program can use arbitrary
entries in the database and alter its behavior as desired, not only
limited to the GUI (e.g. XTerm*saveLines).
Test case
---------
*Install the GDM update from proposed.
*Create the file /etc/X11/Xresources/m with the following contents:
XTerm*Foreground: white
XTerm*Background: darkblue
*[This will kill your graphical session in a standard Ubuntu setup] Execute
'systemctl restart gdm'.
*Log in as usual.
*Start XTerm.
XTerm launches, has a dark blue background and a white font.
Regression potential
--------------------
The main potential here is that files in that directory that were not
loaded before (because they did not match a pattern) would now be.
Original report
---------------
After upgrading from 21.04 to 21.10, my /etc/X11/Xresources/ directory
no longer loads on login.
Looking at the sources, I think this can be traced to:
- Switching from a custom Xsession file to the upstream Xsession file in
3.38.0-1ubuntu1, combined with
- An oversight in `debian/patches/ubuntu/xresources_is_a_dir.patch`
Looking at [that patch](https://salsa.debian.org/gnome-
team/gdm/-/blob/ubuntu/master/debian/patches/ubuntu/xresources_is_a_dir.patch),
it has:
```diff
--- a/data/Xsession.in
+++ b/data/Xsession.in
@@ -122,6 +122,13 @@ fi

+ fi
+ done
fi
if [ -f "$userresources" ]; then
```
However, looking a few lines further up in [the original Xsession.in
file](https://salsa.debian.org/gnome-
team/gdm/-/blob/ubuntu/master/data/Xsession.in#L97), I see:
```sh
if [ -f /etc/X11/Xresources ]; then
sysresources=/etc/X11/Xresources
else
sysresources=/usr/etc/X11/Xresources
fi
```
In other words, if `/etc/X11/Xresources` is a directory, the
`sysresources` variable is never set correctly, so the patch should
also modify this part of the script.
I have observed this broken behavior on version 41~rc-0ubuntu2, but
looking at the ubuntu/master branch (as linked above), it still seems
broken there.
I'm currently testing this patch:

I don't know if it works yet, since I need to log out for that, and
close my browser, so need to submit this report first ;-)
