Help Configure lightdm-gtk-greeter
Posted: Sun Jun 22, 2025 9:15 am
by operadude
A VERY minor issue, but I would like to solve it:
In my MX-Minimal 23.6 install, I cannot modify/edit the lightdm-gtk-greeter.
When I try to add a background and/or user image, I get the following error:
Code: Select all
LightDM does not have permissions to read path: /home/opera-dude
Here's my QSI:

A VERY minor issue, but I would like to solve it:
In my MX-Minimal 23.6 install, I cannot modify/edit the lightdm-gtk-greeter.
When I try to add a background and/or user image, I get the following error:
Code: Select all
LightDM does not have permissions to read path: /home/opera-dude
Without doing any other changes, maybe just this:
Give lightdm read permission of user's home folder with:
Code: Select all
setfacl --modify=group:$(id -g lightdm):r-x ~
What it does: It set's an addtional acl "Acccess Control List" property
which grants the special user "lightdm" read access of the user's home directory.
Check/verifiy with:
may show something like:
Code: Select all
getfacl ~
# file: home/opera-dude
# owner: opera-dude
# group: opera-dude
user::rwx
group::---
group:lightdm:r-x

@fehlix Thank You for Replying
However, when I try both of the above, bash complains:
Code: Select all

bash: setfacl: command not found
and...

$ getfacl ~
bash: getfacl: command not found
I did try this before I read your post:
MX-Tools -> User Manager -> Group Membrship (Tab) -> Check/Select "LightDM"
(By default, it was NOT checked).
Rebooted...
--> NO CHANGE!

Maybe your "respin" is missing an "important" package, which got normally installed with MX Linux.
and both are available at /usr/bin/setfacl and /usr/bin/getfacl
Perhaps, this
may help.

@fehlix Excellent
Installed "acl".
Now, I have these results:

I'm assuming that I will have to reboot for changes...
Trying without reboot...NOPE...
Will Reboot Now...

Kinda Works...
When I get the login screen, I Now have the picture (User Avatar) I want that is next to the user name.
However, when trying to edit the lightdm-gtk-greeter settings, I cannot modify neither the background, nor the user, image...???
An additional (related?) issue:
when I click-on to edit my "mugshot" (user avatar) in the "Application Menu", I get this error:
Code: Select all
Failed to execute child process "mugshot" (No such file or directory)
I want the same picture for my "mugshot" that I am using for the picture on the login screen, but the system is reporting that there is no "mugshot".

We Have a Winner:
@fehlix 
Strangely, it took 2 reboots, but now when I log-in, at the Greeter Screen, I have both the Background image that I chose, and the User image that I chose in the LightDM settings.
I still have the 2 problems of:
1. Not being able to edit the LightDM GTK+ Greeter settings, and
2. Not being able to edit the "Mugshot"
But, I consider those separate issues, and will mark this one as SOLVED.
Re: Help Configure lightdm-gtk-greeter

#2 Above SOLVED:
"mugshot" was NOT installed.
Now installed, and now can easily click-on the picture in the Whisker/Application Menu, and make any changes I want.
Oh, and most importantly:
I came to the solution via the Forum-- just searched for "mugshot", and found some posts with the same issue: inability to edit "mugshot", because it wasn't installed !!!
Once again, the Forum to the rescue

I noticed the same with MX 23.6 a week or two ago when wanting to change the default background in lightdm-gtk-greeter to a different one.
I ended up just copying the image to a folder lightdm-gtk-greeter had permissions to use, in this case /usr/share/lightdm-gtk-greeter-settings.

@operadude No probs.
Just for the record I was using a regular install of 23.6 but had the same LightDM permissions message you got.
Seems there's now a couple of apps have had similar things changed with MX-23.
Earlier today I installed imwheel and found there was no longer the file ~/.imwheel.rc created when installed.
Searching I found what appeared to be the only copy of it in the /etc/X11/imwheel/ folder, and it didn't seem to do anything.
Setting imwheel to run at login in Session and Startup and rebooting nothing changed.
So I copied the ~/.imwheelrc file from my MX-21.3 to ~/ in 23.6 logged out and back in again and all is well, it now works as expected.

@JmaCWQ Thanks for that!
I think I'm gonna open-up a new thread about the whole lightdm issue on my MX-Minimal install.
I DO NOT have any problems with lightdm on my other distros, all MX23.6 (Fluxbox, KDE, Xfce).
At this point I'm assuming my issue is that, as advertised, MX-Minimal comes with...wait for it...a "Minimal" number of installed packages. That still doesn't explain it to me, since I checked my Minimal install, and "lightdm" IS installed. So...yeah...a CONUNDRUM; or, an opportunity to learn more about Linux

Yeah it is a mystery and the message we both received seems to indicate a permissions issue of some type.
I only have the one install of MX-23 Xfce and this is the first install of any MX version I've seen this permissions message when changing the background image of the greeter, usually it's open the settings, enter password, edit whatever then Save.
With all my previous MX installs, during the install process I have always filled in the password etc. for both user and root accounts.
I'm pretty sure when I installed MX-23 that I didn't do that, and left the password etc. for root blank.
I wonder if that may have something to do with it?

Great Minds Think Alike
:
At some point I wondered the same thing
My Minimal install is the ONLY one (of the 4 MXs) where I DO NOT have a "root" account...
It still seems strange to me that I get that error, even though I have to open the LightDM GTK+ Editor with root privileges.
What's even more perplexing to me is that it seems, based on
@fehlix's solution (post I marked as "[SOLVED]"), that I enabled "lightdm" to read my home directory. And, even more perplexing than that, IT WORKED!-- I now have the background and user image that I selected, even though the lightdm dialog box says that it has no permission to read my home directory !?!
You reminded me that I was going to ask Fehlix if the CLI command that he gave me should INCLUDE write permissions, not only read and execute permissions. I guess I could try and see what happens.
Although, for now, it is "fixed" (enough) for me, since I don't plan on changing those images.
To be continued...

Nothing to be confused. the lightdm-settings-editor simply checks only standard read permissions ( those which you see with ls -l as "rwx------+" on the home-directory,
and assume user "lightdm" does not have read-permissions. They simple miss to check the POSIX ACLs (indicated by the "+" sign) , which is a standard feature of ext4. So kind of "bug" of the lightdm-settings-editor.

lightdm does not and will not write anything into users home. So setting read permission in order to access wallpaper-pictures is enough, either through ACLs or by adjustin this fairly protecting "rwx------", which is default in MX-23 for some time now.

@fehlix Thanks for the reply !!!
I'm in Xfce right now; will logout, and log back in with my Minimal install, so I can paste an image of the error.
It is not an error, per se; rather, in the LightDM GTK+ Greeter dialog box, pulled-up via the Whisker menu, when I try to change the Background image, or the User image, there is a little "i" (for information) in the dialog box (next to the words "Bacground" & "User image").
When I hover over the "i", it shows the error (lightdm does not have permission to read /home/opera-dude).
Logging out now, and will be back with a pic !

Ah,, that was explained already, it's a "bug" (or limitation) of the lightdm-greeter-settings editor, to not "properly" check permissiosn the user "lightdm" has, as they do "wrongly" not check the "real" permission provided by both the classical + ACL permissions. So just ignore that shown info line, as we know that false positive.

@fehlix OK, will ignore it.
BTW, I took some screenshots of that "error". I DO NOT get this "error" on my other installs of MX23.6 (Fluxbox, KDE, Xfce).
Now that I look at it, I can change the background image, and I think the User image, if it's formatted correctly (small enough).
Anyway, here are the screenshots I took:
Look for a "message" under where it says "Background" in the dialog box:
Look for a "message" under where it says "Default user image" in the dialog box:
Like I said in my earlier post, I consider this issue "[SOLVED]".
Thanks for your help
