User icon not updated in login screen

[snow]

I created 2 users. The first and the second user have their own user pictures.
When start the laptop and see the login dialog I see the first user picture, but the second user picture is the standard icon (women head profile), but not the picture I assigned to the second user. So, the seond user picture does not get updated in the login screen.

Please check that the image file is world-readable. You can do that in a shell by running:

   chmod 644 YOURFILE

or in Files:

   Properties > Permissions > Others: Access = Read-only

I did it. No change.

More infos:

The user icon of user 2 is in /home/pictures/ folder of user 1.
The icon is shown for user 2 when she is logged in or logged out. So it has access to the picture, but on the main login dialog with all users the icon of user 2 is not changed.

And I do not understand why "chmod" is necessary when I add the picture via the user maintenence dialog. It it works via the dialog it should be accessible.

[snow (mrauschert)]

the user 1 is the user with system admin rights. user 2 is a standard user.

[Daniel van Vugt (vanvugt)]

The login screen runs as a different user, not as "user 1" or "user 2", so it can only display world-readable image files.

I wonder if you also need to:

  chmod 755 ~/Pictures

to make the directory readable too.

If you still have any problems then please run this on the file:

  stat YOURFILE > stat.txt

and attach the file 'stat.txt' here.

[snow (mrauschert)]

Noch change. And I again noticed that after switching the user sessions I land on the command line without a desktop. But this is what described in another bug. This whole user session switching is not stable on Kubuntu/AMD.

I attach the stat.txt file.
