New wallpapers outside of default stack do not reflect in the login screen

[Abhishek Kharvadi]

Hello,

When a Desktop wallpaper is set to something which is not part of the default wallpaper stack, then the login screen defaults to purple default wallpaper screen instead of the new background selected. This causes to loose consistency which was the intended purpose to have the same login screen background for user as his desktop wallpaper.

Thanks.

I tested this by setting a downloaded picture as wallpaper. Upon logging out, the LighDM background image did display the same wallpaper.

@Abhishek Kharvadi:
Do you still have this problem?

Did you update your operating system?

What format and size is the wallpaper that you used?

Status changed to 'Confirmed' because the bug affects multiple users.

Where is the wallpaper you are using stored? is that file accessible to other users? the lightdm users can only display files it can read, if your user directory access is restricted that doesn't work, it's a known issue

Hello Sebastian,

The wallpaper is stored in ~/Pictures/Wallpapers/Originals. I have not
modified permissions on any of the folders. It uses default permissions.

I just copied a picture to my ~/Public folder and set it as my wallpaper
and it worked this time. It does seem permissions is the issue. It seems
related to the bug you mentioned.

Thanks :)

Here is a related discussion at UbuntuForums: http://ubuntuforums.org/showthread.php?t=1952241

Apparently, other people are experiencing that pictures or photos outside of the Picture folder are not being displayed in LightDM.

Here is a quote from odysseusjak: "After playing with this, I found that the image has to be in the "Pictures" folder and not in a sub folder. I have a "Wallpapers" folder within my "Pictures" folder. If i selected an image in the "Wallpapers" folder, it would not show up on log in."

Hi,

It works fine when the picture is in the "~/Pictures" folder directly
and not a sub-folder. Also, I just changed the wallpaper again and this
time, I set it from a sub-folder in ~/Public folder and again the purple
wallpaper was back.

So, you can have the wallpaper in either ~/Public or ~/Pictures and
lightdm would display the wallpaper at login just fine. Use any
sub-folder within these directories and purple background would return.

Thanks,
Abhishek

Hi, I'm using wallch to cycle my wallpaper. My greeter never reflect the wallpaper selection too.

[Alex Moldovan (alexmoldovan)]

Still happening in Precise, fresh install. I have even copied the wallpapers in /usr/share/backgrounds and applied the permission that other files there have but still they don't appear at login or in System Settings->Apperance. The only wallpapers that work are the default ones.

duplicate bug #928553?

[José Lou Chang (obake)]

Hi Sebastian, Yes, it does seem to be a duplicate of that bug report. I will mark it as one.
