Changing the login screen resources (background,icon) fails when EncryptedHome is used and resources are in ~

[Ronan Jouchet]

The "Login Settings" module seems to work fine (no console output either), but the background change isn't effective (worse, it removes the standard background, resulting in a solid purple background).

Ubuntu 10.04 final x86-32, installed from a desktop cd, UbuntuTweak 0.5.4.

Please upload a screenshot of the Login Settings, thanks.

Here is a screenshot showing login settings in Ubuntu Tweak and in the "Login screen" configuration panel.

And here is a photo showing the login screen.

Additional comment: using the "revert" button to come back to /usr/share/backgrounds/warty-final-ubuntu.png works.

What is the path of background image?

/home/ronj/Pictures/_wallpapers/fiftyfootshadows/dust_3.jpg

Put your dust_3.jpg under your /home/ronj, then try again.

I know! I am using Ubuntu encrypted home. So actually /home/ronj doesn't even exist when gdm looks for its wallpaper. At this time, there is only gibberish /home/.ecryptfs, waiting to be transparently mounted to /home/ronj by ecryptfs when I enter my login passphrase.
Have a look at the implementation details by Dustin Kirkland: https://help.ubuntu.com/community/EncryptedHome

Possible solutions I can think of:
- always do a copy of the file out of ~, like /usr/share/backgrounds/ubuntu-tweak-gdm-background.EXT
- when EncryptedHome is detected, do a copy of the file out of ~, like /usr/share/backgrounds/ubuntu-tweak-gdm-background.EXT, warning the user the file has been copied out of his home folder
- when EncryptedHome is detected, tell the user ubuntu tweak won't be able to change the login screen for privacy reasons, and explain manual steps

By the way, the title of the bug that I just changed reflects the fact that it affects also the login icon.
