I use Ubuntu 12.04.
Recently, I change to use another Accounts Service which could remove certain users from the graphic login screen of unity-greeter. I downloaded source code from a branch of
https://github.com/mmonaco/accountsservice.git
which is named exclude-v3. After compiling and installation, things seem to work. However, I found that the background of unity-greeter is always that purple one, not my wallpaper as before. And when changing the highlight user name to login, the background won't change at all.
I have tried all of the following methods, but none of them seems to work.
1) Change my wallpaper and then change back to the original one, or
2) "gsettings set com.canonical.unity-greeter draw-user-backgrounds true"
or do that under the name of user lightdm
I also checked " /var/lib/AccountsService/users/myusername " to ensure the setting there is correct. I checked the permission of the wallpaper file, which is " -rw-r--r--" and belongs to me.
So is there anyone who can give me some advice on what next I could try, or should I directly contact with the one who works on that new branch? ( Actually it seems not that new according to the last commit date )
Thanks a lot!
