I am using Ubuntu 14.04 LTS 64 bit . I know this question has popped up many times but I want to make it very clear that none of the posts helped me a bit.
my Problem: I am unable to get my custom wallpaper stored at /home/sudeepto/Pictures on the Ubuntu login screen . The screen shows me purple background and upon giving login credentials the graphics gets really scrambled for a while and then I can use my system just fine.
I guess since most of the articles are not Ubuntu 14.04 based, I am having such problems.
Things that I tried:
I followed this post on askbuntu . I tried both the suggestions but no luck.
I don't know how to take screenshot of unity-greeter, otherwise I would have given links to my login screen as well.
Please tell me what should I do next to solve this problem which I never faced in previous versions of Ubuntu.
