Changed my settings into "lightdm-gtk-greeter" to be able to select different languages at login each time I wish.
Everything is fine with my PC. It logins correctly after a while with an exception that background wallpaper is distorted as seen in the sample picture( http://imgur.com/Kpw2NET )
I installed Super-Boot-Manager and using it. Is it possible that Plymouth has caused into this?
How I can correct background appearance?
Thank you in advance.
