Hello guys i just install Ubuntu 12.04 (amd64) as dual boot on mine Alienware M11x, actually install severals times because issues with the video card (Optimus) i have a dual boot with Win7 Ultimate 64 and Ubuntu

I cant find a way to change my login wallpaped (dotted), i have try "ubuntu tweak" and dont change anything

already try changing direct on lightdm (unity-greeter.conf) but didnt work, i read on askubuntu that unity used your current background as login screen but isnt working for me

Im a normal users trying linux i used redhat 4 LONG TIME ago and used only CLI no X11 :P

any tip about this ?

thanks in advance

Unity will use the same wallpaper as youa re using on your desktop, but the wall paper needs to be in the system-wide wallpaper directory (/usr/share/backgrounds) for that to work. LightDM can't access the wallpaper from inside the user's home directory.

I'm not sure about changing the login screen wallpaper manually, I'd assume unity-greeter.conf should do the trick but of course the same rule about the location of the image still applies.

LightDM can use whatever wallpaper the user has set, the only requirement being that the wallpaper just needs to be in the user's Pictures folder and the user has set the appropriate permissions for that folder, i.e. in the Permissions tab he/she has set the Folder Access for Others to Access Files and the hit the Apply Permissions to Enclosed Files button.

OK, that's good to know. Does it work only for ~/Pictures, or also for subdirectories? (I have way too much images to dump them straight into Pictures...)

There are many ways of doing this. I like the program Wallch. It should be in the repositories.

already install and configure Wallch, the main issue here was that i set the option to encript home folder, as far i have read on askubuntu and here :p

ty all for your help

You could move these pictures somewhere not encrypted (outside your home directory) and create a symlink in the home folder for convenience.

Just a thought...
