I don't believe this is related at all to lightdm, more likely your graphics driver. I'm going to move it there, but mark it Incomplete. Can you please add the version of the xserver you are running and also attach your full /var/log/Xorg.0.log?
Also if this is resolved, please mark it Invalid. Thanks. ** Changed in: lightdm (Ubuntu) Status: New => Incomplete ** Package changed: lightdm (Ubuntu) => xorg (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040072 Title: too big background, crashes lightdm to CL.
