Here is the file. I've just attached this now as the issue happens each time. (If you select different users, sometimes on selecting several different ones, you cannot use the mouse, only the keyboard).
** Attachment added: "/var/log/lightdm/lightdm.log" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/886924/+attachment/2588581/+files/lightdm.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/886924 Title: Xubuntu Greeter (LightDM GTK) very glitchy Status in Light Display Manager: New Status in Xubuntu: New Status in “lightdm” package in Ubuntu: New Bug description: The LightDM gtk greeter is generally very glitchy. When selecting different users, the interface sometimes freezes, so you have to re- load lightdm from a tty. Sometimes, the user selected is 'stuck on', preventing other users from being selected. Also, the power and accessibility buttons cannot be used if different users are selected. This is not a lightdm fault, as the standard ubuntu theme for Lightdm works fine.
