I'm not sure what LightDM issue you're referring to, but I do believe similar issues with gnome-settings-daemon dying at any time will cause a loss of the theme.
However I have tried to be careful to distinguish between different error codes because there could be multiple bugs. In my case, if the theme is missing when I log in then .xsession-errors always shows that gnome-settings-daemon had the codes: "error_code 8 request_code 3 minor_code 0" -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/873545 Title: No GTK theme applied on login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/873545/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
