Here is the start on: start on ((filesystem and runlevel [!06] and started dbus and (drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1 or stopped udev-fallback-graphics)) or runlevel PREVLEVEL=S)
I suspect drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1 or stopped udev-fallback-graphics is emitting too soon. here is udev-fallback-graphics: start on (startup and (graphics-device-added PRIMARY_DEVICE_FOR_DISPLAY=1 or drm-device-added PRIMARY_DEVICE_FOR_DISPLAY=1 or stopped udevtrigger or container)) That bare 'card0' on the drm-device-added event is quite puzzling. Is it possible that it is simply matching as 'drm-device-added' and a second, non primary graphics chip is causing the issue? That might explain it. The timeline for these events is pretty complex so it will likely take some deep thought. Nothing in the upstart man pages suggests this syntax, event, bareword, variable, is valid or what it might mean. It seems to have been cargo culted to KDM as well, and come from gdm in lucid originally. Can somebody who is affected try removing 'card0' and see if that fixes the problem? I suspect this might be related to bug #936552 which also has to do with lightdm seemingly starting too soon. -- 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/969489 Title: lightdm tries (and fails) to start too early? Status in Upstart: New Status in “lightdm” package in Ubuntu: Confirmed Bug description: Sometimes lightdm comes up fine. Other times it appears to fail. x-0.log shows it tried to load 'nv' (rather than 'nvidia' which is what actually exists). When I then log into console and 'start lightdm', it comes up fine (on :1). I've not had it come up ok today, so I don't know if, when it comes up fine, it starts on :0. No idea if the lightdm.conf needs a change to 'start on'clause, or if this is just a case of a bad shipped config file (for module 'nv').
