I'm getting the same symptom - more often than not getting dropped to the low-graphics alert during startup - and the change to /etc/init/lightdm.conf listed above has *not* made a difference. This behaviour is consistent across several different machines. From googling around this bug seems fairly prevalent, and is graphics vendor/chipset agnostic which supports your reasoning above. However as noted the prooposed change hasn't helped me.
Looking through logs in /var/log/lightdm the only thing that stands out is in the greeter logs e.g. for a failed start: No protocol specified No protocol specified ... (unity-greeter:2340): Gtk-WARNING **: cannot open display: :0 No protocol specified ... I'm happy to try out other ideas for fixes as this is a show stopper for a desktop environemnt refresh under way at work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/969489 Title: lightdm tries (and fails) to start too early?
