It seems though it can be guessed more or less what can cause problems (ie thinkpad + lightdm + systemd) the exact details are not the same, and some other conditions can/do count as well. Also the "not always" factor sometimes, kinda odd.
However, as bug 1340964 if often referenced for me, and it is about some kind of VT activation problem, can it be because some race condition on using VTs or such? Since systemd may do deeper parallelism on the boot process than upstart (I am not sure just guessing) or at least it did it not the very same way, it can explain why it works with upstart but not with systemd. But really, I am just guessing, and trying to give hints, as release data for vivid is coming and this bug still exists rendering ubuntu totally unusable for normal users on some hardware like some thinkpad notebooks which are not so rare, I think. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1434396 Title: Xserver does not start on boot (low-graphics mode) To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1434396/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
