This bug hit me after an upgrade from 14.04 to 16.04.1. Strangely I was not affected earlier. Maybe a reinstall might fix this issue? Two out of three reboots leads to failsafe X. Sleep command improved the situation but still 50%... Other solutions like restart in rc.local somehow did not work. Maybe systemd is ignoring it or it is executed way to early. Maybe this bug is related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1070150 ?
gdm3 currently only comes up with a black screen and a mouse cursor and no error in the logs... sddm is working fine but the lockscreen locks the terminal permanently and only killing the process on tty1 unlocked it. Current workaround with a newly created systemd service which starts after the graphical target is completed. (see attached file) systemctl enable lightdmrestart systemctl reboot Currently working without an issue. Hope it helps if someone else is still affected and needs a quick fix. ** Attachment added: "Verbose burgreport and service scripts" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/969489/+attachment/4733512/+files/bugreport-lightdm2.txt -- You received this bug notification because you are a member of Ubuntu Touch seeded 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 : Confirmed Status in lightdm package in Ubuntu: Triaged 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').
