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 lead 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. Sleep in
/etc/init/lightdm.conf improved the situation but did not fix it.

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, only
killing the process on tty1 unlocked it.
Current workaround:
$ cat /etc/systemd/system/lightdmrestart.service
[Unit]
Description=Restart lightdm
After=graphical.target
Wants=lightdm.service accounts-daemon.service
[Service]
Type=oneshot
ExecStart=/usr/local/sbin/restartlightdm.sh
[Install]
WantedBy=default.target
$ cat/usr/local/sbin/restartlightdm.sh
#!/bin/bash
sleep 2
CHECK=$(ps axu | grep "/bin/bash /usr/share/xdiagnose/failsafe[X]init
/etc/X11/xorg.conf.failsafe")
if [ ! -z "$CHECK" ]; then
ps axu | grep "/bin/bash /usr/share/xdiagnose/failsafe[X]init
/etc/X11/xorg.conf.failsafe" | awk '{print $2}' | xargs kill
sleep 2
systemctl restart lightdm
else
exit 0
fi
systemctl enable lightdmrestart
systemctl reboot
Currently working without an issue. Hope it helps if someone else is
still affected and needs a quick fix.

Some systems are intermittently booting to a black screen or message

and Nouveau driver still unconfirmed.

There are currently three known workarounds to this issue:
1) Log in with CTRL+ALT+F1 and issue command "sudo service lightdm restart"
2) Add some sleep to /etc/init/lightdm.conf
3) Install and use GDM instead of lightdm
