Reading your lightdm log, it seems LightDM cannot load seat0 for your case.
Do you have any custom config file under /etc/lightdm/lightdm.conf.d (or /etc/lightdm/lightdm.conf)? Specially, do you set option "start-default- seat=false" explicitly? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd-shim in Ubuntu. https://bugs.launchpad.net/bugs/1365039 Title: Could not get session id for session Status in Light Display Manager: New Status in “systemd-shim” package in Ubuntu: New Bug description: A few hours back we got two packages upgraded: systemd-shim (7.2) and lightdm (1.11.8-0ubuntu1). On that pc, i've closed the session then shutdown: everything was stable, and its a fresh standard installation using upstart for booting. Here are the troubles met at the next cold boot (verbosy mode): - the boot process goes well until "Add swap on /dev/sdb2" as expected, but then nothing, only hdd activity continuing hardly scanning, and no errors/warnings printed. Had to force a hardware's reset, can't call tty1-6 (system not responsive ??) - second cold boot: the system load fsck on the /home partition, then the process continue to boot, made a pause at load the swap partition again, the hdd was activity working a few (long) seconds, so i've tried to switch to tty1 and successed. I've reconfigured lightdm and tried startx : it seemed to continue its processes even if the hdd was again hardly scanning unsually. But i only got a black screen: no mouse pointer, no tty. So reboot again. - third try: same issue, but was able to open tty when it did a pause at swap partition loading: so i reconfigured lightdm and choose gdm as default that time. Startx was ran and after some hard hdd scanning, it finally loaded a degraded login screen: no mouse but the keyboard was working. After login validation, gnome-shell appeared as expected, but again no mouse; a ctrl+alt+T opened a terminal, where i'm right now, to report that issue.
