The Xubuntu login screen fails to appear after boot. It is possible to log in on the console at Ctrl-Alt-F2. Before running update and rebooting, the login screen appeared normally. When logging in on the console, the following error messages appear (they are also in dmesg): systemd-logind[965]: Failed to start unit user@112.service: Unknown unit: user@112.service systemd-logind[965]: Failed to start user service: Unknown unit: user@112.service ... systemd-logind[965]: Failed to start unit user@112.service: Unknown unit: user@1000.service systemd-logind[965]: Failed to start user service: Unknown unit: user@1000.service Strangely, the login screen sometimes appears after about 15 minutes.
