Lxde graphical session won't autostart - User Manager service fails

Hello

I can't tell when the issue has started because up to this point i mostly set my machine to sleep when unused and had a couple of system updates in the meantime. I just found out about the problem when i was forced to reboot my PC. Then i am forced to log in on tty to manually execute startx.

My system is up to date.

 $ systemctl --failed
  UNIT              LOAD   ACTIVE SUB    DESCRIPTION              
● user@1000.service loaded failed failed User Manager for UID 1000

 $ journalctl -b -u user@1000.service
-- Logs begin at Sat 2018-04-28 08:16:55 CEST, end at Sat 2018-06-02 20:31:54 CEST. --

cze 02 19:03:01 daedalus systemd[1]: Failed to start User Manager for UID 1000.

I have tried to set up this variable with ~/.profile ~/.bashrc to no avail and don't even know how to go about solving this problem.

What other info would be helpful?

Re: Lxde graphical session won't autostart - User Manager service fails

Post a full journalctl -b that variable is automatically set if your session starts up properly, remove your manually added references. How are you attempting to autostart in the first place?

Done.

I don't fully understand the whole process but at some point this service should be executed but i think it fails on user manager service

# xinit@archer.service
[Unit]
Description=startx for user %i
After=x@vt7.service systemd-user-sessions.service
Wants=x@vt7.service
Conflicts=getty@tty7.service

# user@.service
[Service]
User=%i
TTYPath=/dev/tty7
PAMName=login
Environment=DISPLAY=:0
WorkingDirectory=/home/%I
Nice=0
ExecStart=/bin/bash -l -c "cd; startx >/dev/null 2>&1"

[Install]
WantedBy=graphical.target

[Unit]
Description=User Manager for UID %i
After=systemd-user-sessions.service

[Service]
User=%i
PAMName=systemd-user
Type=notify
ExecStart=-/usr/lib/systemd/systemd --user
Slice=user-%i.slice
KillMode=mixed
Delegate=pids memory
TasksMax=infinity
TimeoutStopSec=10s

This is what i get when i manually execute line under ExecStart:

[ 10:01 ]  [ archer@daedalus:/usr/lib/systemd/system ]
 $ /usr/lib/systemd/systemd --user
