Anyway, I just tried to add my user to group gdm, no change. |

It's gdm, by comparison with another system where gdm starts fine it is |
| 26 |
normal. |

I tried to set the /var/lib/gdm permission to 1777, no change. |
| 41 |
Finally I cleared the /var/lib/gdm contents, no change. |

Going back to the error log: |
| 44 |
|
| 45 |
systemd[356]: user@××.service: Failed at step PAM spawning |
| 46 |
/usr/lib/systemd/systemd: Operation not permitted |
| 47 |
|
| 48 |
I believe that systemd is telling me that PAM did not allow spawning a |
| 49 |
'/usr/lib/systemd/systemd' for user gdm. Maybe I should try to |
| 50 |
understand why PAM is denying it. Anyone expert with PAM? |
