    Not working here, I still see “Guest” on the login screen.
    I’ve edited the file, saved it, restarted lightdm, but the Guest is still there.
    Any ideas?

      29 mars 206&##8210;Immobile&78217; reste un des mes trois albums en francais préférés même si le groupe était, pour moi, décevant live.L’album solo de Valérie Leulliot m’a franchement déçu, peut-être parce que j’en attendai trop donc je n’ai pas pris de place pour les concerts. Avec quelques regrets…
