Délai d'initialisation de l'environnement de bureau en 20.04 (aide s'il vous plaît!)
Spécifications
Gestionnaire d'affichage: lightdm 1.30.0
Environnement de bureau: gnome 3.36.3 (Bien que j'ai aussi essayé xfce)
Problème/fond
Une fois que je me connecte, tout ce que je peux voir (pendant au moins une minute) est le fond d'écran et la souris. Finalement, le reste de l'environnement de bureau est chargé et tout est bon à partir. Si je me déconnecte et de retour, je n'ai pas le même problème que je fais au démarrage. En outre, je ne peux pas utiliser de tty pour savoir ce qui se passe car la connexion à la TTY prend pour toujours - peut-être un problème connexe (authentification)?
À l'origine, je pensais que le problème était lightdm mais il s'avère si je passe à gdm3 J'ai le même problème sauf au lieu de voir le Walpaper et la souris que je viens d'avoir un écran noir. Je suis maintenant convaincu que le problème réside dans le gnome de.
Tentatives
- Installation de
haveged - Désactivation de la
lightdm.serviceetstartxing - Désactivation/retrait des extensions de gnome
- Installation/utilisation de
gdm3 - Installation/utilisation de
xubuntu-desktop - Utilisation des pilotes vidéo exclusifs NVIDIA et NOUVEAU
- Mise à niveau vers 20.10 Gorilla Groovy (essayant actuellement - mettra à jour si fonctionne/ne fonctionne pas)
Journaux [édité]
J'ai pris une approche plus ciblée et dès que je suis entré dans mes identifiants de connexion vers 15:06:20, j'ai chronométré la durée de l'initialisation (~ 58s). Tous les journaux ci-dessous sont extraits de journalctl dans ce délai et les trois premiers sont adaptés à une catégorie spécifique.

Désactiver networkd-dispatcher
De - reddit :
Désactiver les services NetworkD:
Si vous n'êtes pas un administrateur système, vous n'avez pas besoin de cela. Gui utilise Network-Manger (et il a son propre répartiteur) de toute façon.
Sudo apt-get remove networkd-dispatcher
Sudo systemctl stop systemd-networkd.service
