Bonjour,
Ton pc a un processeur très peu performant mais ça ne justifie pas une lenteur extrême et des plantages.
Tu as installé le bureau xfce sur Ubuntu ou bien tu as installé Xubuntu ?

Essaie avec Lubuntu en live-usb et vois si c'est aussi lent.
J'ai installé Xubuntu. Je trouve Xubuntu très simple d’utilisation.
Avec Lubuntu, le fonctionnement est le même ?
Normalement Xubuntu devrait tourner de façon à peu près fluide sur ton pc. Lubuntu est simplement plus léger que xubuntu.

tu peux donner les résultats des commandes suivantes ?
systemd-analyze
systemd-analyze blame
et
systemd-analyze critical-chain 


Fais de copié/collé ici.

Le temps de démarrage (45 secondes) est normal pour un pc avec un HDD.
Il faudrait vérifier l'état du disque dur qui pourrait expliquer les plantages et la lenteur de chargement des applications.
Lance l'application Disques et regarde les données smart du disque .
https://doc.ubuntu-fr.org/gnome-disk-utility#superviserreparer_les_disques_et_les_partitions
Sur la doc, ils ne disent pas comment installer gnome-disk

j'avais oublié, des infos supplémentaire:

Gnome-disk n'est pas installé ?
Dans le terminal:
sudo apt install gnome-disk


Qu'est-ce que tu as comme carte graphique ?
Tu devrais essayer avec le live-usb qui t'a servi à l'installer pour voir si tu observes les mêmes problèmes.
