lenteur Ubuntu 20.04 (navigation internet, visio,...)

Bonjour,

J'utilise Ubuntu depuis quelques années déjà et lors du changement de mon laptop je suis passé de la version 18.04 à la version 20.04. Et après plusieurs jours d'utilisation je rencontre de gros ralentissements lors d'une utilisation basique de mon Pc.
J'ai tenté d'identifier les processus pouvant poser problème pour mettre à jour les logiciels ou réinstaller les logiciels posant problème. Même après une réinstallation complète je continue à avoir de gros ralentissements avec notamment Firefox qui me prendre 90% de CPU avec 3 onglets ouverts.

Pourriez-vous m'aider à diagnostiquer le problème?

Merci,

Hors ligne

Chose peut-être importante aussi le laptop est "docké" sur un dock DELL pour le branchement d'un deuxième écran.
Chose étrange, je viens d'installer gnome-session-flashback et même sans passer par une session Metacity, le PC est devenu beaucoup plus fluide. Mon CPU plus stable. Je ne comprends pas le lien.

Merci pour votre aide

Re : lenteur Ubuntu 20.04 (navigation internet, visio,...)

Hello la communauté,

Le problème est de nouveau présent. Je ne sais pas trop de quel côté chercher. Je me retrouve avec une lenteur globale dans n'importe quelle appli (slack/firefox/phpstorm). Si vous avez des outils ou des idées de manipulations à faire pour trouver l'origine du problème ça serait super.

Bonjour,

Fournis les noyaux présents :

echo; dpkg -l | awk '!/^rc/ && / linux-(c|g|h|i|lo|m|si|t)/{print $1,$2,$3,$4 | "sort -k3V | column -t"}' ; echo -e "\nNoyau courant : $(uname -mr)"

et :

dpkg -l | grep -v ^ii

en te servant du Retour utilisable de commande.
