Lags éparses

Bonjour,
Je rencontre quelques lags, surtout en début de sessio mais pas que..
Ce matin, freeze sur une copie d'écran et collage dans Gimp.
J'ai noté l'heure du freeze et me suis précipité dans les logs.
Pouvez vous trouver une incohérence qui expliquerait la situation ?

Bonjour,
Il faut lancer Gimp depuis le terminal : il semble avoir des problèmes soit avec la carte graphique soit avec le programme. Quelle carte graphique est installée ? Il y a aussi un chipset graphique sur la carte mère ?
Que retourne la commande lspci ?

Hello ;=)

Smart contrôle tes disques au démarrage.
Regarde l'état de tes disques au cas où : par exemple via gsmartcontrol, 
ou ici par exemple si tu veux passer par la ligne de commande : https://blog.microlinux.fr/check-disque-dur/




Tracker est lié à Gnome, il indexe des fichiers/données. Certains utilisateurs rencontrent des soucis de performance semble t'il, tu peut le désactiver si besoin :

Cela serait du à un bug de Qt :
