Buona domenica a tutta la lista! Oggi, mentre sto salvando un testo, libreoffice write si chiude all'improvviso (mentre visualizzo una cartella di dropbox dove volevo salvare) Ripeto la cosa lanciando libreoffice da terminale ma l'intero pc diventa fortemente instabile, kdm si blocca. Riesco dopo qualche minuto a visualizzare una consolle ed entro come root. Leggo dei messaggi non rassicuranti di dmesg e provo a riavviare come consigliato all'ultima riga. Non riesce a riavviarsi, nemmeno con reboot, shutdown -F... quindi procedo, a malincuore, a resettare con il tastino, sperando di non procurare danni permanenti ai dischi. ora funziona ma senza effetti grafici... Più sotto allego l'estratto del dmesg. Non ci capisco molto, ma leggo di un bug del kernel... Ci capite qualcosa di più? Mi aiutate a risolvere? Grazie!
