Ragazzi riprendo il topic per cercare una soluzione a un fastidioso problema..cioè il crash dell'interfaccia grafica e ritorno alla schermata di login.
sopra avevo scritto che capitava con il gioco amnesia...ebbene LO STESSO problema succede quando accedo alle impostazioni di un programma come vlc.
Per esempio apro VLC - poi su STRUMEMNTI - poi PREFERENZE - poi AUDIO e poi appena clicco su MODULO di USCITA ecco che la schermata diventa nera e ritorno alla schermata di login.
Vi posto il file /var/log/syslog non ci capisco molto... se qualcuno può darmi una mano perchè succede con altri programmi e sinceramente non mi và di formattare e reinstallare ubuntu.


questo è quello che capita quando sono andato nelle impostazioni di VLC alle 22.16 (primi secondi)
