Ubuntu 11.04 meldet sich zufällig während der Nutzung ab [closed]

Ich kann sehen, dass es bereits eine Frage gibt. Da mein Problem nicht ganz dasselbe ist, aber, soweit ich es verstehe, ziemlich ähnlich, stelle ich es auch.

Grundsätzlich in der Mitte meiner Nutzung, dh im Internet surfen oder eine zufällige Anwendung ausführen. Ubuntu schickt mich zum Anmeldefenster und ich muss mich neu anmelden. Ich weiß nicht, ob GDM neu startet oder etwas anderes. Dies ist ein Problem, mit dem ich selbst in der stabilen Version von Ubuntu konfrontiert bin.

Gibt es einen Fehler, den ich nicht kenne? Wie kann ich das debuggen?

Hier ist meine ~/.xsession_errorsDateiausgabe.

Ich habe vor kurzem ein Update für Gnome-Sessions bekommen. Ich hoffe das löst das Problem, allerdings kann ich erst nach ein paar Testtagen sicher sein ... Wird die Situation aktualisieren.

UPDATE: Nein, kein Fortschritt, ich habe das Update erhalten, aber das Problem bleibt bestehen. Aber es scheint viel seltener zu sein als früher. Ich verfolge diese Frage, da einige Leute mir vorgeschlagen haben, sie neu zu installieren, aber jetzt friert Unity nach einer Konfigurationsänderung von compiz ein

Das ist ein Fehler .

Das kann ein Absturz des Grafiktreibers sein. Was ist deine Grafikkarte? Verwenden Sie einen proprietären Treiber? Wenn ja, versuchen Sie es mit einer anderen Version oder entfernen Sie sie vollständig. Oder leider kann es viele andere Teile der Hardware sein. X-Server ist ein Koloss auf Lehmbeinen und am anfälligsten für Hardwarefehler. Überprüfen Sie den Speicher (memtest86), die Festplatte (fsck, smart) und die Temperaturen (lm-Sensoren). Versuchen Sie, alle unnötigen Hardware- und Softwarekomponenten auszuschalten. Ich hatte X-Server-Abstürze gesehen, als EiskalDC ++ zum Beispiel versuchte, eine 100-GB-Datei zu indizieren. Hast du Logs gelesen, dmesg? Irgendetwas Verdächtiges? PS Schalten Sie compiz aus. In Ubuntu ist es standardmäßig aktiviert.

Verwenden Sie Unity oder GNOME? Versuchen Sie es mit dem anderen. Wenn das nicht funktioniert, empfehle ich Try Xubuntu (um zu sehen, ob es GNOME ist). Wenn alles fehlschlägt, sichern Sie Ihre Home-Partition oder Ihren Home-Ordner, kopieren Sie / var / cache / apt in einen anderen Ordner und installieren Sie ihn erneut. Verwenden Sie die Pakete aus dem Cache, um Ihre Anwendungen erneut zu installieren.

Versuchen Sie (in einem Terminal, ohne SUDO):

unity --reset

Berühren Sie dann nicht mehr CCSM (Compiz-Einstellungen). Ich weiß nicht, ob dies in Ihrem Fall wirklich hilft, aber ich bin in der gleichen Situation und teste derzeit, ob die Abstürze immer noch auftreten.
