Ich habe kürzlich Ubuntu 12.04 auf 12.10 aktualisiert, nur um herauszufinden, dass es keine Verbindung zu einem Netzwerk herstellt, weder kabelgebunden noch kabellos, und die Grafik ist ebenfalls durcheinander wie bei einer niedrigen Bildschirmauflösung.
Für den 12.04 lief mein System einwandfrei. Ich weiß nicht, warum das Upgrade es so schlimm durcheinander gebracht hat. Die Neuinstallation des Betriebssystems ist ein Problem, da ich viele Entwicklungsumgebungen eingerichtet habe, die ich mir nicht leisten kann, es erneut einzurichten.
