Ich habe einen AOC e2239Fwt Touch-Monitor (technische Daten siehe http://www.aoc-europe.com/no_cache/en/monitors.html?useCacheHash=1&showUid=2 ) mit Quanta Touch Sensor. Mit Ubuntu 10.10 hat er nur nach aufwändiger Einrichtung funktioniert, bis Ubuntu 11.04 wurden aber gut funktionsfähige Treiber in den Kernel aufgenommen und der XServer konnte mit dem Treiber via evdev umgehen. In Oneiric (11.10) Beta funktioniert der Touchscreen nicht mehr. Kann mir bitte jemand helfen, den Grund für diesen Fehler zu lokalisieren?

1. Wenn ich den PC mit angeschlossenem Touchscreen starte oder den Touchscreen im laufenden Betrieb anschließe, gibt das keine Probleme. Ausgabe von dmesg nach Anschließen:

2. Wenn ich den Touchscreen abstecke friert die Gnome-Shell ein, die Maus lässt sich noch bewegen, aber GUI-Anwendungen reagieren nicht mehr auf Input, Abhilfe schafft nur der Wechsel in eine tty und Beenden von z.B. gnome-session. dmesg Output:

Braucht ihr noch weitere logs? Oder andere Informationen?

EDIT: /etc/X11/xorg.conf existiert unter Oneiric nicht (mehr). wo finde ich vergleichbare Konfigurationen?

zeigt lsinput zu wenige ev bits an?
