Das Toshiba schickt leider für viele ACPI Tasten immer zwei Events kurz hintereinander. Besonders doof ist das freilich beim Suspend, let sich das dumme Ding doch sofort nach dem Einschlafen erneut zu einem kleinen Nickerchen nieder.
Ich entprelle darum die Tasten auf etwas ruppige Art und weise. Jeder Event wird in eine Datei geschrieben, zusammen mit einem Timestamp. Tritt dasselbe Event innerhalb von 400ms erneut auf wird es abgelent. Fürs Suspend reicht das alleine freilich nicht aus, darum wird beim ersten Event eine Marke in die Datei geschrieben, und erst beim zweiten legt sich das Notebook tatsächlich schlafen. Diese Methode scheint zwar eleganter zu sein, würde aber erfordern das ich nachsehe welche Tasten genau zum prellen neigen, worauf ich keinen Nerv habe.
