I will do some more debugging to check what exactly goes wrong, but I am leaving for OLS tomorrow. BTW I don't know if you recall - I reported previously that the keypresses are lost only if I try to hit the key very soon after the keyboard gets suspended. If I wait for 2 seconds (looks like exact value), then no keypressess are lost and the keyboard wakes up properly. When I change the autosuspend values of all devices in system from 2 (default) to 5, the value described in the previous paragraph (i.e. the minimum time for which the keyboard must be suspended before it could be woken up flawlessly) is still 2 seconds. -- Jiri Kosina ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
