Hello Maemo Developers,



Maybe someone can help me - I bought a 770 second-hand recently and love it BUT it has one strange behaviour; it shuts itself down periodically - usually when it hasn't been used for a little while (~5-10 mins) whether the screen is exposed or covered.  I really want to be able to use the standby mode covering the screen and being able to quickly start again but at the moment I always have to reboot.

I don't think its a battery problem because I get hours of use out of it if I keep tapping away. ; Sometimes it stays on longer, although I am not sure why...



Anyway - anyone else seen this? ;

Anyone know of a way to trap messages that might explain why its doing this? ;

Is there an equivalent to /proc/bootreason that explains why it previously shut down? ;

I used dbus-monitor (see below) but don't think I'm getting much useful information - what do you think?

Its running OS2006 49-2.




Any thoughts appreciated!!



Thanks



John



----------

output of a dbus-monitor session over ssh at the end of which the 770 had shut itself down. ; I closed and opened the screen to see what messages were sent. i have set wireless to stay on even if screen covered.




the "save_unsaved_data_ind"; message looks ominous, obviously 770 thinks something bad is about to happen....

unfortunately dbus-monitor doesn't output timing of messages...

    Hi John. Why don't you just reflash it all and start clean?

Salut.
Sebas.

AFAIK this is normal, it's sent always when screen is
blanked.
