I played around with this onlinescreensaver now. But I cannot get it working properly on my Kindle PW2. I have the bad 5.8.9.2 firmware and jailbreaked it via serial hack. This seems to work. I can install packages and so on.

Also the downloading and setting the picture works. But only if the Kindle is on. It seems the RTC cannot wakeup the kindle from suspend mode.

I made some experiments with the wait_for function. It can set the timer in /sys/class/rtc/rtc0/wakealarm and can reread the value. If I set the wait value to something so short that the device does not go to sleep, it correctly returns after the desired time. If I short press the power button to suspend the device after letting wait_for set the alarm it never returns until I power on the device.

Any ideas?

BTW. is there any way to set the screensaver timeout (maybe with the installed screensaver hack) or suspend/screensave the device via script.
