Refresh screensaver?

peterson · 03-14-2014, 05:33 AM

I am looking for a way to refresh the active screensaver. I am running the weather-display to retrieve screensaver images, and would like the updated screensaver to be shown.

In theory this works by doing

Code:

lipc-send-event com.lab126.powerd.debug dbg_power_button_pressed

twice (once to turn it on, once to turn it back off). However in my particular case I have a passcode set, so when turning it on it only overlays the passcode input dialog, and when turning it back off it just removes the overlay without refreshing the screensaver.

So I am looking for a way to force a screensaver update. Is there some process that could be killed, triggered, ...? Alternatively, I could temporarily unset the passcode, however I do not know how (see also this other thread).

Might be a (near) lost cause if the device is asleep at the time, for obvious reasons.

If it isn't, it might be doable the "right" way, but nothing springs to mind (besides the hackish: overwrite the file and refresh/show it w/ eips).

Well, in this case the weather image won't be updated either :-)

Well, better than nothing. Thanks for the pointer to eips, I was not aware of this app. Using it works perfect. Of course it would be nicer if I could ask the framework to re-paint, but this should be sufficient.
