Online screensaver extension

[andraz]

For some reason, on random occasion (could be after 2 days or after a week) it stops working. And when I wake up the kindle pressing the button I see there's no airplane mode icon at the top-right corner. Internet won't work until I enable the airplane mode again. Why this happens, I have no idea yet. Has any of you noticed this?

Hi everyone and thank you for all the effort you spent. Unfortunately I need some help to get the auto update working.
So to make it short: My PW1 running at 5.6.1.1 is jailbraked and manually updating the screensaver png is working properly. But if I activate auto update the script is trying to set the .../rtc1/wakealarm without success - as far as I understand...
To have a look in the log:

If I try to set the wakealarm manually

echo 1659835803 > sys/class/rtc/rtc1/wakealarm

and do a

cat sys/class/rtc/rtc1/wakealarm

, it is empty. Also

cat /proc/driver/rtc

displays no alarm set.

What additionally makes me wondering is the printed schedule

00:00-06:00=480 06:00-24:00=10 24:0-30:0=480 30:0-48:0=10

. I did not set the last part of the schedule in config.sh, but

00:00-06:00=480 06:00-24:00=10

. Don't know why this is printed in the log.

Thank you in advance for any hint.
Please ask, if I missed some important information.

Thanks to these two posts bellow, I could have onlinescreensaver working on a KT2 (basic 2014) with FW 5.10.3 :



Thanks a lot Peterson for the onlinscreensaver scripts, mironov for finding how to wake the kindle from sleep and jonnydeath for the path tricks!

set_rtc_wakeup()
{
	lipc-set-prop -i com.lab126.powerd rtcWakeup $1 2>&1
	logger "rtcWakeup has been set to $1"
}

##############################################################################
# sets an RTC alarm
# arguments: $1 - time in seconds from now

wait_for () {
	ENDWAIT=$(( $(currentTime) + $1 ))
	REMAININGWAITTIME=$(( $ENDWAIT - $(currentTime) ))
	logger "Starting to wait for timeout to expire: $1"

	# wait for timeout to expire
	while [ $REMAININGWAITTIME -gt 0 ]; do
		EVENT=$(lipc-wait-event -s $1 com.lab126.powerd readyToSuspend,wakeupFromSuspend,resuming)
		REMAININGWAITTIME=$(( $ENDWAIT - $(currentTime) ))
		logger "Received event: $EVENT"

		case "$EVENT" in
			readyToSuspend*)
				set_rtc_wakeup $REMAININGWAITTIME
			;;
			wakeupFromSuspend*|resuming*)
				logger "Finishing the wait"
				break
			;;
			*)
				logger "Ignored event: $EVENT"
			;;
		esac
	done

	logger "Wait finished"
}

Hope it helps someone

I'm trying to get this working on my PW2 on 5.11.1.1 but unfortunately screen saver is still the default linkss one

I had to edit the bash files paths for it to work, and it runs now with this output:

[root@kindle bin]# /mnt/us/extensions/onlinescreensaver/bin/scheduler.sh &
[root@kindle bin]# Sat Dec 10 11:45:03 MST 2022: Full two day schedule: 0:0-24:00=15 24:0-48:00=15

Despite the mv error, I have verified the script is actually getting the png I told it to and saved as bg_medium_ss00.png . But bg_ss00.png is what gets displayed (the default linkss image)

Surely Im doing something wrong here. Any help would be greatly appreciated. Thank you

Worked on this quite a bit today and made progress but not quite there yet. I set in config to save as bg_ss00.png instead. Another issue I ran into (which was my fault of course) was that my png was not 8 bit. That gave error: eips: paint_image> cannot open "/mnt/us/linkss/screensavers//bg_medium_ss00.png":8bit only

I have it working reliably without issue when connected to USBnetwork and run manually (although gives the error com.lab126.powerd failed to set value for property deferSuspend (0x100 lipcPropErrInvalidState) ) but once I disconnect USB, it will update one more time then it stops updating

If WIFI is not disabled when Kindle is awake, it gets suspended by the system when it falls asleep. In this case, the command "lipc-get-prop com.lab126.cmd wirelessEnable" will still return 1 even though there is no connection established (no response to ping). It is possible to overcome this by simulating a press of the physical button and waking the Kindle before the script execution (this has been implemented in Stefan's version). But doing that the backlight will flash every time the screen gets updated.

Amazing, thank you. I've been losing my mind tryingt to figure this out.

Just registered to throw my hat in the ring as someone interested in this issue.
I had this working for a period of time pulling an image from my local network.
It seems to have just died and I can't see any changes between my repository version and what is present on the kindle.

I have noticed that config.sh and utils.sh sometimes change in to some other text file.
I have no idea what is doing that but the scripts are wiped out and replaced with something else (looks like a readme or something).
I haven't had the foresight to capture a sample of that, but I will in the future.
My guess is that change is associated with the FS going RO for a period.
Remounting seems to fix the issue with the RO FS.

I believe I have tried all the things mentioned up until this point and I'm just stuck now.
Real shame because I had it working for a good long stretch yesterday.
I can see when I mount the device that it is downloading the latest images.
It just seems like it won't actually refresh the screensaver anymore.
Any tips are appreciated, even if it is go back and try something that worked for someone else in the same situation.

Well I am glad its not just me. I have also been entirely unsuccessful in getting it to update the screen from sleep (updates no problem when connected to power). Ive also seen that issue where the files seems to become corrupted. I chalked it up to editing from USBMS and corrupting somehow but maybe theres more to it

I even went as far as to buy a K5 in addition to my PW2 (since they're so cheap) and unfortunately, same result, does not update from sleep state

Glad I'm not alone. Hopefully we can figure this out. Same issue for me, does not update screen from sleep (but does work just fine when connected to power). I even went as far as buying a K5 in addition to my PW2 (since they're so cheap) and unfortunately same result, does not update from sleep

I've also noticed that file corruption issue. I chalked it up to an issue with editing from USBMS but maybe theres more to it

[njnygaard]

Here's an example of the corruption that happens sometimes.
I'm really not sure what is replacing the files in onlinescreensaver (only) or what the file is.
It just looks like chunks of the fonts readme?
My gut feeling is that this would be a conflict with another extension, but I didn't think I had any others installed.

I got mine to work!
I have the script update from mironov.
Then in config.sh:
SCHEDULE="00:00-06:00=15 06:00-22:00=15 22:00-24:00=15"
SCREENSAVERFILE=$SCREENSAVERFOLDER/bg_ss00.png
DISABLE_WIFI=1
RTC=0
TEST_DOMAIN="192.168.1.146" #Personal
IMAGE_URI="http://192.168.1.146/kindle/image.png" #Personal

I've set the airplane mode to off.
After making all the changes, I restart the kindle from the interface and let it boot and go to sleep by itself.
I woke up this morning and my image was updating.

Notably I think the most important thing is assuring that the image is 8bit Gray. 16bit absolutely crashed my unit. RGB images get stretched out. I've written the image creation software in go, stealing a lot of the code from https://github.com/fogleman/gg
I've had to take code out of that repo because it was written for only RGB contexts and I couldn't think of a way to make a clean PR for Gray. I'll be working on that when I get the functionality I want out of my weather station.

I hope something there works dan-
I'll keep watching the thread.

Has anyone managed to get it to work without turning off wifi? I've tried everything in the thread. But if I use the device and forget to turn wifi off, it will fail to update.

I'm running on PW5, while testing I've set it up to update every 30 minutes and worked well, however when I change to 120/240 minutes standard schedule it never wakes up.
I'm wondering if the system goes to a deep sleep and the watchdog is not coming up.
Ideally I wanted it to update once a day in the morning, that would give me the best results. But I'm having a hard time having it wake up.

Anyone running successful on a PW5 ?

There's likely to be differences in how the RTC works on the PW5 vs the older devices that this extension was written for. The developer hasn't updated it for the better part of a decade so this is something that you're going to have to debug + fix yourself.

I kept digging and found that the code on post Post 78 works. So I'm using it. So far it's fine. Will refine it more later after I confirm it runs for a few days.
