Joggler Screen Saver

Looking for an easy way to turn a Joggler (unmodified) in to a screen saver. All I want is SSH to be able to copy pictures to it.

IE: such that when it boots up it goes directly to a screen saver...no menu nothing else...

This is a little project for gifting Jogglers.

Thank you Gary.

Yes looking to utilize the Joggler only for this endeavor. 1Gb eMMC for the OS with a minimal or no Linux GUI and the Joggler tabletop will access a share on a Windows 10 desktop which is on all of the time (resting though).

Might start with Buzz's minimum server build and go from there...

I did this for a video demo at OggCamp last year... I might still have the image around somewhere, though it may only have been set up for MP4s.

Thank you Andy.

Yes; just want to have a 24/7 screen saver on the Joggler and do a cron job to shut off the screen after hours for mom (~90) here.

Pictures will be either a share or usb stick and access to update will be remote SSH.

Hi Pete,
Just pulled my old Joggler out of the garage to do exactly this. Just wanted to put it on my desk at work cycling family photos. I was going to put up with the sunset OS which can have the start time to 15 secs so comes on near instantly on boot but I can't find a way to slow the transition of the slides down.

I found this 'http://karuppuswamy.com/wordpress/2010/ ... -on-linux/' but I'm not great with Linux and haven't found a slim build yet for the Joggler.

Please post anything you find that works as I'd be interested in trying.

Thank you Smiley.

Yes will give this one a try to see if it works on the embedded 1Gb eMMC version of Linux. Might be able to install the lite server and add just what I need for this.

Well trying your way Smiley with a tweak.

Found an old Joggler which was apart and sort of modded with an extra USB port and trashed traces for a ZIF connector. Reinstalled the wireless stick and reglued two wires for wireless stuff.

Steps:
1 - writing a MAC address first redoing boot bios to Seabios, boot with dos stick and writing MAC address
2 - rewriting the O2 EFI bios on it
3 - starting maybe with Squeezeplayer OS first. Then removing start up of Squeezeplayer OS

...to be continued.

This one has one of those screens that is almost white on first boot.

1 - wrote the Squeezeplayer OS to the eMMC
2 - booted up with Buzz's first Ubuntu build from a few years back
3 - updated and installed ssh server
4 - writing seabios to rom....
a - ssh'd to Joggler
b - plugged in dos boot stick
c - mapped usb stick
mount -t vfat -o rw,users /dev/ubb1 /mnt/myusb
d - wrote seabios rom to efi rom
root@joggler:/mnt/myusb# dd if=coreboot.rom of=/dev/fh count=1 bs=1024k
1+0 records in
1+0 records out
1048576 bytes (1.0 MB) copied, 8.18463 s, 128 kB/s
e - reboot
f - wrote mac address
pg8168 /nodeid 000001000002
g - reboot and hit f7 to write O2 rom back
h - upgrade back to O2 rom is using default name of upgrade.rom
i - back to efi bios
5 - default boot should not be at Squeezeplayer OS which it is.

Tried to create a small xwindows image to fit on Gb emmc. None was small enought.

Installed Squeezeplayer and image screensaver. Well then installed Squeezeserver on main computer in house. Works great this way.

Smallest here before desktop is 965Mb on a 1Gb eMMC.

Thinking you can get by installing Squeezeplayer on the 2 Gb emmc (old OS though) and then add a small desktop to it.

That said had my squeezeplayer / screen saver / O2 Joggler / 1Gb emmc working well for two days and then no boot.

Gonna try a low level format and repair of the emmc using an old DOS program called hddguru. I have used this program to fix USB and SD cards but never have tried it on an eMMC. That said will install it on my USB DOS boot stick that I use to upgrade / modify ROM. See what happens today.

Well just noticed that the HDDGURU program only runs in windows. Looking for an older one that runs in dos. I have one here someplace...

To do this will need to write the seabios boot to it again which I can do easy enough; then boot with USB DOS stick.

So as I was having problems with the Joggler being used as a screen saver redid the eMMC. It seems to boot faster and it cold boots to Squeezeplayer every time.

I resized the second partition making it smaller by some 30Mb and deleted the Fat16 partition and wrote it as a Fat32 partition giving it the boot and lba stuff.

Copied all of the contents back to it and it seems to be doing well.
