Customizations for reMarkable Paper Tablet

reMarkable

Customizations for reMarkable and reMarkable 2 Paper Tablet. Script tested without problem on version 2.0.x, 2.1.x and 2.11.x

With 2.11.x image files are read only during startup, they are not hot loaded from the filesystem anymore, so to actually see the next image you need to restart the reMarkable. This means that even suspend image cannot be changed on the fly anymore, but you need to restart to see the new suspend image. I will explore the possibility to reload the interface in memory, but only if I can find a way to do it during sleep time and not when the user is actively using the device.

Automatically change your poweroff and suspend screens every 5 minutes

Manual installation

• Connect to your reMarkable via ssh and copy this repo into a temp folder i.e. /home/root/temp/reMarkable-1.0.1

• From the temp folder, create dedicated folders for your scripts and images

cd /home/root/temp/reMarkable-1.0.1
mkdir -p /usr/share/remarkable/scripts
mkdir -p /home/root/customization/images/poweroff
mkdir -p /home/root/customization/images/suspended

• Copy the script into the correct folder and set it executable

cp scripts/random-screens/set-random-screens.sh /usr/share/remarkable/scripts/
chmod +x /usr/share/remarkable/scripts/set-random-screens.sh

• Copy some images under dedicated folders

cp images/poweroff/* /home/root/customization/images/poweroff
cp images/suspended/* /home/root/customization/images/suspended

Name of the files is not important: every image in the folder will be elegible to be selected randomly by the script. You can find very good example in this repo. Note: I found them on Facebook but I can't remember the author anymore, I'm sorry. If you find him/her please PR this repo.

• Copy service and timer in the correct folder

cp scripts/random-screens/random-screens.service /usr/lib/systemd/user/random-screens.service
cp scripts/random-screens/random-screens.timer /usr/lib/systemd/user/random-screens.timer

• Save original images

cp /usr/share/remarkable/poweroff.png /usr/share/remarkable/poweroff.original.png
cp /usr/share/remarkable/suspended.png /usr/share/remarkable/suspended.original.png

You can now delete your temp folder.

• Enable service and timer

systemctl enable /usr/lib/systemd/user/random-screens.timer
systemctl enable /usr/lib/systemd/user/random-screens.service

• Restart your reMarkable

• You should now see one of your custom suspend and poweroff image in place. To do some troubleshooting, you can use these commands:

$ systemctl list-timers

Changing the timer

You can change the frequency of the refresh modifying the value OnUnitActiveSec inside the file /usr/lib/systemd/user/random-screens.timer and then restarting your reMarkable.
