reMarkable Software Version Compatibility

• ✅ All software versions

Installation

To start, enable developer mode and gain ssh access to your tablet. The install instructions assume you are sshing over USB where the tablet will show up at 10.11.99.1. If you are sshing wirelessly, substitute the correct IP address.

Warning

Enabling developer mode will wipe your tablet.

Install

1. Download install-reLuminate.sh

2. Copy install-reLuminate.sh to reMarkable tablet

   scp install-reLuminate.sh root@10.11.99.1:~
   

3. ssh to reMarkable tablet

   ssh root@10.11.99.1
   

4. Install reLuminate

   bash install-reLuminate.sh install
   

Remove

1. Uninstall reLuminate

   bash install-reLuminate.sh remove
   

Usage

To enable reLuminate service (done automatically on install), run:

systemctl enable reLuminate --now

To disable reLuminate service, run:

systemctl disable reLuminate --now

How Does It Work?

During boot, the service will enable the linear_mapping mode and set the screen brightness to max. Now the brightness slider will have access to higher brightness levels.

echo yes > /sys/class/backlight/rm_frontlight/linear_mapping
cat /sys/class/backlight/rm_frontlight/max_brightness > /sys/class/backlight/rm_frontlight/brightness
