Configuration

Change SSH password

The default IP and SSH password of the Remarkable tablet can be found in the settings menu.
Navigate to it as follows: Menu > Settings > General > Help > About > Copyrights and licenses > General information > GPLv3 Compliance.

The password is stored in /home/root/.config/remarkable/xochitl.conf.

[General]
DeveloperPassword=remarkable

Older versions

Running Software release 2.x.

The password is stored in /etc/remarkable.conf.

Fix SSH lag

Execute the following command on the device:

$ iw wlan0 set power_save off

Updating timezone

The Remarkable's timezone is set to UTC.
Due to unknown reasons, the reMarkable interface does not expose a visible clock to the user. remarkable-hacks does expose a clock to the user, hence why we need to set the correct timezone.

$ timedatectl set-timezone "Europe/Paris"

To see what timezones are available look at the contents of /usr/share/zoneinfo.

Additional functionality

Software release 2.x

remarkable-hacks adds a literal metric ton of additional features to the Remarkable. Follow the installation instructions in the project's README.

Software release 3.x

rm-hacks seems to be the spiritual successor to remarkable-hacks on software 3.x+.
