⚠️ For reMarkable 2 users ⚠️: rMview should work out of the box with the stock firmware. If you use rm2fb there are known compatibilities issues that are being addressed.

The most efficient installation method is the semi-automatic one below, which requires a Python3 installation. If you are looking for a standalone executable, check the releases page for executable bundles. If there is no bundle for your operating system then follow the installation instructions below.

As a basic prerequisite you will need Python3 on your computer.

⚠️ Please make sure pip is pointing to the Python3 version if your system has Python2 as well. If not, use pip3 instead of pip in what follows.

⚠️ WARNING ⚠️: If you use Anaconda, please install the dependencies via conda (and not pip) then run pip install ..

The easiest installation method is by using pip, from the root folder of this repository:

   pip install .

(please note the command ends with a dot) which will install all required dependencies and install a new rmview command.

Then, from anywhere, you can execute rmview from the command line. The tool will ask for the connection parameters and then ask permission to install the VNC server on the tablet. Press Auto install to proceed.

If you plan to modify the source code, use pip install -e . so that when executing rmview you will be running your custom version.

Install the dependencies (PyQt5, Paramiko, Twisted) with pip or conda manually:

# install dependencies
pip install pyqt5 paramiko twisted
# build resources file
pyrcc5 -o src/rmview/resources.py resources.qrc

On the reMarkable itself you need to install rM-vnc-server by copying the relevant binary from the bin folder:

# For reMarkable 1
scp bin/rM1-vnc-server-standalone root@REMARKABLE_ADDRESS:rM-vnc-server-standalone

# For reMarkable 2
scp bin/rM2-vnc-server-standalone root@REMARKABLE_ADDRESS:rM-vnc-server-standalone

Then you can run the program with python -m rmview.

Suggested first use: after installing run rmview, insert when prompted the IP of your tablet and the password, as found in the Menu / Settings / Help / Copyright and Licences menu of the tablet. Then, optionally, select "Settings..." from the context menu (or the error dialog) to open the default configuration file which you can edit according to the documentation below.

More generally, you can invoke the program with

rmview [config]

the optional config parameter is the filename of a json configuration file. If the parameter is not found, the program will look for a rmview.json file in the current directory, or, if not found, for the path stored in the environment variable RMVIEW_CONF. If none are found, or if the configuration is underspecified, the tool is going to prompt for address/password.

The supported configuration settings are below. Look in file example.json for an example configuration. All the settings are optional.

Connection parameters are provided as a dictionary with the following keys (all optional):

The address parameter can be either:

• a single string, in which case the address is used for connection
• a list of strings, which will be presented at launch for selection

To establish a connection with the tablet, you can use any of the following:

• Leave auth_method, password and key unspecified: this will ask for a password
• Specify "auth_method": "key" to use a SSH key. In case an SSH key hasn't already been associated with the tablet, you can provide its path with the key setting.
• Provide a password in settings

If auth_method is password but no password is specified, then the tool will ask for the password on connection.

As a security measure, the keys used by known hosts are checked at each connection to prevent man-in-the-middle attacks. The first time you connect to the tablet, it will not be among the known hosts. In this situation rMview will present the option to add it to the known hosts, which should be done in a trusted network. Updates to the tablet's firmware modify the key used by it, so the next connection would see the mismatch between the old key and the new. Again rMview would prompt the user in this case with the option to update the key. This should be done in a trusted network. The host_key_policy parameter controls this behaviour:

• "ask" is the default behaviour and prompts the user with a choice when the host key is unknown or not matching.
• "ignore_new" ignores unknown keys but reports mismatches.
• "ignore_all" ignores both unknown and not matching keys. Use at your own risk.
• "auto_add" adds unknown keys without prompting but reports mismatches.

The old "insecure_auto_add_host": true parameter is deprecated and equivalent to "ignore_all".

In case your ~/.ssh/known_hosts file contains the relevant key associations, rMview should pick them up. If you use the "Add/Update" feature when prompted by rMview (for example after a tablet update) then ~/.ssh/known_hosts will be ignored from then on.

⚠️ Key format error: If you get an error when connect using a key, but the key seems ok when connecting manually with ssh, you probably need to convert the key to the PEM format (or re-generate it using the -m PEM option of ssh-keygen). See here for details.

• About dialog
• Pause stream of screen/pen
• Binary bundles for Window, Linux and MacOs (PyInstaller?)
• Add interaction for Lamy button? (1 331 1 down, 1 331 0 up)
• Remove dependency to Twisted in vnc branch

There are two versions of rMview, presenting the same interface but using different back-ends (thus requiring different setups on the reMarkable):

• The "VNC-based" version, in the vnc branch (default)
• The "reStreamer-like" version, in the ssh branch

In my tests, the VNC version is a clear winner. The ssh branch of this repo hosts the reStreamer-like version for those who prefer it, but it should be considered unmaintained.

The VNC server running on the tablet is developed by @pl-semiotics:

• rM-vnc-server

I took inspiration from the following projects:

• QtImageViewer
• remarkable_mouse
• reStream
• VNC client originally written by Chris Liechti
