Standalone tool that turns the button on the Lamy Pen into an eraser on the reMarkable.
Also confirmed to work with these other styli:
- Samsung S6 S Pen
- Wacom One Pen CP91300B2Z
As an alternative, consider using this. (If you're already using ddvk-hacks, I'd defintely reccomend this route. This tool is for people who are looking for a less invasive option, and prefer the unaltered look of the reMarkable interface.)
The tool will definitely break when the reMarkable updates. When that happens, just reinstall!

Further customization can be done by adding arguments to ExecStart line of the LamyEraser.service file. This can be opened with nano /lib/systemd/system/LamyEraser.service.
The supported arguments are:
--press Press and hold to erase, release to use as a normal pen. This is the default behavior.
--toggle Press the button to erase, press the button again to swtich back to a normal pen.
--double-press undo Double click the button to undo. This is the default behavior.
--double-press redo Double click the button to redo.
--left-handed Use this option if you are using left handed mode.
For example, this line would use the toggle mode and redo on a double click:
ExecStart=RemarkableLamyEraser --toggle --double-press redo
To apply your config, run these commands:
systemctl stop LamyEraser.service
systemctl daemon-reload
systemctl start LamyEraser.serviceThe V2 branch of this project offers a ton of customization options, such as being able to select other tools, and configure exactly how you'd like to trigger erasing, undoing, among other things. It also knows what orientation your document is in, meaning that it works for portrait and landscape documents, regardless of your handedness. If you'd like to give it a try, uninstall this version, and reinstall from the V2 branch.
However, all this customization comes at a slight cost. The way that I've implemented the extra customization also means that basic actions of erasing and undoing aren't quite as "snappy" as version 1. Keep in mind that V2 is still in beta, and some things might not be as reliable.
It also (mostly) works with the RM1!
When you press the button on the Lamy Pen, an input event with code BTN_TOOL_RUBBER is sent into dev/input/event1. Essentially, this tricks the reMarkable into thinking you are using the eraser side of the Marker Plus.

sudo sh codex-x86_64-cortexa9hf-neon-rm10x-toolchain-3.1.15.sh) - source the printed environment file (e.g.
source /opt/codex/rm11x/3.1.15/environment-setup-cortexa7hf-neon-remarkable-linux-gnueabi) - compile
