Autloading after laptop lid close not working

[SamuelBorn]

** My report

I am using my MX Master 3s (bluetooth connected, not thunderbolt) on my Dell XPS 15 7590.

The autoload works fine if I connect to the mouse while the laptop is running.

But when I close the lid and reopen+unlock the laptop, the remaps do not work anymore.

Turning off and on again bluetooth fixes the problem, is annoying though.

System Information and logs

1. input-remapper-control --version

input-remapper 2.0.1  https://github.com/sezanzeb/input-remapper
python-evdev 1.6.1

2. which linux distro (ubuntu 20.04, manjaro, etc.) fedora 39
3. which desktop environment (gnome, plasma, xfce4, etc.) gnome
4. sudo ls -l /proc/1/exe to check if you are using systemd lrwxrwxrwx. 1 root root 0 Dec 12 15:42 /proc/1/exe -> /usr/lib/systemd/systemd
5. cat ~/.config/input-remapper-2/config.json to see if the "autoload" config is written correctly

{
    "version": "2.0.1",
    "autoload": {
        "Logitech MX Master 3S": "Remap Mouse To Switch Workspaces"
    }
}

6. systemctl status input-remapper -n 50 the service has to be running

Testing the setup

1. input-remapper-control --command hello

Connected to the service
Daemon answered with "hello"
Done

3. sudo pkill -f input-remapper-service && sudo input-remapper-service -d & sleep 2 && input-remapper-control --command autoload, are your keys mapped now? yes
4. (while the previous command is still running) sudo evtest and search for a device suffixed by "mapped". Select it, does it report any events? Share the output. evtest not installed, sorry 7. sudo udevadm control --log-priority=debug && sudo udevadm control --reload-rules && journalctl -f | grep input-remapper, now plug in the device that should autoload

Same issue here using MX Master 3s on a Lenovo Flex but it tends to happen when the laptop is left unattended for a while. Not sure if it's related to the laptop going into some "sleep" state (don´t think so as I have configured it not to but the laptop's screen still goes dark) or the mouse going to sleep.

I can recover from the issue by executing the following command: systemctl restart input-remapper.service && input-remapper-control --command autoload

Same here with the MX Master 3 connected via Bluetooth. Service says:

input-remapper-service[17283]: ERROR: fd broke, was the device unplugged?
input-remapper-service[17283]: read loop for /dev/input/event13 stopped

Version:

python-evdev 1.4.0

Using Ubuntu 22.04 LTS.

I can recover from the issue by executing the following command: systemctl restart input-remapper.service && input-remapper-control --command autoload

For me just input-remapper-control --command autoload works too

Adding a quote of my comment on a possibly related issue as it might help with yours.

This is definitely not the Right Way (tm) to do this, but it works for my use case with a single bluetooth device being remapped and input-remapper sometimes failing on reconnect. If you have multiple devices being remapped, this will cause an interruption whenever a device disconnects. Also, it's quite hacky as I didn't spend a lot of time learning the codebase ¯\_(ツ)_/¯

I updated inputremapper/injection/event_reader.py to send stop_all and autoload commands to the daemon upon device disconnect. Here's the diff with added lines identified with +'s, surrounding lines (without "+") are provided for context:

# Added lines for inputremapper/injection/event_reader.py


# ---------------- import daemon methods ----------------
from inputremapper.input_event import InputEvent
from inputremapper.logger import logger

+# Load daemon methods to send commands upon device disconnect
+import inputremapper.daemon as ir_daemon
+

class Context(Protocol):


# ---------------- send `stop_all` and `autoload` to daemon ----------------
                loop.remove_reader(self._source.fileno())
                logger.debug("read loop stopped")
+                # Connect to daemon and send "stop_all" and "autoload" commands
+                daemon = ir_daemon.Daemon.connect()
+                await daemon.send_stop_all()
+                await daemon.send_autoload()
                return

            events_ready.clear()

Modified event_reader.py attached, had to rename to event_reader.py.txt because GH restricts attachment file types.
