**Testing the setup**

1. `input-remapper-control --command hello`

Connected to the service Daemon answered with "hello" Done

2. `sudo pkill -f input-remapper-service && sudo input-remapper-service -d & sleep 2 && input-remapper-control --command autoload`, are your keys mapped now? `No, it fails to remap it 2/3 times, see logs` [input-remapper.log](https://github.com/sezanzeb/input-remapper/files/13501363/input-remapper.log)
3. (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.

it has two devices: /dev/input/event20: input-remapper mouse /dev/input/event21: input-remapper ProtoArc EM03 Mouse forwarded

When remapper fails to autoload, 20 reports nothing. When it succeeds, it reports remapped input like

Event: time 1701266889.483849, -------------- SYN_REPORT ------------ Event: time 1701266889.633832, type 1 (EV_KEY), code 272 (BTN_LEFT), value 0 Event: time 1701266889.633832, -------------- SYN_REPORT ------------ Event: time 1701266893.047303, type 1 (EV_KEY), code 274 (BTN_MIDDLE), value 1

4. `sudo udevadm control --log-priority=debug && sudo udevadm control --reload-rules && journalctl -f | grep input-remapper`, now plug in the device that should autoload: 15:11:30 failed to autoload, 15:11:46 succeeded [udevadm.log](https://github.com/sezanzeb/input-remapper/files/13501450/udevadm.log)

## Notes

It suddenly stopped working, and I can't find why

the systemd service reports in the same time

Nov 29 15:49:40 slim-click input-remapper-service[108770]: Request to autoload for "ProtoArc EM03 Mouse" Nov 29 15:49:40 slim-click input-remapper-service[108770]: ERROR: Request to autoload "ProtoArc EM03 Mouse" before a user told the service about their session using set_config_dir



*update*: which is solved by running and adding /usr/share/input-remapper/input-remapper-autoload.desktop to autoload. But still, `FileNotFoundError: [Errno 2] No such file or directory: '/dev/input/event21'` is presented in the service logs
christopherseaman commented 7 months ago

Having a similar issue here. Bluetooth device reconnecting sometimes fails to load with a similar FileNotFoundError: [Errno 2] No such file or directory: '/dev/input/eventX error.

@Felixoid - It sounds like adding input-remapper-autoload.desktop to autoload fixed the issue for you, but the error remains. Does this mean you're setting input-remapper-autoload.desktop to run on GUI login and disconnect/reconnect cycles now work for you? I tried adding input-remapper-autoload.desktop to ~/.config/lxsession/LXDE-pi/autostart, but still have the issue upon bluetooth reconnect.

My workaround has been to define an action on my phone to send input-remapper-control --command stop-all && input-remapper-control --command autoload via ssh. (Shout out to ServerCat for making that a single tap).

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.
