investigate behavior when suspending or hibernating

[sezanzeb]

See https://github.com/sezanzeb/input-remapper/pull/219#issuecomment-988001940,

I think someone mentioned in a blog or something that suspend or whatever doesn't work with input-remapper

• [ ] Does a running injection stop? If yes, do the uinputs disapper? Are errors logged? Anything funny in debug logs?
• [ ] https://github.com/tmclane/jingpad/blob/main/99_jingpad_wakeup would key-mapper-control --command autoload without a config dir suffice?

I'm not facing any issues when suspending

[sezanzeb]

I'm not getting hibernate to work on my pc, someone else has to test it

[JProffitt71]

I am experiencing this issue on a S76 Meerkat with Pop!_OS 22.04 LTS installed. Where may I find the kind of logs you'd be interested in?

I also tried adding this file to my /usr/lib/systemd/system-sleep dir, but while it runs, it does not fix the issue:

#!/bin/sh

case "$1" in
    suspend|hibernate)
        /usr/bin/input-remapper-control --command stop-all
    ;;
    resume|thaw)
        /usr/bin/input-remapper-control --command autoload
    ;;
esac

exit 0

If I then manually run the command in a terminal after waking from sleep, it works just fine. I've tried adding a sleep in there before the command runs with values from 1 to 30 but that didn't work either, so it seems that there is something different about executing the script in the systemd context and executing it as a user.

[sezanzeb]

Try adding timeouts before calling input-remapper-control

As far as I remember this is controlled by the udev rule: https://github.com/sezanzeb/input-remapper/blob/main/data/99-input-remapper.rules. The file contains some information on how to debug udev.

systemctl status input-remapper might contain some useful information

Some logs can also be found in journalctl -b | grep input-remapper

I have to (re)Apply the preset after resuming from sleep, Fedora 39.

currently resorting to this method.

I also have to stop-injection and re-apply after suspension/standby, on Ubuntu.

EDIT: seems to be fixed; autoload wasn't enabled after the device was renamed by switching from USB interface to Bluetooth interface.

$ journalctl -b | grep input-remapper | tail -n30       # after resume from suspend/standby (no hibernation)

Issue is on the MX Anywhere 2S mouse, used via Bluetooth (because, somehow, the usb dongle isn't recognized anymore and had no time to figure out a fix).
