Karabiner-elements: Unload karabiner_grabber when Quitting Karabiner

[iandol]

Hi, when we quit Karabiner, karabiner_grabber remains loaded. This breaks the use of keyboard logging in MATLAB, so I have to both quit Karabiner, then sudo launchctl unload the karabiner_grabber.plist.

Would it be possible if Karabiner could load/unload karabiner_grabber when starting and stopping?

Thanks for such an amazing utility.

It seems there is a new daemon karabiner_observer and this also interferes with MATLAB lowlevel keyboard access too, so I need to unload both manually, here are aliased commands to start and stop karabiner for the moment:

alias karabinerLoad='launchctl load /Library/LaunchAgents/org.pqrs.karabiner.karabiner_console_user_server.plist; \
sudo launchctl load /Library/LaunchDaemons/org.pqrs.karabiner.karabiner_grabber.plist; \
sudo launchctl load /Library/LaunchDaemons/org.pqrs.karabiner.karabiner_observer.plist;'
alias karabinerUnload='launchctl unload /Library/LaunchAgents/org.pqrs.karabiner.karabiner_console_user_server.plist; \
sudo launchctl unload /Library/LaunchDaemons/org.pqrs.karabiner.karabiner_grabber.plist; \
sudo launchctl unload /Library/LaunchDaemons/org.pqrs.karabiner.karabiner_observer.plist; \
sudo killall karabiner_grabber; \
sudo killall karabiner_console_user_server; \
sudo killall Karabiner-Menu; \
sudo killall Karabiner-Elements'

There is still a significant incompatibility between Karabiner and MATLAB toolboxes used for neuroscience and psychology research...

This is getting worse for me, now I need to also unload the kext — but often the kext fails to unload even if karabiner and all its daemons and services are fully quit...

alias karabinerUnload='launchctl unload -F /Library/LaunchAgents/org.pqrs.karabiner.karabiner_console_user_server.plist; \
    sudo launchctl unload -F /Library/LaunchDaemons/org.pqrs.karabiner.karabiner_grabber.plist; \
    sudo launchctl unload -F /Library/LaunchDaemons/org.pqrs.karabiner.karabiner_observer.plist; \
    sudo killall karabiner_observer; \
    sudo killall karabiner_grabber; \
    sudo killall karabiner_console_user_server; \
    sudo killall Karabiner-Menu; \
    sudo killall Karabiner-Elements; \
    sudo kextunload /Library/Application\ Support/org.pqrs/Karabiner-VirtualHIDDevice/Extensions/org.pqrs.driver.Karabiner.VirtualHIDDevice.v060800.kext;'

This is still a problem...

Well.........same issue here.

Hi, in recent karabiner-elements, deselecting the keyboard in the preferences:

https://pqrs.org/osx/karabiner/document.html#configuration-devices

...allows the HID keyboard driver to work without issue (MATLAB 2018b), so I think this is the best solution as we just create a profile with keyboard disabled and toggle profile as needed (no need to load/unload kexts manually).

Thanks for your documentation!

I also encountered a similar issue, as setledsmac does not work while the Karabiner's Kext is driving the given keyboard. Using your proposed profile-based approach (temporarily switching to an empty profile via karabiner_cli), everything works flawlessly 🤗

Cheers!
