What's the benefit or purpose of the interception driver support?

[riotrah]

I imagine it's a matter of "If I need to ask I don't need it" or something, but I cannot tell what the interception driver offers over kanata's default windows implementation. But it might be useful - I just can't tell

The main thing is that the llhook mechanism is subject to permission issues where you can't use it with administrator priveleged applications unless kanata is also run with administrator privileges. Last I remember, it can't be made to work in the login screen even if kanata is made to run as a service. It also won't work for VM applications like VMware.

The interception driver solves the above issues. It also fixes some issues with specific windows keycodes, but then introduces some of its own unique bugs...

The Linux mechanism is much better than either of Windows' options in my opinion haha.

Huh! Thanks!

What are some of the cons then?

The most egregious one is:
oblitum/Interception#25

The driver is not open source, which to be fair to the creator, it's their project and they can do what they want. The reality of it though is that this issue has been around for years and since it's not open source, us other open source users of the driver can't go contribute a fix. It's a bad user experience.

There are also a few keys that are currently not handled correctly, like Pause and some international keys.

For future readers: it's possible to self-sign kanata and add UIAccess (see the config.adoc) to make it work in admin apps without running itself with admin. Other limitations unfortunately remain

The interception bug oblitum/Interception#25 sounds scary, but I didn't see it happen under normal work conditions, even though I can force it by simply unplug/replug my mouse 4 times.

• But Hybernation does not count toward that limit (I'm using a docking station)
• I used a Buetooth keyboard, wich lowered the likelyhood of usb plugging events
