If you modify the capabilities after that happens, you need to call input-id again to get updated udev properties. There is no kernel facility to handle devices that change capabilities at runtime. We discussed this a short while ago (search for SYN_CONFIG) but it's ... tricky. Cheers, Peter

So for this to work reasonably either - all devices should have all capabilities by default - the capabilities should be detected based on the events actually available on the device And if my keyboard actually claimed to have relative axis because of some great firmware engineering on the manufacturer's part and I found how to remove them in hwdb it would not take effect either.

It is not the default keyboard behavior. Having another custom udev rule to mark the device as ID_INPUT_MOUSE is a fair requirement in this case I think. -- Dmitry

This keyboard only has buttons though. So it gets ID_INPUT_KEYBOARD for the keys, but no ID_INPUT_MOUSE. Google isn't overly forthcoming on "DELL Dell USB Entry Keyboard" but the few pictures I can find all point to a keyboard that doesn't have any physical mouse buttons at all. Does yours have buttons?

This is what evtest reports about my keyboard:
Select the device event number [0-12]: 2
Input driver version is 1.0.1
Input device ID: bus 0x3 vendor 0x413c product 0x2107 version 0x111
Input device name: "DELL Dell USB Entry Keyboard"
Supported events:
Event type 0 (EV_SYN)

just because it's not immediately apparent doesn't mean it's random.
We use ID_INPUT_* from udev to determine the device capabilities. In some
cases we override it when we have some information udev doesn't have. e.g.
we disable gestures on some touchpads known to be inaccurate for
multi-finger gestures. or on some devices we disable event codes because the
device doesn't actually have them. see my explanation here:
https://who-t.blogspot.com.au/2015/06/libinput-and-lack-of-device-types.html
the reason we do it this way is so that a) all of the stack can agree on a
device's device type and b) you can override many misdetections with a hwdb
entry or a custom udev rule rather than waiting for a new libinput release
that encodes the new magic.

That's actually libinputs fault. It marks devices with some random
capabilities and when the event does not match capability set it is
dropped.
Adding the capability with /etc/udev/rules.d/xxx-input.rules
ENV{ID_INPUT_KEYBOARD}=="1" ENV{ID_INPUT_MOUSE}="1"
resolves the problem. It must come very late in rules otherwise
something resets it back.
This is inefficient to enable by default because libinput must create
a second shadow X11 device for devices that generate both input and
keyboard events.
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DELL Dell USB Entry Keyboard id=8 [slave pointer (2)]
⎜ ↳ PixArt Dell MS116 USB Optical Mouseid=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboardid=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ DELL Dell USB Entry Keyboard id=10 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
Presumably it could infer the capabilities from the supported events
rather than hardcoding them in udev. Surely there are devices with
stub/broken features that do not actually generate events but that is
hopefully not the norm.
Anyway, this mapping is doable with hwdb provided the list of events is
updated to include the BTN_* events. It is quite isolated change to one
heade

Such keymap update just does not work as mouse button regardless of sending the BTN_* event. At least not in X11. So what is next? Thanks Michal

I am doing my job as a maintainer right now. The driver might have been beneficial 15 years ago, when we did not have better options, but I would rather not continue expanding it's use. The main problem with the driver is that the functionality it is not easily discoverable by end users. And once you plumb it through userspace to present users with options you might as well handle it all in userspace. > > If you want to move drivers/input into userspace I am not against it > but I am not willing to do that for you either.

Have you tried simply redefining keymap of your keyboard to emit BTN_RIGHT/BTN_MIDDLE? Both atkbd and HID keyboards support keymap updates from userspace/udev/hwdb and if there is a driver that does not support it I will take patches fixing that. Thanks. -- Dmitry

What is the status of this?
Do you reply to every patch to drivers/input that is not the the core
infrastructure that you would rather drop the driver because it can be
done is in userspace?
It sure can be done. Remove everything but the bus drivers and uinput
from drivers/input and the rest can be done in userspace.
The question is who does it?
Are you saying that you will implement the userspace equivalent?
If not then please do your job as maintainer and accept trivial patches
for perfectly working drivers we have now.
If you want to move drivers/input into userspace I am not against it
but I am not willing to do that for you either.

Any touchpad hardware where you cannot press two buttons at once to
emulate the third button due to hardware design. And any touchpad
hardware on which some of the buttons are broken when it comes to it.
It is built into a notebook and works fine for moving the cursor but
due to lack of usable buttons you still need a mouse to use the
notebook.

Many notebooks have built-in touchpad that has only two buttons, no or limited multitouch and is not built in a way that allows pressing both buttons together to trigger the X11 middle button emulation. This is a facility that exists in the kernel already and allows mapping the missing button(s) to keys near the touchpad. Easy, works with anything that uses the Linux input events (ie does not depend on X11). Thanks Michal

I'd rather we did not promote from drivers/macintosh to other platforms,
but rather removed it. The same functionality can be done from
userspace.
What hardware do you believe would benefit from this and why?
Thanks.
