still waiting on the touchpad edge detector tool output from comment #6. Please
re-open when the requested information is available.

I did some informal testing, seems that at around 20mm it's much more
convenient. Which is quite close the the 25% mark of my touchpad (101mm wide).

But again, by how i operate the laptop i can't normally actually see the
marker. So it's not that surprising that a convenient size is going towards the
same size as non-marked touchpads.

Run the touchpad-edge-detector tool (part of libevdev) and that should tell you
the correct axis ranges. Then file a bug against systemd and cc me on it
(@whot) so we can get this into the hwdb.

Thanks for the explanation. My axis must be out of whack, because the middle
appears to the left of the center dividing line on the device. Am closing as
invalid.

(In reply to Paul Johnson from comment #3)

that's not true. look at
https://cgit.freedesktop.org/wayland/libinput/tree/src/evdev-mt-touchpad-buttons.c#n575
the left edge is 5mm left of the middle, the right edge 5mm right of the
middle.

Unless your axis ranges are out or there's some other bug interfering, the
middle button is centered.

sigh. I absolutely hate loaded language like this. No, I didn't make it too
small on purpose, I made it *smaller*, with an explanation and a link to the
bug. Get your act together and assume that people have good intentions.

I'm happy to increase the size until it becomes usable for me and report back.

However part of the point is that while there might be a visual guide (but no
tactile guide) most of the time while using the touchpad it's not actually
visible (either due to my hands being over it or because it's a low-constrast
guide which is almost invisible in low-light). So practically, for comfortable
usage for me, i suspect it shouldn't be treated any different from a touchpad
without the mark.

in tp_init_softbuttons(), edit the width to e.g. 12mm, does that help? At what
size does it become useful?

Bug ID: 98236
   Summary: Middle mouse button hard to hit on dell touchpad
   Product: Wayland
   Version: unspecified
  Hardware: Other
OS: All
Status: NEW
  Severity: normal
  Priority: medium
 Component: libinput
  Assignee: wayland-bugs@lists.freedesktop.org
  Reporter: sjo...@luon.net

On dell touchpads the middle mouse area is shrunk by libinput as there is a
visual guide (a small line in the middle ofthe touchpad). 

However this makes it very hard to hit without looking at the touchpad
(including moving ones hand aside as it often hovers over the line). Also in
low-light conditions the visual guide just isn't easily visible, making things
even more awkward.
