Hello Shawn, or anyone else affected,

Accepted xf86-input-wacom into bionic-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/xf86-input-
wacom/1:0.36.1-0ubuntu1.1 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: xf86-input-wacom (Ubuntu Bionic)

Title:
  Wacom touchscreens should disable gestures

Status in OEM Priority Project:
  In Progress
Status in xf86-input-wacom package in Ubuntu:
  Fix Released
Status in xf86-input-wacom source package in Bionic:
  Fix Committed

Bug description:
  [Impact]

  From the original bug:

  "The result is that on my Yoga 920, in a plain X11 session (running
  openbox in my case), the touchscreen acts like a broken mouse: there
  is no multi-touch capability in Qt Quick applications, and clicking
  isn't quite right either."

  [Test case]

  Install the update, note that the touchscreen behaviour is better.

  [Regression potential]

  From the upstream commit:

  "Note that this change will effectively cause a feature regression for
  users of other environments that do *not* have their own gesture
  engines (Cinnamon, KDE, MATE, XFCE, etc.). Users will want to add an
  xorg.conf.d snippet with `Option "Gesture" "on"` to bring back the
  functionality."

  but at least I (tjaalton) haven't heard of any complaints since we've
  disabled gestures in focal (Nov 21st), so the warning might be a bit
  too pessimistic about the impact.

  /usr/share/X11/xorg.conf.d/70-wacom.conf as shipped, has this:

  Section "InputClass"
          Identifier "Wacom touchscreen class"
          MatchProduct "Wacom|WACOM|PTK-540WL|ISD-V4"
          MatchDevicePath "/dev/input/event*"
          MatchIsTouchscreen "true"
          Driver "wacom"
  EndSection

  The result is that on my Yoga 920, in a plain X11 session (running
  openbox in my case), the touchscreen acts like a broken mouse: there
  is no multi-touch capability in Qt Quick applications, and clicking
  isn't quite right either.  I also verified it with Peter Hutterer's
  old cairo-based mt-touch test program.

  I suspect we will get some users mistakenly writing up Qt bugs about
  this if you don't ship a fix.  (Seems to me that already happened at
  least once, actually.)

  Yes, the touchscreen is made by Wacom, but wacom_drv.so has
  historically been only for Wacom tablets and in-screen stylus
  digitizers, and IMO that continues to be the case.  libinput is a much
  better choice of driver for this hardware (so is evdev for that
  matter), so I changed it to Driver "libinput" and got it working.
  (Wayland uses libinput, so in a wayland session, touch already works
  fine in Qt apps on this hardware.)

  I'm one of the Qt Quick maintainers, most concerned with touch
  handling, and I've also written some of the Qt xcb code for dealing
  with XInput touch and tablet devices.  So if you think that there's
  something wrong with Qt, such that it should still work anyway to use
  a wacom driver for a Wacom touchscreen, let me know.  These AES
  devices are still new to me (that's why I got a Yoga, to try it out).
