Cannot open Onscreen Keyboard in Xorg

[Juan Martinez]

Ubuntu 18.10 / GNOME Shell 3.30.1
ALSO
Ubuntu 18.04 LTS / GNOME Shell 3.28.1

Steps to reproduce on our end:

- Login (Xorg as default)
- Attempt to swipe up with finger from below screen
    RESULT: It draws a thin vertical (desktop) selection box, but no OSK
- Logout
- Log back in, after first hitting 'gear' button to select 'Ubuntu on Wayland'
- ps -e | grep Xwayland #shows 'Xwayland' process is running
- Repeat swipe up with finger from below screen
    RESULT: OSK shows up as expected

This has been verified both in 1920x1080 as well as 3840x2160 resolutions (also with various scaling options selected)

Issue is also logged upstream: https://gitlab.gnome.org/GNOME/gnome-shell/issues/839

Thank you for your bug report. Can you add your journalctl log after triggering the issue? Swipping from the bottom on an inspiron 11 using the Ubuntu (x11) default session works here on bionic & cosmic

Adding journalctl output as requested

It may be worth mentioning that we are unable to reproduce the error on some more esoteric models like rugged machines.

One theory is that Xorg/GNOME may have different thresholds than Wayland for detecting the swipe-up gesture and this may be impacted by the particulars of how displays report touch information

FAIL: Precision 5530
 - Max "ABS_Y" value from evtest is 7743 (the highest Y-value for touch observed in testing)
                - Note 7743 doesn't seem to have an obvious relationship with the screen resolution, if that is significant
 - Hardware = "Wacom HID 486A Finger"

PASS: Rugged mobile (different touch hardware)
 - Max Y "ABS_Y" value in evtest is 3840 - this is the same value as the vertical screen resolution
        - Hardware = "Atmel maxTouch Digitizer"
        - No issues on X or Wayland triggering the OSK

Status changed to 'Confirmed' because the bug affects multiple users.

Tagging rls-ff-notfixing, would be nice to fix but it's not a recent regression nor impacting most users so not a rls target atm

But it worked before for me before, see duplicate https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1866556
And the part where it does not appear at all occurred in the past and was fixed: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1760399

Dropped the champagne tag as not deemed release blocking.

https://gitlab.gnome.org/GNOME/gnome-shell/issues/2378 is another report specific to configurations without a physical keyboard. Could you give more details on the configuration you are using and test if it works better under wayland for you?

"Won't Fix": The upstream bug has been closed because the reporter deleted their account. And this launchpad bug has gone unanswered when more information was requested 3 years ago.
