[Bug 1774242] Re: Wacom touchscreens should use libinput, not wacom driver

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).

I tried the upstream patch on xserver-xorg-input-wacom 1:0.36.1-0ubuntu1 on 18.04, this issue is fixed. commit 31a5405f7d9405bc514585709161287b0c67386e Author: Jason Gerecke Date: Mon Sep 9 15:32:17 2019 -0700 Change default gesture mode: touchpad=on, touchscreen=off A large number of users run the GNOME desktop which has its own gesture engine that performs actions on touchscreens. These gestures are much better than the ones we provide, so lets disable our engine by default for touchscreens. Note that GNOME doesn't do anything with touchpad gestures, so we leave them enabled by default. 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.

[Bug 1774242] Re: Wacom touchscreens should use libinput, not wacom driver
Just a note (mostly to other distro maintainers that may come across this) that an alternative to completely disabling the Wacom driver's touchscreen handling is to just add `Option "Gesture" "Off"` to the touchscreen section of 70-wacom.conf instead. The driver currently defaults to consuming all multitouch events to power its own (very limited) gesture recognizer, but the above config option will let it pass everything through to the desktop and applications. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1774242 Title: Wacom touchscreens should use libinput, not wacom driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xf86-input-wacom/+bug/1774242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you so much for posting this simple fix I changed the line from Driver "wacom" to Driver "libinput" like you said. Now multitouch is working correctly in Kubuntu. I have a Lenovo Flex 5 "14 (also known as the Yoga 520 outside the US) which also uses Wacom AES hardware. I could not get multitouch to work at all with the touchscreen. This was bad because multitouch allows me to easily zoom/move around the canvas when I'm drawing in Krita and also zoom and go forward/backwards in google chrome. The touchscreen with the driver set to wacom driver is awful! In addition to no multitouch I couldn't even do simple scrolling smoothly. I agree that the "Wacom touchscreen class" should switch to "libinput" drivrt by default.
