Description animtim 2017-07-24 15:29:45 UTC

Touch painting is supposed to be re-enabled on git master, but it doesn't work on linux here. Though zoom and pan touch work...

Only touch related log I have is, when using touch pan and zoom:

krita.input: KisAbstractInputAction "Faire un panoramique du tableau" tried to process event data from an unhandled event type QEvent::Type(TouchUpdate)
krita.input: KisAbstractInputAction "Faire un zoom sur le tableau" tried to process event data from an unhandled event type QEvent::Type(TouchUpdate)

And if I do 
export QT_LOGGING_RULES="krita.input=true" && krita
I don't see any more touch input log.

Does work here on kde neon for what it is worth.

wolthera, do you know which driver is used there for your touchscreen?

evdev or libinput (or another) ? (I'm quite sure it's using libinput here)

In any case, this sounds like an issue with another component in the stack than Krita. It might even be a Qt version issue.

Touch also doesn't work for me (convertible) although it is enabled by default. I've tried it on Ubuntu and Arch Linux (using git master). Touch pan and zoom works as expected. Is this a hardware specific issue?

Comment 5 Halla Rempt 2018-05-25 08:33:43 UTC

Probably it is a hardware issue, or it is a kernel issue, or a library issue. It is, in any case, not a bug in Krita, so it is inappropriate to keep this bug open.
