Hi!

Many new computers have a touchscreen. On linux, it works great as a mouse, but one would like to do more with it.

I was wondering what was the status of KDE and plans for having multitouch support on linux. I have been searching the web with no good answer:

• The question was already asked on this forum in 2010 (https://forum.kde.org/viewtopic.php?t=89708)
• There is a video on youtube (https://www.youtube.com/watch?v=gDadhfHzoLY) from 2009 where plasmoids are rotated with a two finger gesture, showing the "multitouch capabilities of the upcoming KDE Plasma Desktop 4.4, thanks to the new multitouch features of QT 4.6". Was probably not running on linux, though...
• There is the plasma-active project with such great videos and hope! But the last activity on their website is from 2013.
• There is the upcoming plasma 5.2. Will it feature multitouch on linux ?

I am running an up to date Fedora 21. My multitouch hardware is well recognized: the kernel sends multitouch events, and XOrg's evdev drivers seems to interpret them correctly. I have tried the examples in the qt5-qtbase-examples package, and most of them are wroking: I can zoom with two fingers with /usr/lib64/qt5/examples/touch/pinchzoom/pinchzoom, I can draw with up to five fingers with /usr/lib64/qt5/examples/touch/fingerpaint/fingerpaint, I can rotate the knobs in /usr/lib64/qt5/examples/touch/knobs/knobs by putting a finger on them and turning around with another finger. I didn't manage to have any multitouch effect in /usr/lib64/qt5/examples/touch/dials/dials.

Note that those are the examples for qt5. None of the multitouch examples in the qt4-qtbase-examples package work at all. This means, I guess, that I have no hope of seeing any working multitouch in kde 4.xxx. Just for checking, I tried to boot my computer on a usb key loaded with the iso file founded on http://pub.dvratil.cz%20plasma/iso/5.1/, which got plasma 5.1 up and running on my computer, but with no multitouch capability.

Hey, multitouch is rather a big thing, these days. Where is kde on this front ?

Myself, I'm running Kubuntu. No multitouch capabilities there. I tried installing plasma-active at some point (14.04), but that didn't work at all. Some active apps work more or less, but were to buggy to really use.

Chromium works with multitouch (pinch in maps, 2 finger scroll), but thats not KDE exactly.

Installing touchegg give some gestures, but really good (2 finger scrolling works in the wrong direction).

I agree, how can KDE be so beatiful and advanced and not have a consistent touch experience.

Note: I'm running a very low cost Acer C720P Chromebook turned to Kubuntu that beats the **** out of anything similarly priced running win8.
