Description paul 2010-08-24 19:25:06 UTC
Version:           4.5 (using KDE 4.5.0) 
OS:                Linux

I read kde announcement for kde 4.4 that multitouch is supported starting with that version.

I now have a touchscreen that supports multitouch on linux as well as windows7.

I want to take advantage of kde multitouch interface, but do not know how to get it working.

Reproducible: Always

Steps to Reproduce:
Login to kde and multitouch does not work.

KDE supports multi-touch whereever Qt supports it, which right now is just on Windows 7. X11 does not have multi-touch support yet, but it is proposed to be added in the future. See http://www.phoronix.com/scan.php?page=news_item&px=ODQ4MQ for a first proposal of the specification.

I have tried utouch on ubuntu development for Oct 2010 release, as described here:

It seems waiting for multi-point X and qt revisions may not be necessary.  Does kde plan to look at utouch alternative, which is available now?

What's the current status on this? I can't get multitouch to work with kde 4.9.5 (haven't tried 4.10 yet)
Comment 4 Christoph Feck 2013-03-07 21:36:14 UTC
I do not know the current status of X11 multi-touch support, and whether Qt supports it on X11. You could ask on the qt-interest mailing list.
Comment 5 aditsu 2013-03-07 22:23:50 UTC
X11 is supposed to support multitouch for a long time already: http://cgit.freedesktop.org/xorg/driver/xf86-input-evdev/log/?qt=grep&q=multitouch
As for Qt on X.. I've seen conflicting reports and no clear information. Their touch examples are not working for me. I guess I'll try to ask them.
