Hey,

I have recently bought a Dell Xps One 27. It has a full 27" 10 finger touchscreen.
So far I am only able to use 1 finger.
For what I have read kde has builtin multitouch support (qt).
Do I need to enable this?
Does anyone have experience with using and configuring multitouch on kde?

I have Debian Wheezy installed using 2.6.38-2 kernel from sid.
The xinput-evdev driver in wzheezy does not support multitouch. The driver in experimental does (1:2.7.1-1) . I have this one installed.

I hope someone can help me. There is not much info on the net about this.
I tried to get the utouch-geis lib or ginn lib to work, but I did not had much success.

Thank you
Malic

Hmm, I'm not sure if we do support multi touch actually - at least not with Qt 4, which is what KDE still uses at the moment.
Qt 5 does have some changes here I believe, although i'm not sure how much they function for linux system though.

In any case, configuring X and the appropriate screen drivers (possibly wacom) is your first port of call here I would imagine.

I probably mistaked by looking at plasma-active

I am trying to compile plasma-active inside my debian/kde 4.8 environment. I have never compiled a kde so this could take a while to make it work.
(Currently stuck at: Could not find a package configuration file provided by "KActivities" )
This environment would be really great to use on my touchscreen.

The alternative is Touchegg. It depends on utouch-geiss wich is not in the debian repo so I need to compile it myself also.
There is a kde fork: https://projects.kde.org/projects/playground/base/gestures-kde/

Not much reply here.

update: I have managed to compile the geis and touchegg libraries. They work, but there focus is way off. I will look furhter into that.

For development help, you might want to ask on the active@kde.org mailing list, which is rather active I believe.

Hello,

has anything changed regarding touchscreen display support?
Chromium and Okular have good touch support, but the Plasma desktop does not detect 'clicks'. Do I need to enable something?
