Dell Duo touchscreen not working on plasma, works everywhere else

[Volta500]

Hello all,
I just got a dell duo to play with, and the first thing i did was remove the broken windows install and install kubuntu.
The install went smoothly, even the touchscreen worked in the installation, but when I got to the desktop, I ran into the following problem:
Plasma elements do not respond to touch. The touchscreen works well on all other applications but in everything plasma the cursor moves to the proper location, but it doesn't "click". If I change the report mode in the eGalax touch drivers to left click on touch, it works fine but this obviously breaks grab and drag gestures, which makes things like scrolling impossible in tablet mode!
I have done anything I could think of: Uninstalling eGalax drivers and going back do evdev, same problem, lost right click. Messing around with egalax config ini file: changed every setting that could be related, still same problem.
Does any one of you have an idea what could be happening? It must be something about how Plasma handles clicks, somehow being less "sensitive" than others.

I tried installing ubuntu desktop and in unity everything works fine, except one little thing: the menu button in google chrome. It turns black like in mouseover but doesn't register a click. Maybe this is a clue to the underlying problem

BTW the touchpad works perfectly, im able to click everything so it is something touchscreen related

Thanks,

EDIT: I will try debian with KDE, see how that goes.
EDIT2: Everything works perfectly on Debian, so il'l go with that! Good excuse to test a new distro!
I'll leave this post to maybe help others that that also run into a similar problem.

I'm actually rather surprised at this, because non-touch Plasma (from what I understand) cannot differentiate between click-to-select and point-to-drag. Would you mind describing in more detail what you're seeing with your KDE on Debian setup?

Also -- I'm curious to know more about your setup. Please show the outputs of:

lsb_release -a

uname -a

kded4 --version

sudo lshw -short

xinput --list

In Debian Wheezy, im seeing what i would expect: if i tap on an item on a panel (like the kickoff launcher, an application in task switcher or an icon in system tray), it opens it just as if you would have clicked it with a regular mouse. The same goes for plasma widgets: touching in them is same as clicking, starting to drag anywhere moves it. It can be a tad annoying as you do not have hover or right click (not plasma related, tap-and-hold sends left click before right click, causing you to open something and then right click. Still have to look into that) but it works ok.
I tried Plasma Active but had no luck getting it to work. The cd install goes ok untill first boot, instead of showing the desktop, severe graphical issues with plasma occur. Plus that there is afaik no 64 bit version wich is a bit of a waste. In the kubuntu active package installed from kubuntu, i get no cursor with the trackpad and the touchscreen is non-operational. Could be just a driver install but that would be quite hard without a mouse. That combined that this is a netbook-tablet convertible so a touch optimized ui may be quite annoying to use with keyboard-mouse-touchscreen combo.

It is interesting that it lists a sleep button as there isn't one
