just follow the steps:

install evtouch

sudo apt-get install xserver-xorg-input-evtouch

see if the device is loaded

cat /proc/bus/input/devices

should see something like this

Great work!

About Damien Baraka, problem; I had the same issue, because the /dev/input/event# keeps changing after reboot, so the configuration was applied on the usb mouse! Changing event number with the correct one and restarting X resolved the issue.

The problem I have is that the event number keeps changing randomly after every reboot (even if I removed USB Mouse).

Any Idea how to force the usb panel driver get the same event number every time?

For some reason I found your post from the inbox just now, almost 2 months later. Is the problem still topical or did you managed to solve it?

This is a great help.

But I’ve hit a brick wall, I can’t seem to fix the whole SWAP XY and Rotate C/CW issue.
I have inputted the options into my xorg.conf file but upon restarting the Xserver it remains all mixed up.

Here is a copy of my xorg.conf file:
Section “Device”
Identifier “Configured Video Device”
EndSection

Section “Monitor”
Identifier “Configured Monitor”
EndSection

Section “InputDevice”
Identifier “touchscreen”
Driver “evtouch”

PLEASE HELP!!!!

Really need to get this working ASAP for work.

Thank you again and I look forward to your reply.

Here are some thoughts/experiences on touch screen smart home info kiosk usage:

- Instantly available Internet access has been the most important thing for my family. Modern web services are heavily based on javascript and flash, so you need to have a computer that is powerful enough. On the other hand, there is not much that you can do to the Internet based content itself, except that you can set the text size large enough so that links can be more easily selected with touch. Luckily, web based services usually do not utilize right mouse click or mouse dragging a lot, as these are difficult with touch control.

- Based on heavy reliance to Internet services anyway, I consider the web browser the primary front end. You can always build your custom smart home application to utilize web interface. That’s probably what you should do anyway, to enable smarthome control with windows/mac/linux boxes and phones. From various browsers, at least Firefox can be pretty well customized. You’ll appreciate that, as you can adjust it for increased usability with touch.

- Currently all desktops are primarily targeted for mouse and keyboard use, and thus are not very well suited for touch based use (my opinion). However, I consider it too laborious for a personal project to do anything more than minor theme etc. adjustments, as the touch control concept should be taken into account already in the application level when creating the user interface. This work is happening right now in smartphone OSes like Symbian, Maemo and Android, but not yet on desktop OSes. The latter may support touch, but they do not really embrace it yet in the application level.

Great site, I am just starting to embark on such a project, in fact what I really aim to do is to create a smart/home info kiosk as you mentioned above. In fact I have been looking for ideas for to what to use as a front end etc… I would really appreciate if you let me know what you used to finally drive the user interface that you use etc…..

Thanks !!
