Bug Description

Hi ,

I have a dell latitude xt2 notebook with multi touch screen functionality and ubuntu 9.04.

I try some configuration with xorg conf to have my touch screen up and running

Actually I'm able only to use the pen and it works very well.

My problem is that when I try to touch the scree with the finger , the mouse cursor jump on the top of the screen and I 'm unable to select, drag , double click anything.

I attach:
 the output of lspci -vvnn
the /var/log/Xorg.0.log
and /etc/X11/xorg.conf file

thanks

Same for me.
Patches seem to exist (http://ubuntuforums.org/showthread.php?t=1406436), it would be nice if it was integrated in Lucid ...

I have a xt2 with the multitouch N-trig device running maverick 2.6.35-9-generic

Just after boot the touchscreen fails to work, after a while the touchscreen starts to work (few minutes)

Still this N-Trig device should be multitouch, it looks like just identified as a single touchscreen

This looks like a firmware issue. A multitouch N-Trig device should register a "MultiTouch" device with X. The X log posted in comment #3 does not mention any "MultiTouch" device. I have seen this once before on a similar N-Trig device. The solution was to fully update to the latest firmware available from the laptop vendor. I would look for a firmware update from Dell in this instance.

Unfortunately, the firmware updates are Windows executable files. There is no way to update the firmware in Linux yet.

I am moving the bug report to Invalid as it's not really an issue with the Ubuntu kernel.

Changed in linux (Ubuntu):
status: Confirmed → Invalid

I have send a mail to N-Trig and they are working on it

maybe it can be done before release of maverick :)

-> We are currently working on a Linux bundle for Ubuntu.
We should post it on our website within a month.
