I had a little experience with multi-touch devices, so I was happy to use for a while iiyama TF2234MC multi-touch monitor with Debian Wheezy. It was quite pleasant experience with a little bit of adventure.

My adventure with Software

At first I opened product web-page and downloaded Linux touch drivers, but currently only kernels 2.4 and 2.6 are supported, but I needed something working with kernel 3.2.

I have contacted support and was directed to the Touch-Base Ltd a leading developer of touchscreen and pointer device drivers. This multi-touch monitor was probably released recently as I needed to use a little workaround to get it working, so I sent driver assistance request providing technical information and describing my problem. After a couple of hours I received information that device was added to the database and is supported immediately after software installation.

Installation

Additional notes

If the multi-touch mouse does not start after reboot at the login screen then execute the following command.

$ sudo /opt/tbupddlx/tbxuser.pl /etc/gdm3/Init/Default

The free version gives 50 mouse clicks between calibration, or system reboot.
