Setting up a 3M Serial Touchscreen

I've been attempting for quite a long time to get a Serial 3M Touchscreen to work on Ubuntu 10.04.

The closest post I could find to what I needed was this one: http://ubuntuforums.org/showthread.php?t=1508944&highlight=3m+touchscreen

Unfortunately, I get to where I touch the screen and the mouse jumps to the top right corner and that is it. The calibration software doesn't really work (straight from 3M). Either sometimes it won't start, or there is something wrong with it.

It now looks like the problem has to do with the calibration software not recognizing the attached touchscreen. With some changes to the installation script, I was able to get the calibration software to install properly.

# This script installs the MT7 touch screen driver
# During installation, all directories must be writeable.
#

# These symbols point to where the MT7 software binaries and data reside.
# The script attempts to detect where the installation kit is. If this
# fails, you need to set BinDir.
# The data directory must be on writeable media. The script normally uses
# the directory where the installation kit resides as the data directory.
# If you need the data directory to be elsewhere, set DataDir.
BinDir=""
DataDir=""

# If desired, define a file to contain driver startup options and set
# the TwDrv_Cfg symbol to the full path of the file. Normally this is
# not needed.
TwDrv_Cfg=""

# This symbol points to where the Java VM binaries reside.
JavaBinDir=""

# The InitDir symbol points to where this script places an 'init' script.
# If left blank, this script first looks for /etc/init.d and then /etc/rc.d.
# If this is not appropriate or this script otherwise fails, set this value.
InitDir=""

# This symbol enables permission for some MT7 shared objects on

# This symbol affects when the X input driver converts raw touch screen
# coordinates into screen coordiates. Normally, the X input driver reports
# the raw coordinates to the X server which then calls an conversion
# routine. Some versions of the X server expect the initial report to
# contain converted coordinates. If your touch behavior is off and
# calibration does not address the problem, set ConvertAtRead to true.
ConvertAtRead="false"

# This symbol defines the name of the xorg.conf file to generate if one is
# not found. Starting with X server version 1.5, this file is not
# automatically generated. This file is needed for MT 7 for Linux to work.
# If you want the file to reside elsewhere, set this symbol.
XorgConf="/etc/X11/xorg.conf"

# These symbols define where the 50MT7-xinit script needs to go and what
# suffix it requires. The script places this file automatically in

# your distribution requires another location or requires a suffix on the
# file, set these symbols.

Usually this puts out this error, although I don't think the errors are critical (warnings?):

I also asked this question on Super User quite a long time ago, although other than the link to the Ubuntu forums, nothing. If I recall correctly, no one on the Ubuntu Forum was very helpful beyond pointing me to the same post. It seems "touchscreens" is a specialized topic that not a lot of people know much about.

My questions:

1 Any tips to get this to work correctly? My major problem seems to be the newer boot process in 10.04.

2 Any alternative calibration software or touchscreen driver that may work or is worth trying? (serial, not USB).

It seems that the the driver is not initiating correctly. The calibration software and control panel do not detect the controller for some reason. My assumption at the moment is that the init script is not correct, most likely due to changes in Ubuntu's start-up process.

Edit:

It seems I can now run the control panel script correctly, I was having problems with Java, but I just had to execute it differently. Now I have the problem that the control panel and calibration software cannot detect the touchscreen. Everything runs, but just can't find it, even though it's connected and it responds if I enable the screen manually.

The error is, "touchscreen 1 is not present".

On maverick,add this PPA and try

ppa:utouch-team/utouch

Please see this to get help with MultiTouch in Ubuntu: https://wiki.ubuntu.com/Multitouch#Community%20Help

Make sure you include the result of lsusb when you ask your question there. Thank you!

However this may not be enough to properly configure your device drivers. I would suggest filing a bug.
