设置 3M 串行触摸屏

很长一段时间以来，我一直在尝试让串行 3M 触摸屏在 Ubuntu 10.04 上工作。

我能找到的最接近我需要的帖子是这个： http ://ubuntuforums.org/showthread.php?t=1508944&highlight=3m+touchscreen

不幸的是，我到达了我触摸屏幕的地方，鼠标跳到了右上角，就是这样。校准软件并没有真正起作用（直接来自 3M）。有时它不会启动，或者它有问题。

现在看来问题与校准软件无法识别连接的触摸屏有关。通过对安装脚本进行一些更改，我能够正确安装校准软件。

# 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=""

# These symobls point to system and applictaion directories other than
# those specific to the MT7 software

SEDir1="/usr/selinux/booleans"

# 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
# SELinux systems. On most systems SEGivePermission is texrel_shlib_t.
# Change this variable if another security type is appropriate.
SEGivePermission="texrel_shlib_t"

# 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
# /etc/X11/xinit/xinitrc.d and /etc/X11/Xsession.d without a suffix. If
# your distribution requires another location or requires a suffix on the
# file, set these symbols.

很久以前我也在超级用户上问过这个问题，尽管除了 Ubuntu 论坛的链接之外，什么都没有。如果我没记错的话，Ubuntu 论坛上的任何人都没有比将我指向同一篇文章的帮助很大。似乎“触摸屏”是一个很少有人知道的专业话题。

我的问题：

1 有什么技巧可以让它正常工作吗？我的主要问题似乎是 10.04 中较新的引导过程。

2 任何替代校准软件或触摸屏驱动程序可能有效或值得尝试？（串行，不是 USB）。

似乎驱动程序未正确启动。校准软件和控制面板由于某种原因没有检测到控制器。我目前的假设是 init 脚本不正确，很可能是由于 Ubuntu 的启动过程发生了变化。

编辑：

看来我现在可以正确运行控制面板脚本了，我遇到了 Java 问题，但我只需要以不同的方式执行它。现在我有控制面板和校准软件无法检测到触摸屏的问题。一切都在运行，但就是找不到它，即使它已连接并且如果我手动启用屏幕它也会响应。

错误是“触摸屏 1 不存在”。
