第 25 章 图形平板

流程

1. 安装提供平板电脑定义文件的软件包：

   # yum install libwacom-data

   包会将平板电脑定义文件安装在 /usr/share/libwacom/ 目录中。

2. 检查定义文件是否在 /usr/share/libwacom/ 目录中存在。

   要正确使用屏幕映射，必须在 libwacom 数据库和 udev 规则文件中包含对您的平板电脑的支持。

   重要

   libwacom 不支持设备的一个常见指示是它在 GNOME 会话中正常工作，但设备没有正确映射到屏幕。

3. 如果您设备的定义文件不在 /usr/share/libwacom/ 中，则有以下选项：

   • 所需的定义文件可能已在 linuxwacom/libwacom 上游存储库中。您可以尝试在其中查找定义文件。如果您在列表中找到了您的平板电脑型号，请将文件复制到本地计算机中。

   • 您可以创建新的平板电脑定义文件。使用以下 data/wacom.example 文件，并根据您设备的特征编辑特定的行。
