5.2. 辅助功能

Some users may need specific support because of e.g. some visual impairment. Most accessibility features have to be enabled manually. Some boot parameters can be appended to enable accessibility features. Note that on most architectures the boot loader interprets your keyboard as a QWERTY keyboard.

5.2.1. Installer front-end

The Debian installer supports several front-ends for asking questions, with varying convenience for accessibility: notably, text uses plain text while newt uses text-based dialog boxes. The choice can be made at the boot prompt, see the documentation for DEBIAN_FRONTEND in 第 5.3.2 节 “Debian 安装程序的参数”.

5.2.2. 板卡设备

一些辅助设备实际上是插入计算机里面的板卡,它们直接从显存里面读取字符。要让它们工作,需要使用引导参数 fb=false 禁止使用 framebuffer。然而这会减少可用语言的数量。

5.2.3. 高亮主题

For users with low vision, the installer can use a high-contrast color theme that makes it more readable. To enable it, append the theme=dark boot parameter.

5.2.4. Zoom

For users with low vision, the graphical installer has a very basic zoom support: the Control++ and Control+- shortcuts increase and decrease the font size.

5.2.5. 预置

另外,Debian 可以使用预置进行完全自动安装。相关文档参见 附录 B, 使用预置自动进行安装

5.2.6. Accessibility of the installed system

Documentation on accessibility of the installed system is available on the Debian Accessibility wiki page.
