类似问题之前有人问过,但没有答案。我无法发表评论,也没有答案,因此我看不出除了再次提问之外还有其他选择。
我有一台 USB 激光演示器 August LP205R,它无法在 GNOME Ubuntu 15.04 上运行,但在 Windows 上可以正常使用 PowerPoint 和 PDF 演示文稿。以下是上一个链接中要求的输出:

我甚至尝试过之前getscancodes
推荐dmesg | tail
的:

我想知道是否有人可以帮助我弄清楚是否以及如何更新或*-keyboard.hwdb
根据上述数据创建新文件,如下所示:
提前致谢! :)
答案1
在网上寻找类似的设备,指出您的设备
1d57:83ed Xenta
,它会创建两个输入设备(鼠标和键盘),标记为RF 2.4G RF 2.4G
带有id=14
&id=13
来自您的命令输出。getscancodes
已在~/Downloads/getscancodes
文件夹中创建但/dev/input/event16
不是相应的事件设备文件。您可以使用以下方法查找相关事件文件:xinput --list-props 14 xinput --list-props 13
然后运行
./getscancodes /dev/input/eventXX
两个事件文件并尝试所有键。如果
getscancodes
不起作用,Ubuntu 存储库中有一个标准工具。试一试:sudo apt-get install evtest sudo evtest
方法解释于如何更改单个设备(Logitech 演示器)的键盘映射?已经过时了。
因此Xubuntu - Logitech 演示器仅部分工作其中有与注释/标题中提到的相同的说明
/lib/udev/hwdb.d/60-keyboard.hwdb
