另一个没有查询keysym, 只获取了keycode的代码:A X11/Xlib program that reads the KeyPress and KeyRelease events from the window and prints them to the standard output. Used to debug the keyboard within X. 2. 如何修改keycode到keysyms的映射关系? xmodmap > $ xmodmap -grammar xmodmap accepts the...

匹配USB键盘:evdev:input:b0003* (匹配所有USB总线上的input类型的设备)虽然这种方法不止可以匹配到键盘,但是事实上其他设备也不会产生和键盘一样的扫描码输入KEYBOARD_KEY_<scancode>,所以一点问题也没有。 匹配笔记本电脑内置键盘:evdev:atkdb:dim* (匹配所有dmi总线上的at键盘)一般情况笔记本电脑也只有一把内置键...
vi OKT507-linux-sdk/kernel/linux-4.9/.config 2. 添加key节点 添加结点需要我们到设备树中进行添加,设备树是一个描述硬件的数据结构,甚至你可以将其看成一个大结构体(这个结构体就是平台,成员就是具体的设备),将硬件的配置从linux内核的源码中提取出来。 下面打开我们的T507设备树文件,如下: vi OKT507-linux-...

I've xmodmap'ed menu to escape because of my broken keyboard key and this has worked on every single application I've ever used, all but Source Engine of course. xdotool is extremely buggy when in a fullscreen game window so that's not a solution, no such X11 option for menu:escape ...
