在 ubuntu 20 中修改键盘布局

我的 hp 笔记本电脑有一个德文键盘，似乎是美式键盘的相关版本。因此，它缺少<>|通常位于德语键盘上 l-shift 右侧的键。

这显然很烦人，到目前为止，我还没有找到可以生成<or的替代键组合>。似乎有一个名为 E2 的键盘布局非常适合我的键盘（https://de.wikipedia.org/wiki/Tastaturbelegung#Tastaturbelegung_E2）。但是，开箱即用的 Ubuntu 20 似乎不支持它。

那么有谁知道我如何获得 linux 的 E2 布局，或者我如何为<和>. 我在网上找到的关于如何自定义键盘布局的教程似乎已经过时，我无法让它们在 Ubuntu 20 中工作。

这是我尝试过的：

我尝试按照本教程https://help.ubuntu.com/community/Custom%20keyboard%20layout%20definitions进行操作。

我试图重新映射ALTGR-Y到<并ALTGR-X使用>xkb。

我目前正在使用键盘布局German (Macinthosh)，所以我编辑了/usr/share/X11/xkb/symbols/macintosh_vndr/de文件。

在 xkb_symobls “基本”部分中，我添加了以下映射：

    key <AB01> {        [         y,    Y,      less,   guillemotleft           ]       };
    key <AB02> {        [         x,    X,      greater,        guillemotright          ]       };

然后我重新启动，但ALGR-Y仍然ALTGR-X给我错误的字符。:(
