我在使用 Debian 9 + xfce + xrdp 时遇到了问题。
问题是当我通过 RDP 重新连接时，额外的布局消失了。
我不确定这是否正是您要寻找的，如果不是，我深表歉意。
也许我的经验会帮助你弄清楚如何解决你的问题。
另外我不知道它是否适用于您的 xrdp 版本。
例如这里是Russian keyboard 的解决方案。
当您启动新的 RDP 会话时，它会将所有键盘布局设置恢复为默认值。
所以有两种方法可以解决。
在任何 RDP 登录后运行命令以将您的设置更改为首选。
setxkbmap -layout us,ru -variant ',winkeys' -option 'grp:alt_shift_toggle,grp_led:scroll'
或更改 xrdp 配置以使其使用您想要的设置。
帮助我更正文件 /etc/xrdp/xrdp_keyboard.ini
（注意 [rdp_keyboard_ru] 和 [layouts_map_ru] 部分）
您可以通过类比将其用于其他语言。
这是我的 /etc/xrdp/xrdp_keyboard.ini 文件的示例。
您可以在文件末尾看到我使用了我的自定义集：
;
; RDP Keyboard <-> X11 Keyboard layout map
;
; How this file works:
; 1. load the file and scan each section to find matching "keyboard_type"
; and "keyboard_subtype" based on the values received from the client.
; If not found, then jump to default section.
; 2. in the selected section, look for "rdp_layouts" and "layouts_map".
; Based on the "keylayout" value from the client, find the right x11
; layout value.
; 3. model/variant are inferred based on the "keyboard_type" and
; "keyboard_subtype", but they can be overridden.
;
;
; RDP Keyboard Type (http://msdn.microsoft.com/en-us/library/cc240563.aspx)
;
; 0 is not a valid value
;
; 1 - IBM PC/XT or compatible (83-key) keyboard
; 2 - Olivetti "ICO" (102-key) keyboard
; 3 - IBM PC/AT (84-key) or similar keyboard
; 4 - IBM enhanced (101- or 102-key) keyboard
; 5 - Nokia 1050 and similar keyboards
; 6 - Nokia 9140 and similar keyboards
; 7 - Japanese keyboard
;
; RDP Keyboard Subtype is vendor dependent. XRDP defines as follows:
;
; 0 is not a valid value
;
; 1 - Standard
; 2 - FreeRDP JP keyboard
; 3 - Macintosh
; ... - < any vendor dependent subtype >
;
; The list can be augmented.
;
; default
[default]
; keyboard_type and keyboard_subtype is not read for default section. It
; is only a placeholder to keep consistency. Default model/variant are
; platform dependent, and could be overridden if needed.

; automatically based on keyboard type and subtype
