xrdpでMac版WindowsAppのkeymap対応

MacのWindowsAppからxrdpにrdp接続するとusキーボードになってしまうので調査

~$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.04
DISTRIB_CODENAME=noble
DISTRIB_DESCRIPTION="Ubuntu 24.04.4 LTS"
~$ xrdp -v
xrdp 0.9.24
(略)
~$ setxkbmap -print
xkb_keymap {
        xkb_keycodes  { include "xfree86+aliases(qwerty)"       };
        xkb_types     { include "complete"      };
        xkb_compat    { include "complete"      };
        xkb_symbols   { include "pc+us" };
        xkb_geometry  { include "pc(pc104)"     };
};
~$ tail -n30 /var/log/xrdp.log | grep key

/etc/xrdp/km-00000000.iniがないのでusのkeymapにフォールバックしているのでjaのkeymapへのシンボリックリンクを作成

mv /etc/xrdp
sudo ln -s km-00000411.ini km-00000000.ini # MacのWindowsAppが報告するkeymap

rdpで再ログインしてkeymapを確認

~$ setxkbmap -print
xkb_keymap {
        xkb_keycodes  { include "xfree86+aliases(qwerty)"       };
        xkb_types     { include "complete"      };
        xkb_compat    { include "complete"      };
        xkb_symbols   { include "pc+jp+inet(pc105)+us:2"        };
        xkb_geometry  { include "pc(pc105)"     };
};
