Setting (non-us) keyboard layout about cage HOT 3 OPEN

export XKB_DEFAULT_LAYOUT=de should be enough for Cage.

How are you starting Cage?

from cage.

My (first) Cage application was freerdp2 in X11 and Wayland mode - syntax/start is with:

cage wlfreerdp -- /v:{rdp-ip}
or
cage xfreerdp -- /v:{rdp-ip}

In both cases keyboard does not change from "us" -
not in the freerdp authentication dialogue, nor in the rdp session itself.
I just installed/cross-checked the app xterm with

cage xterm

and keyboard was set succesfully to "de".
So the issue might (only?) be a freerdp related one...

from cage.

I testet other apps now and export XKB_DEFAULT_LAYOUT=de /setting keyboard layouts worked fine with Cage until now.

The problem seems to be caused by xfreerdp. Their documentation tells something about a "keyboard layout detection"
https://github.com/FreeRDP/FreeRDP/wiki/Keyboard#keyboard-layout-detection
(I dont understand the purpose - why not using the system settings?)
Their process seems to rely on some fancy X11 infrastructure that is not presesent in a pure (X)Wayland\Cage config.

For me (and possible other users of freerdp) the following workaround allows the setting of an keyboard layout with freerdp in a wayland/cage environment:

cage wlfreerdp -- /v:{rdp-ip} /kbd:0x{layout-id}

where layout-id is 0407 for german - other IDs could be find here:
