Hello Vincent,
I figured out where the problem is: the swiss german keymap ini was
missing. I copied the german keymap ini (/etc/xrdp/km-0407.ini
to /etc/xrdp/km-0807.ini) and the keyboard works. The german keyboard
layout is close to the swiss german one but there are some differences:
for example the "@" is not there. Do you have an idea how to modify the
new keymap file? On the swiss german keyboard the "@" is altgr + 2.
In the [altgr] section of the newly created keymap file is for example
key8=0.0 or key9=65307:27.
How do I find out what to modify?
Thanks,
Marco
