Xvfb and xkb

[Ashwin Chandra]

After more searching on the web, a lot of people say the Xvfb and keymaps
just don't work correctly (at least in older versions).

Can anyone tell me if they have actually succeeded in getting Xvfb and
setxkbmap working ?

oh, that answers the question then. servers regenerate when the last client
disconnects, so if you do the following, the keymap is reset before anyone
can use it:

Xvfb &
setxkbmap -layout de
/* last (only) client disconnects, server regens with defaults */ xterm /*
has the default keymap now */

tbh, shoft of strace or gdb, I don't know
