[maemo-developers] Mapping the N900 keyboard?

[From: Qole]

I am still hoping for some more help with remapping the N900 keyboard (see
quoted message below).

I have come across a problem I believe is related, and it is much more
urgent for me to identify and fix the problem.

When I start a nested Xephyr X Server on the N900, the desktop environment
that I run in that X Server (LXDE, on DISPLAY :1) does not seem to have
access to the keyboard. No keyboard presses are passed to DISPLAY :1 at all.
When I press the key combination to get to the Dashboard (CTRL-Backspace), I
am taken to the Dashboard, which suggests that maybe Hildon desktop is not
"letting go" of the keyboard.

I have tried using xkbcomp as described below to copy the keyboard mapping
to display :1, but it doesn't help.

Any help or suggestions?
