Yeech! The problem with keycodes >255 was first reported in 2007:
And as of today (may 2010) they still did not fix it. So I wrote a small utility based on kbd's showkey that reads keycodes and uses Xtst to stuff events into X. This hack is ugly as hell and needs suid to be able to read /dev/console. Yikes. But there is no other easy fix.
add-apt-repository ppa:rm-isaev/rawkeybind apt-get update apt-get install rawkeybindOtherwise download source code rawkeybind-0.1.tgz, unpack and issue:
./configure && make && sudo make install
sudo chmod u+s /usr/local/bin/rawkeybind.
echo /usr/local/bin/rawkeybind -f >> ~/.xsessionrc
and restart X.
rawkeybind -dnfto determine keycode that needs to be mapped, then find desired action in
/usr/include/X11/keysymdef.h. For example if we want to map Microsoft Natura zoom key down to down arrow, look for
XK_Downkeysym in the
#define XK_Down 0xff54 /* Move down, down arrow */run
rawkeybind -dnfand press zoom key down, you'l see something like
keycode 0x1a3 press keycode 0x1a3 releaseThen press ^C and add this line
0x1a3:0xff54:Microsoft Natural 4000 key downto
If you create some reasonable translations for your device, email them to me and they will be included in the next version of the program (unless they fix this stupid bug).
