Has anyone developed keyboard driver for X ? Or does anyone know current
situation?




XFree86 4.x has loadable drivers, including keyboard. 



really ?
i thought the keyboard is compiled into server???



There are 2 keyboard drivers in XFree86 4.3.0. One is the legacy X
driver which is part of the base X server and the 2nd one is a new
Xinput based driver which is dynamically loadable. The name of this
loadable module is "kbd" (while the legacy driver is named
"keyboard").




so what is the deal then with the keyboard ....

my problem now is that i need to prevent X to generally map cetrain Scancodes to a generic keycode ...which then makes some extra buttons on my Tablet Pc send the samy keycode as Key-Up and i cannot put function on this keycode so i ll loose my KEY_UP also ...
i changed also the file atKeynames .h accordingly ...

I read then that the keyboard is compiled into the server , and also changing the "Driver" "Keyboard " into
Driver " "kbd" did not start the X-server ....

the scancodes i need to be free to get a free keycode are

0x5a and 0x59



It looks like all of the other scancodes like these that are currently
returned for various 2-byte codes need to be remapped.  I recently did
this for 0x5c, which is KP_Equal on Macs.  The attached patch (relative
to the current CVS trunk) should handle the rest of them.  Let me know
if it works for you.  If it does, I'll commit it.  The patch handles both
the built-in keyboard driver, and the modular "kbd" driver.

If we were starting over with this, we'd handle the mappings more cleanly.
We should probably do that for 5.0.



pls tell me some more things ...

i did these changes by hand in the vanilla X-4.3 source ....
then i did only recompile the kbd.o module and started but still i get KEY_UP as keysym and keycode 98 ( using xev ) for my key with scancode 0x5a and KEY_HOME and keycode 97 for my key with scancode 0.59 ... .and i did use kbd as driver in my InputSection !!!
will i have to recompile the whole X-server (XFree86 executable ) to make these changes work ???

So the question is what parts will be needed to exchange to make these cchanges valid !!!
