LFS system - customizing keyboard - what scan codes..?


Finally got a stable version out...

I'm trying to figure out how to figure out the scan codes for all the extra buttons that come on these pre-built computers..

2-system I am playing with at the moment: IBM Thinkpad and Dell Inspiron.
I have noticed that the Thinkpad and Inspiron both have specific keyboard support in Xorg6.8.1.

Heres the questions:
1) I have extra buttons on my keyboards, how do I figure out what scan codes they send when pressed?
2) Once past that, is there a way to customize what they do when they are pressed. (I can also program so if that is the case, could you point me in the correct direction??)

I am using something loosely near LFS-5.1.1, only a little closer to bleeding edge.

If you open a shell and run xev it should tell you something about what key was pressed. Read man xev
I don't know how to make use of the information. Try reading man setkeycodes

After also searching through LQ's forums for this problem. (and your help..) I came to this conclusion:

1) showkey fails to show my keycodes (only non-standard)
2) passing showkey -s revealed the following (touched up for easier reading):

Code:
kb mode was XLATE

-------------------------------------
| Press     | Release   | Button    |
-------------------------------------
| 0xe0 0x6c | 0xe0 0xec | e-mail    |
| 0xe0 0x32 | 0xe0 0xb2 | home      |
| 0xe0 0x65 | 0xe0 0xe5 | search    |
| 0xe0 0x66 | 0xe0 0xe6 | go        |
| 0xe0 0x67 | 0xe0 0xe7 | refresh   |
| 0xe0 0x68 | 0xe0 0xe8 | stop      |
| 0xe0 0x6a | 0xe0 0xea | backwards |
| 0xe0 0x69 | 0xe0 0xe9 | forwards  |
-------------------------------------|
3) It seems that when it sends the initial NULL, X and showkey (without -s paramater) assume that is the end of the keysequence and stop. Thus all the applications I try seem to only get 0 / Null / Nothing at all.

4) I am currently looking at this as a possile solution, further testing to come: http://hocwp.free.fr/xbindkeys/xbindkeys.html#download
