2: keyboard: function keys and numlock

2007-12-25 11:14:00

A couple of weeks ago I posted a question asking how to turn the NUM LOCK

key on and program the function keys at boot time or on starting Openwindows.

I got some requests for a SUMMARY from this list but I did not have an answer

at that time on turning on the NUM LOCK key.

After talking to SUN tech support I got the following that I would like

to share with you.

--> Included message

The *state* of a Num_Lock modifier (or any modifier) can only be

altered by user action, not X client requests.

However, the problem you describe above lends itself nicely to the

simple solution of just mapping the keypad keys such that the only

possible interpretations are numeric. Presto! - global and permanent

"Num_Lock".

Run "xmodmap -pk | grep KP_ >some_file". Edit the file (.xmodmaprc

might be a good choice for the name) to change the lines to xmodmap

expressions that eliminate non-numeric keysyms from the mappings

(you can also eliminate any lines where the mapping is already numeric

keypad only), e.g.:

75 0xffd8 (F27) 0xffd8 (F27) 0xffb7 (KP_7) 0xff50 (Home)

becomes:

keycode 75 = KP_7

Then modify the .xinitrc or .xsession file to invoke "xmodmap .xmodmaprc".

(BTW, newer versions of xmodmap have a "-pke" option that makes this a

little easier.)
