to know the scan codes sent by various keys it is better to boot a
|
|
2.4 kernel. Since 2.6.9 there also is the boot option atkbd.softraw=0
|
|
that tells the 2.6 kernel to return the actual scan codes.
|
|
+
|
|
+ .SH NOTES
|
|
+ The raw scan codes are available only on AT and PS/2 keyboards,
|
|
+ and even then they are disabled unless the
|
|
+ .B atkbd.softraw=0
|
|
+ kernel parameter is used.
|
|
+ When the raw scan codes are not available, the kernel uses a fixed built-in
|
|
+ table to produce scan codes from keycodes. Thus,
|
|
+ .BR setkeycodes (8)
|
|
+ can affect the output of
|
|
+ .B showkey
|
|
+ in scan code dump mode.

will assign the keycode 112 to it, and then
|
|
.BR loadkeys (1)
|
|
can be used to define the function of this key.

|
|
+ USB keyboards have standardized keycodes and
|
|
+ .B setkeycodes
|
|
+ doesn't affect them at all.

|
|
Some older kernels might hardwire a low scancode range to the
|
|
equivalent keycodes; setkeycodes will fail when you try to remap

.SH BUGS
|
|
The keycodes of X have nothing to do with those of Linux.
|
|
Unusual keys can be made visible under Linux, but not under X.
|
|
+
|
|
+ .B setkeycodes
|
|
+ affects only the "first" input device
|
|
+ that has modifiable scancode-to-keycode mapping.
|
|
+ If there is more than one such device,
|
|
+ .B setkeycodes
|
|
+ cannot change the mapping of other devices than the "first" one.
