Public bug reported:
hardware: macbook pro generation 4,1 (feb 2008)
problem: fn key not detected
test: run xev. press fn key. nothing happens.
consequences: home/end/pgup/pgdown don't work.
i was able to fix this issue by compiling my own kernel.
i downloaded linux-source from ubuntu hardy
(VERSION = 2,PATCHLEVEL = 6,SUBLEVEL = 24,EXTRAVERSION = .3)
and revised this file:
drivers/hid/usbhid/hid-quirks.c
used lsusb to grab the id of the internal keyboard device:
Bus 005 Device 003: ID 05ac:0230 Apple Computer, Inc.
and revised the c file accordingly:
/* next line commented out by eitan and replaced with line below;
changing address for device from 0x021b to 0x0230 which is what lsusb tells me
my internal keyboard device id actually is
#define USB_DEVICE_ID_APPLE_GEYSER4_ISO 0x021b
*/
#define USB_DEVICE_ID_APPLE_GEYSER4_ISO 0x0230
rebooting with the new kernel, the fn key now works.
i don't know if this breaks other versions of the macbook pro
and am otherwise ignorant of the linux kernel source code.
thanks,
/ eitan
