BTW the current git sources : n22 ~ # uname -a Linux n22 2.6.23-ge8b8c977 #1 Sat Oct 20 18:16:50 CEST 2007 i686 Intel(R) Pentium(R) M processor 1700MHz GenuineIntel GNU/Linux shows the same behaviour although I hoped that commit f2e1d89 would solve this. sry, I meant commit fba956c Please kill acpid and cat /proc/acpi/events, can you see
"ibm/hotkey HKEY 00000080 00001011" when pressing Fn+End?
>In addition the script /etc/acpi/events/default catches only this case,
can you attach /etc/acpi/events/default and "/etc/acpi/default.sh please?

/etc/acpi/default.sh
No, I can't see this particualr event. However all others are displayed correctly (BTW, it the file name is /proc/acpi/event.
Here's the other file:
n22 ~ # cat /etc/acpi/events/default
# /etc/acpi/events/default
# This is the ACPID default configuration, it takes all
# events and passes them to /etc/acpi/default.sh for further
# processing.
# event keeps a regular expression matching the event. To get
# power events only, just use something like "event=button[ /]power.*"
# to catch it.
# action keeps the command to be executed after an event occurs
# In case of the power event above, your entry may look this way:
#event=button[ /]power.*
#action=/sbin/init 0
# Optionally you can specify the placeholder %e. It will pass
# through the whole kernel event message to the program you've
# specified.
event=.*
action=/etc/acpi/default.sh %e

a small tool to listen to input events
Please compile and run this program on your laptop to see if there is any input events exported by thinkpad_acpi driver when pressing hotkeys.
Please: #cat /proc/bus/input/devices (to see which event channel thinkpad_acpi driver is taking) #gcc input.c and #./a.out x (listen to the input events sent by thinkpad_acpi, where x is the channel number.) press fn_pos and fn+end hotkey and attach the output. tfoerste@n22 ~ $ cat /proc/bus/input/devices I: Bus=0011 Vendor=0001 Product=0001 Version=ab54 N: Name="AT Translated Set 2 keyboard" P: Phys=isa0060/serio0/input0 S: Sysfs=/class/input/input0 U: Uniq= H: Handlers=kbd B: EV=120013 B: KEY=4 2000000 3802078 f840d001 feffffdf ffefffff ffffffff fffffffe B: MSC=10 B: LED=7 I: Bus=0010 Vendor=001f Product=0001 Version=0100 N: Name="PC Speaker" P: Phys=isa0061/input0 S: Sysfs=/class/input/input1 U: Uniq= H: Handlers=kbd B: EV=40001 B: SND=6 I: Bus=0011 Vendor=0002 Product=000a Version=0000 N: Name="TPPS/2 IBM TrackPoint" P: Phys=isa0060/serio1/input0 S: Sysfs=/class/input/input2 U: Uniq= H: Handlers=mouse0 B: EV=7 B: KEY=70000 0 0 0 0 0 0 0 0 B: REL=3 I: Bus=0003 Vendor=046d Product=c03d Version=0110 N: Name="Logitech USB-PS/2 Optical Mouse" P: Phys=usb-0000:00:1d.1-1/input0 S: Sysfs=/class/input/input3 U: Uniq= H: Handlers=mouse1 B: EV=7 B: KEY=70000 0 0 0 0 0 0 0 0 B: REL=103 I: Bus=0019 Vendor=0000 Product=0002 Version=0000 N: Name="Power Button (FF)" P: Phys=button_power/button/input0 S: Sysfs=/class/input/input4 U: Uniq= H: Handlers=kbd B: EV=3 B: KEY=100000 0 0 0 I: Bus=0019 Vendor=0000 Product=0005 Version=0000 N: Name="Lid Switch" P: Phys=PNP0C0D/button/input0 S: Sysfs=/class/input/input5 U: Uniq= H: Handlers= B: EV=21 B: SW=1 I: Bus=0019 Vendor=0000 Product=0003 Version=0000 N: Name="Sleep Button (CM)" P: Phys=PNP0C0E/button/input0 S: Sysfs=/class/input/input6 U: Uniq= H: Handlers=kbd B: EV=3 B: KEY=4000 0 0 0 0 BTW I haven't a /dev/input/eventX BTW under KDE 3.5.7 the Kmilo plugin recognize correctly both actions, pops up a windows called "Brightness" having a bar which is increased respectively decreased accordingly to the pressed keys. and finally : I compiled the evdev module (CONFIG_INPUT_EVDEV=m) and run your program w/o success. No Fn key event was logged, other key instead created events. ok, I tested the behaviour with current git kernel 2.6.24-rc2 and the reported issue went away, therefor I would close the bug. Only one thing I'd like to mention : Even under 2.6.24-rc2 there was no event at event0 after I pressed <Fn>+<F?>. >Even under 2.6.24-rc2 there was no event at event0 after I pressed <Fn>+<F?>.
It's thinkpad_acpi rather than keyboard driver that handles the hotkey events.
So input events should be sent by thinkpad_acpi driver.
Make sure the thinkpad_acpi(CONFIG_THINKPAD_ACPI) is loaded and listen to that event channel it takes. :)
