How to enable Fn keys on Eee PC 1005HA and 10.04 Lucid Lynx?

[Navyblue]

Fn+F1 = Suspend. Works even before the grub fix.
Fn+F2 = Wireless/Bluetooth Toggle. Works even before the grub fix. However, it seems to toggle WiFi only. In XP it toggles Bluetooth as well. That's not a problem though. No on-screen notification.
Fn+F5 = Decrease Brightness. Works even before the grub fix. Before grub fix, on-screen notification was available. After the grub fix, on-screen notification stopped working.
Fn+F6 = Increase Brightness. Works even before the grub fix. Before grub fix, on-screen notification watills available. After the grub fix, on-screen notification stopped working.
Fn+F8 = Toggle monitor. Works after applying the grub fix. No on-screen notification.
Fn+F9 = ? combo key. Works after applying the grub fix. I remapped this key combo to launch an application.
Fn+F10 = Mute. Works after applying the grub fix. On-screen notification works fine too.
Fn+F11 = Decrease Volume. Works after applying the grub fix. On-screen notifitchcation works fine too.
Fn+F12 = Increase Volume. Works after applying the grub fix. On-screen notification works fine too.

I am Eee PC 1015 PEM, Everything is as described. Except that there is a bug for brighness OSD. At maximum brightness, the OSD isn't at maximum (at about 2/3), however it still take the same 5 notches from minimum to maximum.

On top of that, after adjusting brightness, there will be a drop in brightness when a key is pressed (brightness OSD would appear too). However after adjusting the brightness and another function key is toggled (such as volume), the brightness will drop but will instantly revert (brightness OSD would still briefly appear).

So it's either the volume control or the brightness control.

Hi!

Try these steps.
1) Open terminal and type
Code:

sudo gedit /etc/default/grub


2) enter password
3) add
Code:

acpi_osi=Linux

to
Code:

GRUB_CMDLINE_LINUX_DEFAULT

, so that it will look like:
Code:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

4) save file
5) open terminal again, and type
Code:

sudo update-grub

6) restart the machine
7) use hotkeys

I may have found a solution for others who can't get thier various function keys to work.

Open a terminal and run

xev

now any key you press (or mouse movement0 will send the information into the terminal. If it is a hotkey that is allready set up may get a 'Notify Event' message.

When I did this I found my F3 key with a Fn combo became an XF86TouchpadToggle event.
The next job was to write a custom shell script to turn the touchpad on and off, then use the XF86TouchpadToggle as the property for a new custom shortcut, and set it to see my shell script.


----Extra info just in case the above doesn't work----
It is possible to determine what the key codes for all the key press combinations, you need to skip into a 'proper terminal' (use Ctrl Alt Fn [n=1 to 12 ~] ie a function key)

Login into this 'session' and run the following command

dumpkeys

this command produces a lot of output, so I recomend sending it to a file for easier reading, like the following...

dumpkeys >keyInfo.txt

Now if that file doesn't get you anywhere, you may need this command...

getKeyCodes

again you may want to redirect to a file.

then you can look for the key combo you are interested in.

Alternatively you can run

showkey -a

or

showkey -s

then when you press your key combo you will get the ASCII return codes for them.

I found the xev stuff on the web, but I can't find the link now!
showkey stuff comes from http://rick.vanrein.org/linux/funkey/
and to be able to run dumpkeys and getKeyCodes without errors I figured out from a reply on LinuxQuestions.

I've become a bit of a rarity on these forums over the last year or so, so if you want more info you may find I respond quicker to a pm, but remember to post here also, to help others.
