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

[Lazy-legs]

Hello,

I've just installed Ubuntu 10.04 Lucid Lynx on my Eee PC 1005HA, and everything seems to work except the Fn keys. The only Fn keys that work out of the box are Brightness Up/Down.

I'm mostly interested in making the Volume Mute/Up/Down keys work, and I'd be grateful for any advice and pointers.

Thank you!

Hi!

Try these steps.
1) Open terminal and type

sudo gedit /etc/default/grub

2) enter password
3) add

acpi_osi=Linux

to

GRUB_CMDLINE_LINUX_DEFAULT

, so that it will look like:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash  acpi_osi=Linux"

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

sudo update-grub

6) restart the machine
7) use hotkeys

I followed those steps on my EEE1005HA, and everything worked. Just have to find a way to ensure dialog boxes come up stating what has been done (e.g. Volume muted).

And I have kind of found a way to enable the messages. So when I click 'FN' & 'Space' it tells me what mode I am using (it's just a bit slow in changing the status). I followed the steps from here, just go to the bit with the title "Super Hybrid Engine, Installing an eeePC tray utility, and getting all hotkeys to work". Also you don't need to install "eeepc-laptop-dkms" according to some other threads which I went through (even if you tried, you'll get some error message).And there's no need to go into the "Finishing off: Final hotkeys" part.

SO yeah, that is basically it. It isn't flawless, but it still works

Adding acpi_osi=Linux did the trick. Thank you so much, kevinp93!

How's the battery consumption compared to karmic koala??

That how-to recommends installing eeepc-tray which is no longer supported or updated. (the project has become "Jupiter" and is available only through sourceforge/download or eeebuntu repositories) It is a great utility but it tends to crap out after key packages are updated - and without updates itself it won't start working again.

For EeePC 1001HA the instructions under #2 worked even better than expected. This means I got WiFi (Fn+F2), keypad enable/disable (Fn+F3), Monitor toggle (Fn+F'8') and all three volume hotkeys (Fn+F10-12). The notifications for volume change work. As a bonus the silver touchpad enable, to the left, works which is even better than under Karmic!

Thanks!

I did this on my 1000HE and everything is working great, except the volume keys. Any ideas?

Hey thanks the the poster who showed how to get the function key working. Could someone explain what exactly happens when you add this to the grub code??
