Howto: Enable ACPI Hotkeys in Ubuntu 10.04 on Eee PC
I had some kind of trouble when I just installed Ubuntu 10.04 (Lucid Lynx) on my Eee PC 1005HA-H. The new Ubuntu comes with the upgraded Bootloader GRUB 2.0. In this short tutorial I will tell you how to enable ACPI Hotkeys on your Eee PC or mabye other Netbooks from different manufacturers like Toshiba.
First, you have to know, that there’s a kernel module called “eeepc laptop” which can’t be loaded when GRUB isn’t configured for it. You have to tell the system which kind of ACPI model will be needed.
- Open /etc/default/grub with your favourite editor
- Go to GRUB_CMDLINE_LINUX_DEFAULT and add the following param: acpi_osi=Linux.
The config line should look this way:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
Then save the config file and execute the command “update-grub”
to update grub.
FYI: There looks like to be a bug that your pppoe-connection won’t work
and your eth0 NIC won’t be available after you edited the GRUB-Config.

Ikkerus,
Thanks for this article. I’m using Lucid on a Toshiba Satellite Pro L300. I had exactly the same issue as reported in this article – inability to use the function keys to alter brightness (the brightness applet didn’t work either). Your suggestion worked. The reference to the launchpad article was also helpful to get an idea of what’s going on.

Hey Joe,
Thank you for your reply to this article. I didn’t see it until today because I’m not gonna get noticed about it. It’s now updated that this will maybe help for other Netbooks, too.
Thanks

Excellent solution, it was simply and worked out inmediatly! I have a Toshiba L500.
Hello there! Quick question that’s entirely off topic. Do you know how to make your site mobile friendly? My weblog looks weird when viewing from my iphone 4. I’m trying to find a template or plugin that might be able to resolve this issue. If you have any recommendations, please share. Appreciate it!
When I try to type sudo gedit/etc/default/grub it replied command not found.
Did you find other way?
Hi rahmadi,
there’s a typing mistake in your command. Please try the following:
sudo gedit /etc/default/grub
Please let me know if there’s anything else I can do for you.

I did not try anything to make my blog mobile friendly. But I’ll let you know when I get rid of something regarding this.
