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.
