Ubuntu

For this one I wanted a minimal maintenance stuff for basic laptop operations so I chose the latest Ubuntu at the moment: Lucid Lynx.
Actually they have a version special for netbooks, installable from a USB stick, cool:

Ubuntu Netbook 10.04

The only thing is that I wanted to only replace the 2 NTFS partitions and keep the last 2 partitions for now.
First time I tried I used the partition tool from Ubuntu installer but if it succeeded completing the install, after reboot it appeared that the partition table didn't contain refs to the root partition, ouch! So the new partition table was never written to the disk.
I rebooted on a good old FCCU liveCD v12 and changed the partition table the way I wanted then I did again the Ubuntu install, this time without troubles.

Now eeepc-laptop kernel module will be properly loaded

Super Hybrid Engine

This requires eeepc-laptop module

Jupiter is taking care of multiple power saving settings including the eee SHE if you install also jupiter-support-eee
See http://www.webupd8.org/2010/06/jupiter-take-advantage-of-asus-super.html

aptitude install libnotify-bin acpi

Get packages jupiter & jupiter-support-eee from here

Hotkeys

The package presented above (jupiter) takes care of the extra FN buttons.
There is also packages eee-applet & eeepc-acpi-scripts
Or eeepc-control

Touchpad

Bugs

At reboot I sometimes encountered the following bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/572279

Firmware upgrade

It has v1102, since there were a couple of new versions:

1401 Update brightness table
1301 Improve Wifi performance
1301 Update EC firmware
1203 Fix there is no "safely remove hardware" icon in windows 7 when plug in SD card.

So let's try to install v1401

- EEE family / EEE PC / 1005HA / Linux
- BIOS 1401
Unzip archive
Rename file 1005HA-ASUS-1401.ROM into 1005HA.ROM and move it to a USB stick (my 6Gb USB HD wasn't detected I had to use a real 1Gb USB Flash)
Reboot on the USB by pressing ALT-F2 while rebooting
Flash is done automatically
Remove USB stick & reboot
