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.

Tuning

eeepc-laptop

sudo vi /etc/default/grub
=> GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
sudo update-grub
reboot

Now eeepc=laptop kernel module will be properly loaded

$ ls /sys/devices/platform/eeepc/
available_cpufv  cpufv_disabled   input/           subsystem/
camera           disp             modalias         uevent
cardr            driver/          power/           
cpufv            hwmon/           rfkill/

Hotkeys

There is also packages eee-applet & eeepc-acpi-scripts but it seems to work without them as FN buttons work well

Touchpad

aptitude install gpointing-device-settings

& enable circular scrolling (System / Pointing Devices)

Additional packages

openssh-server

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

- 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
