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

  • http://support.asus.com/download/download.aspx
    • 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

Ubuntu

Install

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.

I advise to keep at least the EFI partition as it's an 8Mb primary partition used by the BIOS for its "Boot Booster".
In case you already deleted it, simply recreate it with fdisk: 8Mb, type "ef". On reboot, hit F2, and re-enable boot booster in the BIOS.
Mine is at end of the 250Gb HDD: 

   Device Boot      Start         End      Blocks   Id  System
/dev/sda4           30400       30401       16064+  ef  EFI (FAT-12/16/32)

Out-of-the-Box

Working:

  • Suspend-to-RAM
  • Suspend-to-Disk (hibernate)
  • Webcam
  • VGA output
  • Ethernet
  • Wi-Fi
  • Audio playback
  • CPU freq scaling 1/1.33/1.66GHz, ondemand
  • sdcard reader
  • Silverkey disable touchpad
  • Hotkeys: suspend, Wi-Fi on/off, disable touchpad, brightness up/down, volume off/up/down
  • Bluetooth, it detected a W300i phone and I could use the phone as remote control OOB, could use it to access Internet as well apparently
  • My 3G USB key (Vodaphone K3565 = Huawei E160)

Not working?:

  • multi-touchpad. See below the paragraph about Touchpad
  • audio mic. See below the paragraph about Microphone
  • Hotkeys: backlight on/off (not clear, it worked at the beginning, anyway it's barely usable without any backlight... Once Jupiter is used it seems it's used as VGAOFF)
  • Hotkeys: hotkey display toggle, hotkey display resize, taskmanager, super-hybrid-engine. See below how to use them with eeepc-laptop & Jupiter

Powersave Tuning

eeepc-laptop

eeepc-laptop module gives access to the eee hotkeys & eee Super Hybrid Engine for better powersafe control

Install driver: 

$ modinfo eeepc-laptop
filename:       /lib/modules/2.6.32-23-generic/kernel/drivers/platform/x86/eeepc-laptop.ko
license:        GPL

vermagic:       2.6.32-23-generic SMP mod_unload modversions 586 
parm:           hotplug_disabled:Disable hotplug for wireless device. If your laptop need that, please report to acpi4asus-user@lists.sourceforge.net. (bool)

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

In /var/log/syslog

If you run X11, you should use xrandr instead.

Camera:

1 = on
0 = off

SDCard reader: 

/sys/devices/platform/eeepc/cardr:
1 = on
0 = off

CPU clock configuration: 

/sys/devices/platform/eeepc/cpufv:
0 = Super Performance Mode
1 = High Performance Mode
2 = Power Saving Mode

Reading this file will show the raw hexadecimal value which is defined as follow: 

| 8 bit | 8 bit |
    |       `---- Current mode
    `------------ Availables modes

For example, 0x301 means: mode 1 selected, 3 available modes.

Jupiter

Jupiter is taking care of multiple power saving settings including the eee SHE & GMA950 overclocking if you install also jupiter-support-eee
See http://www.webupd8.org/2010/06/jupiter-take-advantage-of-asus-super.html To install it, there are a few pre-requisite: 

aptitude install libnotify-bin acpi

Get .deb packages jupiter & jupiter-support-eee from here & install them

It takes also care of the extra FN buttons (there is also packages eee-applet & eeepc-acpi-scripts or eeepc-control if you prefer not to use Jupiter)

Applet will start at reboot, otherwise you can already start it manually by calling "jupiter.exe" (oups, C#...)
Hovering applet displays CPU temperature.

Issue: very slow at displaying messages when pressing several times / several buttons in a short amount of time.

Support:

powertop & greedy applications

powertop permits to spot easily which applications are wakening the CPU dozen of times per second and/or are writing files to the disk, preventing spin down. 

aptitude install powertop

Maybe you can simply disable applications at startup but as I didn't use them anyway I removed them completely:

ubuntuone-* was causing 16% of the wakeups
How to remove it? 

killall ubuntuone-login ubuntuone-preferences ubuntuone-syncdaemon
rm -rf ~/.local/share/ubuntuone
rm -rf ~/.cache/ubuntuone
rm -rf ~/.config/ubuntuone
rm -rf ~/Ubuntu\ One/ # unless you've valuable data here, be careful!
sudo apt-get purge ubuntuone-client* python-ubuntuone-storage*

It removed rhythmbox-ubuntuone-music-store python-ubuntuone libubuntuone-1.0-1 ubuntuone-client-gnome ubuntuone-client python-ubuntuone-client python-ubuntuone-storageprotocol

Desktopcouch is also quite active, actually it's used amongst others by evolution, gwibber, ubuntu-one,... so let's remove gwibber 

killall gwibber-service
apt-get purge gwibber*

It removed gwibber gwibber-service

and all CouchDB 

pkill -f couch
apt-get purge couch*

It removed python-desktopcouch-records python-desktopcouch desktopcouch couchdb-bin python-couchdb

other monitoring commands

We just saw powertop, here are some other handy commands which can help debugging activities on the HDD & spindown matters.
You can skip completely this section if you don't plan to get your hands dirty.

Smartmontools: 

aptitude install -R smartmontools

by default the daemon will not run, we just want to have smartctl available 

smartctl -A /dev/sda|grep ^193
193 Load_Cycle_Count        0x0032   100   100   000    Old_age   Always       -       352

so here 352 spinoff cycles over the HDD lifetime.

Hdparm:
Will be used by laptop-mode-tools for powersaving, see next chapter.
To watch if the drive is spinning or not: 

watch hdparm -C /dev/sda

To spin down immediately (for debug only. You want it to be automated, don't you?) 

hdparm -y /dev/sda

Ngflushd:
A kind of super noflushd, but more oriented towards server & supports journaling fs
You can install the .deb but make sure to edit /etc/default/ngflushd to disable the daemon startup, we'll use it here only for statistics collection
Example if you want to try ngflushd to actually spin down the HDD, not to be used simultaneously with laptop-mode!
Note that in this example I disabled partitions remount because it failed with "ngflushd: Remount error: /dev/sda7: Invalid argument" 

ngflushd -t1 -w50 -j6 -l500 -a

Watching the results after two hours: 

ngflushd -c status
Daemon state: IDLE     Disks: 0/1 (up/dn)  Uptime: 1:54 (h:mm)
Disk: /dev/sda       S  mounts: 3  down: 68%   cycles: 23 (484.5 day)

OK, now here we'll start the daemon in foreground, then switch it to PAUSED mode so it will collect data but won't act on the HDD. It's a nice way to watch laptop-mode efficiency. 

ngflushd -vv -d -a

From another terminal, send a suspend command to the daemon to switch it to PAUSED mode: 

ngflushd -c suspend

Back to the daemon window, you can observe in realtime when external event spins down the HDD: 

ngflushd: Daemon state: PAUSED   Disks: 1/0 (up/dn)  Uptime: 0:00 (h:mm)
ngflushd: External spindown: /dev/sda
ngflushd: Normal spinup: /dev/sda: after 0:00 (h:mm)
etc

blktrace:
Watching which application writes to the drive, preventing it to spin down: 

aptitude install blktrace
blktrace -d /dev/sda -o - | blkparse -i -

The output is buffered and will be flushed when CTRL-C, a pity.
The output is quite hard to understand, see man page

iostat:
Only global IO usage on HDD: 

aptitude install sysstat
iostat -p sda 2

Some more details about HDD spinning down in this thread

laptop-mode-tools

aptitude install -R laptop-mode-tools

=> accept to remove pm-utils-powersave-policy
pm-utils-powersave-policy was doing two things:

  • increase dirty_writeback to one minute
  • Power down HDA controller with corresponding Sigmatel/IDT codec after 10 idle seconds

laptop-mode-tools is doing the same, but we've to enable the Intel HDA powersave mode manually

Default config of the main laptop-mode-tools in /etc/laptop-mode/laptop-mode.conf was ok for me, I just wanted to enable a few extra modules, see below

Intel HDA power saving settings:
Modify /etc/laptop-mode/conf.d/intel-hda-powersave.conf 

CONTROL_INTEL_HDA_POWER=1

FYI powertop suggested automatically this powersave setting, which corresponds to 

echo 1 > /sys/module/snd_hda_intel/parameters/power_save

Intel SATA power management settings:
Modify /etc/laptop-mode/conf.d/intel-sata-powermgmt.conf 

CONTROL_INTEL_SATA_POWER=1

FYI powertop suggested automatically this powersave setting, which corresponds to 

echo min_power > /sys/class/scsi_host/host0/link_power_management_policy

Note that it seems min_power is always set even when on AC

USB autosuspend settings:
Modify /etc/laptop-mode/conf.d/usb-autosuspend.conf 

CONTROL_USB_AUTOSUSPEND=1

FYI powertop suggested automatically this powersave setting

Note that laptop-mode could also take care of CPUfreq & eee SHE but we're already using Jupiter for that.

relatime

ngflushd sets relatime when remounting ext3/ext4 but laptop-mode-tools doesn't do it so we've to set it ourselves in /etc/fstab: 

UUID=xxx /               ext4    errors=remount-ro,relatime 0       1
UUID=xxx /home           ext4    defaults,relatime          0       2

See here what is relatime: to summarize, relatime is a good compromise between atime (most expensive) and noatime (least expensive)

Power consumption measurements

Using powertop, you can get an idea of the power consumption of the various elements.
Getting it right is always a bit tricky as you've to make sure there is no other active elements than the ones you want to measure, especially check that the HDD is spin down (hdparm -C /dev/sda).
Measurements are not per sub-system but the total power consumption, then only you can approximate what's the diff when feature is on/off, and for basis X=(LCD_off, WiFi_off) you've to find it from A=(LCD_on, WiFi_off), B=(LCD_off,WiFi_on) and C=(LCD_on,WiFi_on): X=A-(C-B)

How I did measurements:

  • HDD standby (spinning down), better to run it at start of each non HDD test...
hdparm -y /dev/sda
  • LCD backlight off (be sure it's not just a black screen!)
DISPLAY=:0.0 xset dpms force off
  • HDD read once per second to keep it spinning
for i in /usr/bin/*; do sleep 1; cat $i >/dev/null; done
  • HDD read continuously
dd if=/dev/sda of=/dev/null
  • HDD read/write continuously
dd if=/dev/sda of=/tmp/foo
  • Camera active
cheese
  • Keeping CPU busy (!logical dualcore)
while :;do :;done& while :;do :;done
  • Forcing CPU to 1GHz

Running in ConfigA (4.6W, with Wi-Fi) for 8.5 hours:

  • -> battery at 38% capacity, remains 5.2h (4.6*(8.5+5.2)=63Wh)
  • expected total autonomy: 13.7h

So I got the following approximations:

  • Basis (laptop-mode, CPU 1GHz idle, HDD standby, Wi-Fi disabled, BT disabled, LCD off, camera disabled, cardr disabled)
    • 4.1W / 4.8W
      • different results on different days... CPU fan on/off??

Tuning ONGOING

powertop proposed some more power saving settings:

Wireless card powersave mode: 

iwconfig wlan0 power timeout 500ms

Disable camera USB 

echo 0 >  /sys/devices/platform/eeepc/camera

Disable SDCard reader 

echo 0 >  /sys/devices/platform/eeepc/cardr

could be done via /etc/laptop-mode scripts or scripts via Jupiter

laptop-mode:

? auto-hibernate required or is it already the case??

Touchpad

aptitude install gpointing-device-settings

& enable circular scrolling (System / Pointing Devices)

For multi-touch I'm not sure how to proceed. Lucid Lynx doesn't use hal anymore.
See

Microphone

Microphone does not work out of the box.
From here:
Install the pulse audio tools 

aptitude install paman pavucontrol pavumeter padevchooser

Sound & Video / PulseAudio Volume Control / Input Devices tab:
Unmute audio
Unlock channels
Set front left channel to 100% and the front right channel to 0%.
