General Tweaks
Auto adjust screen brightness on AC Power or Battery
Since Gnome 3 there is no GUI way to specify a different backlight level for battery and AC but you can use the following script from
askubuntu user chris to set screen brightness via dbus on a power managment event.
gksudo gedit /etc/pm/power.d/00-brightness
Paste the following in the editor window and replace user=chris with user=<your username>
export DISPLAY=:0
user=chris
bat_bright=50
ac_bright=90
. /home/$user/.dbus/session-bus/*
case $1 in
true)
echo "Enable screen power saving"
sudo -u $user -g $user dbus-send --session --print-reply --dest="org.gnome.SettingsDaemon" \
/org/gnome/SettingsDaemon/Power org.gnome.SettingsDaemon.Power.Screen.SetPercentage uint32:$bat_bright
;;
false)
echo "Disable screen power saving"
sudo -u $user -g $user dbus-send --session --print-reply --dest="org.gnome.SettingsDaemon" \
/org/gnome/SettingsDaemon/Power org.gnome.SettingsDaemon.Power.Screen.SetPercentage uint32:$ac_bright
;;
esac
Save the file, close the editor window and make it executeable
sudo chmod 755 /etc/pm/power.d/00-brightness
Enable Hibernation (Suspend to disk)
Hibernation (also called 'Deep Sleep' or 'Suspend to Disk') has been disabled by default in Ubuntu 12.04 because it did not work on all models. Our Eee PC's can hibernate without a problem, so you can safely re-enable it with:
gksudo gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
add the following to the file:
[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
After the next Login, "Hibernate" should show up in the power menu.
Adjust plymouth (bootsplash) theme:
gksudo gedit /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.script
set a black background by adjusting these 2 lines to:
Window.SetBackgroundTopColor (0.0, 0.00, 0.0); # Nice colour on top of the screen fading to
Window.SetBackgroundBottomColor (0.0, 0.00, 0.0); # an equally nice colour on the bottom
Power Management & Hotkeys Support
The great Application
Jupiter provides Power Management (Asus 'Super Hybrid Engine') and maps the EeePC's Hotkeys to Functions. A must - have!

Editable Autostart-Applications
According to
this bugreport the ubuntu devs think it's a good idea to hide the Startup Applications from the Users. Well, I don't. To re-populate gnome-session-properties run:
cd /etc/xdg/autostart/
sudo sed --in-place 's/NoDisplay=true/NoDisplay=false/g' *.desktop
Reduce Swap Usage
The 'swappiness' parameter (scale goes from 0 = don't swap at all to 100 = aggressively swap) controls the tendency of the kernel to move processes out of physical memory and onto the swap disk.
9 If you own the 2 Gig RAM Model you can safely reduce the swappiness to get better response times.
gksudo gedit /etc/sysctl.conf
add the line
vm.swappiness=10
Set Gdebi as default file handler for debian packages
If you prefer a simpler & faster gui way to install deb packages give
gdebi a try
sudo apt-get install gdebigedit ~/.local/share/applications/mimeapps.list
If the file mimeapps.list does not exist, set a custom open with application for a filetype of your choice. This will populate the mimeapps.list file. Now open it and add / edit the line "
application/x-deb" in the [Default Applications] section to
application/x-deb=gdebi.desktop
Make applications Autostart only in the selected Desktop Enviroment
Autostart Applications place a .desktop file in ~/.config/autostart or in /etc/xdg/autostart. If an application should only start in Gnome, open the correspondig .desktop file and add
to make the Application start in Gnome & Unity:
to make the application start on Gnome-Fallback only add:
AutostartCondition=GNOME3 if-session gnome-fallback
NOTE: This also works for Launcher on the Desktop. If you want a custom Application Launcher to show in Unity only, add the 'OnlyShowIn' line to the corresponding .desktop file
Nautilus Image Converter Script
sudo apt-get install nautilus-image-converter imagemagick
Optional: Move your logs and temporary files to RAM
NOTE: This tweak is only useful if you own the 2 Gig RAM model of the EeePC 1015PN and you system runs good. DO NOT USE IT with 1 GB RAM!
The following tweak will help to save some energy by writing temporary & log files to RAM and reducing disk writes
6
sudo -sservice rsyslog stop
echo "tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0" >>/etc/fstab
echo "tmpfs /var/log tmpfs defaults,noatime,mode=1777 0 0" >>/etc/fstab
mv /tmp /tmp2
mkdir /tmp
mv /var/log /var/log2
mkdir /var/log
mount -a
rsync -av /tmp2/ /tmp
rsync -av /var/log2/ /var/log
rm -rf /tmp2
rm -rf /var/log2
service rsyslog start
What those commands do
First we stop the syslog daemon, then we edit FSTAB and add the new mountpoints. Next we move the /tmp & /var/log folders to a new temporary location and create new folders. Now we apply the changes to fstab, move the old files to their new locations and clean the temp folders. Finally we restart the syslog service.
NOTE: Please bear in mind that moving those logs and temp directories to memory will cause the contents to be lost when you restart. You can still manually copy them to another directory before reboot with
rsync -av /var/log/* ~/saved_logfiles
Tweak Firefox
To change the FF cache directory open Firefox, and in the address bar type 'about:config'. Click through the warning message. Now Right click anywhere in the parameter listing and select New -> String. Set the preference name to 'browser.cache.disk.parent_directory' (without the ticks) and set the value to '/tmp/ff-cache' (again without the ticks).
Tweak Chromium
Chromium has command-line options to control memory management. Available options are --memory-model=<high| medium|low> Setting it to high makes chromium never release memory. Medium makes it reduce its working set of the memory when switching tabs, and low makes it reduce its working set when switching tabs and when the browser is not actively being used. In my experience, running chromium with --memory-model=low can improve performance.
Another useful command line switch is --disk-cache-dir. If you have moved your /tmp to Ram, set chromium to use this Location for Cache.
Add your desired Chromium statup option to the /etc/chromium-browser/default file:
gksu gedit /etc/chromium-browser/default
Change the line after ' # Options to pass to chromium-browser ' to read:
CHROMIUM_FLAGS="--memory-model=low --disk-cache-dir=/tmp"
Tweak Google Chrome:
Add your desired Chrome statup option to the /opt/google/chrome/google-chrome.dektop file:
gksu gedit /opt/google/chrome/google-chrome.desktop
Replace the Exec Line with:
Exec=/opt/google/chrome/google-chrome --memory-model=low --disk-cache-dir=/tmp %U
Advanced Power Saving Tips
Only use these if you know what you are doing ;)
- Activate wireless power saving mode with 500ms (broadcom proprietary wlan driver only)
sudo iwconfig wlan0 power timeout 500ms
- Reduce wireless adapter power to 5 (broadcom proprietary wlan driver only)
sudo iwconfig wlan0 txpower 5
- Power saving options for intel sound module
sudo sh -c 'echo Y > /sys/module/snd_hda_intel/parameters/power_save_controller'
sudo sh -c 'echo 1 > /sys/module/snd_hda_intel/parameters/power_save'
sudo sh -c 'for i in /sys/bus/usb/devices/*/power/level; do echo auto > $i; done'
sudo sh -c 'for i in /sys/bus/usb/devices/*/power/autosuspend; do echo 1 > $i; done'
sudo sh -c 'for i in /sys/bus/pci/devices/*/power/control; do echo auto > $i; done'
- Set SATA link Power management to min_power
sudo sh -c 'for i in /sys/class/scsi_host/host*/link_power_management_policy; do echo min_power > $i; done'
How can I configure Unity?
see here:
http://askubuntu.com/questions/29553/how-can-i-configure-unity/101415#101415A tweak tool for unity that allows you to export and import a set of settings for Unity is
unsettings
sudo add-apt-repository ppa:diesch/testing
sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install unsettings
I have adjusted the unity configuration to fit our 1024x600 screen. If you want to use my config download the
netbook.unsettings file to your Computer.
Open Unsettings, click on the "Load Settings from File" button, select netbook.unsettings you downloaded and click on the "Apply Settings" button.
How can I reset the unity configuration?
To remove any launchers you've added run:
To reset all of the launcher options run:
Unity Dodge autohide & minimize window on click
This is a customized unity build that auto-hides the left application launcher panel if an application is on fullscreen. On our small Laptop screen we need every mm so this is perfect for our devices. Also a click on the panel icon of a running app will minimize the window.

Audio and Video Player
For Audio I use the fast and lightweight
Decibel Audio Player and a good video Player is
Smplayer. Install them with:
sudo apt-get install decibel-audio-player
- Install
mplayer2 (the playback engine Smplayer uses)
sudo add-apt-repository ppa:motumedia/mplayer-daily
sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install mplayer2 libx264 libblueray1
since this is a daily build ppa you can disable it after the install and update the mplayer package on demmand.
sudo add-apt-repository -r ppa:motumedia/mplayer-daily
- Install Smplayer (faq) from the developers (rvm) ppa
sudo add-apt-repository ppa:rvm/smplayer
sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install smplayer
Configure Smplayer for vdpau (nvidia GPU with HDMI Audio out) and xv (intel GPU with Cinch connector / Laptop speakers Audio out) simultaneously:
Options - Preferences - General - Video Tab
=> Output Driver: User defined... vdpau:deint=42:denoise=1,xv,
=> untick the 'Enable post processing by default' checkbox
Options - Preferences - General - Audio Tab
=> Output Driver: User defined... alsa:device=hw=1.7,pulse,
=> Checkbox 'Global Volume'
=> Checkbox 'Use Software Volume Control'
Options - Preferences - Preformance
=> Checkbox 'Allow Frame Drop'
=> Loop Filter: 'Skip only on HD Videos'
Options - Interface
=> Autoresize: 'Never'
Options - Advanced - Options for Mplayer
=> Extra options for mplayer:
-vc ffmpeg12vdpau,ffh264vdpau,ffwmv3vdpau,ffvc1vdpau,
You can set Audio Sync during playback via the + and - Keys on the Keyboard. But sync is usually ok here and HD content (incl. 1080p) plays very
smooth with vdpau (nvidia GPU).

Graphics Card Switching
As noted above both VGA Chips can be used in Exclusive Modes (intel or nvidia) or in a Dual GPU Mode (intel and nvidia) . The Nvidia Chip is useful for high performance stuff (like Gaming, HDTV, ect) but draws a lot of power from the battery. For basic operation I find the Intel GMA 3150 sufficient.
In dual Gpu Mode ( "Optimus" Mode) both chips are available via lspci. The "Hot-Switching" between both chips is work-in-progress and requires some mayor xorg rework, so it will still take some time. As a temporary workaround you might want to try bumblebee. Be aware that this is very hackish so only do this if you are confident you can fix a broken system. 13
The scripts in the provided Package allow you to set the desired VGA Mode for the next boot via a simple GUI.
Install the Nvidia Binary Driver:
sudo apt-get install nvidia-current nvidia-settings
Vdpau Benchmarks with Nvidia Binary Driver
Optional: If you want to stay on the bleeding edge nVidia drivers enable the x-swat ppa:
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install nvidia-current nvidia-settings
Optional: The nouveau modues are disabled by the postinstall script of the acpitools deb package. If you do not intend to use the deb package provided below blacklist them with:
sudo -s
echo options nouveau modeset=0 | tee -a /etc/modprobe.d/nouveau-kms.conf
update-initramfs -u
Install the VGA - Switching Helper scripts
This PPA hos
ts the acpi call & bbswitch kernel module and the current Version of the VGA Helper scripts for the
EeePC 1015PN for ubuntu oneiric and precise (i386 & x86_64). After the install go to "Applications -> System Tools -> Vga Selector" and choose the desired Vga mode for the next boot.
Make sure that your system is fully updated and you are running the latest installed kernel.
sudo add-apt-repository ppa:mtron/eee1015pn
sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install eee1015pn-acpitools build-essential debhelper module-assistant lm-sensors
Now run the Sensors auto-detection
sudo sensors-detect
Just press enter at each question to use the default answer. Only the last question (add the modules to /etc/modules) should be answered with 'yes'.
After the configuration completed reboot.
Test if it works:
sudo display-settings status

- Optimus mode: Auto Disable nvidia chip on boot
display-settings Command Line Options
The script has more options when called from a terminal with
sudo display-settings <option>
where
<option> is one of the following:
- auto: In this mode the script will look for a .vga-selector file written by the GUI script and executes the acpi_call for the desired option (Intel,Nvidia or Optimus mode). It will also prepare the xorg configuration and glx libraries for the next boot. If the script can't find any .vga-selector file it will use the selected default GPU.
- status: This will output current VGA Mode. E.g "Active GPU: Intel GMA3150 on PCI 00:02.0"
- fix: This will automatically fix the display configuration depending on the available VGA Chips that can be accessed via lspci. It will also update the nvidia glx libraries after the install of a new(er) nvidia driver version.
- reboot-intel: activate intel for next boot and prepare xorg conffiles for intel. The nvidia chip won't be visible via lspci and is disabled so it won't draw any power from the battery.
- reboot-nvidia: activate nvidia for next boot and prepare xorg conffiles for nvidia. The intel chip won't be visible via lspci.
- reboot-optimus: activate both gpu's for next boot and prepare xorg conffiles for intel.
NOTE: For GPU Hot-Switching you need to install
bumblebee
- nv-off: For Optimus Mode only! This will disable the nvidia chip to save some energy.
- nv-on: For Optimus Mode only! This will enable the nvidia chip.
- config-intel: This option is for emergency purposes. If xorg can't start and you are dropped to a text shell after boot fix your configuration by running "display-settings status". If you get "Active GPU: Intel GMA3150" run display-settings again with this Option and restart gdm.
- config-nvidia: This option is for emergency purposes. If xorg can't start and you are dropped to a text shell after boot fix your configuration by running "display-settings status". If you get "Active GPU: Nvidia GT218" run display-settings again with this Option and restart gdm.
For further Documentation on the VGA modes and acpi_calls for the Eee 1015PN see the
hybrid-graphics-linux mailing list.

TODO: update for debian
Alternative: Set the VGA Mode manually
If you can't - or do not want - to use the helper scripts read on.
- Manually install the acpi_call kernel module from the linux-hybrid-graphics project:

cd acpi_call
make
sudo insmod acpi_call.ko
check with "dmesg | grep acpi_call" that the module was loaded successfully.
- Set the VGA Mode for the next boot:

ldconfig
NOTE:
- Replace libglx.so.280.13 with the Version of your installed nvidia driver
Now reboot.
- Mode 3 : Optimus Mode with Intel GMA 3150 and Nvidia GT218 (Next Gen Ion)
This mode keeps both VGA Chips active, but currently only the intel chip can be used in this mode. Work is going on to make "Hot-Switching" possible, so keep your fingers crossed To enable Optimus mode for next boot, switch to root (sudo -s) and run
echo "\OSGS 0x03" > /proc/acpi/call
and proceed with the Steps outlined in Mode 1 above.
To save power after the reboot in Optimus mode, turn off the nvidia chip via another acpi_call (acpi_call.ko module needs to be loaded again):
echo "\_SB.PCI0.P0P4.DGPU.DOFF" > /proc/acpi/call
This will give you additional 2 hours of battery life.
