==Installation==
 +
See [[Install from USB stick]]. There is out-of-the-box support for the wired and wireless NICs. There are no special instructions for installation. For an in-depth guide on the installation see the [[Beginners' guide]].
  
=Introduction=
+
==Xorg==
First, feel free to help out!
+
===DPI Settings===
 +
In general the autodetected DPI does not fit the smaller resolution very well at all. A good comfortable setting would be 96dpi or 75dpi if you like your fonts really small. An easy way to set your DPI would be to add this to the end of your xserverrc (located in {{ic|/etc/X11/xinit/}}).
  
Secondly this wiki page assumes you are using kernel 2.6.29 or greater
+
exec /usr/bin/X -nolisten tcp '''-dpi 96'''
  
The stock 2.6.29 kernel works just fine. There is no need for customized eeepc kernel. These customized kernel use to contain patches to allow the hotkeys and what not work. All of these features have been merged into the kernel.
+
See also [[Xorg#Display size and DPI]].
  
=Installation=
+
===Graphic Performance===
Use the 2009.02 installation usb image: [[Install_from_USB_stick]]. There is support for the NIC card and wireless. There are no special instructions for installation. For an indepth guide on the installation see the [[Beginners_Guide]]
+
  
=Xorg=
+
See [[Intel]] for more information.
This example uses hotplugging. Make sure that you have hal installed and started. Also, don't forget to add hal to your system startup!
+
  
==Sample Config==
+
According to the Intel driver documentation, X-Video Motion Compensation or "XvMC" is not enabled by default. Enabling this option can greatly reduce CPU utilization when playing back MPEG-2 video. To enable this option, two things need to be done; first, add this to the device section of your {{ic|xorg.conf}}:
Here is a basic xorg config file. Using xrandr you can switch between the lcd + external display.

==Powersaving==
==acpi-eeepc-generic==
+
===laptop-mode-tools===
#Check out the svn: <pre>svn checkout http://acpi-eeepc-generic.googlecode.com/svn/branches/0.9</pre>
+
I got the best powersaving from a combination of [[Laptop Mode Tools]].
#cd to 0.9 directory
+
#run makepkg
+
#Install Package <pre>pacman -U acpi-eeepc-generic-0.9b-1-any.pkg.tar.gz</pre>
+
  
Do not use the package from AUR until version 0.9 is released. The 0.8.2 version does not have support for the 1000HE.
+
Use laptop-mode to control all power saving features. Enable bluetooth.conf, cpufreq.conf, hal-polling.conf, intel-hda-powersave.conf, usb-autosuspend.conf, and lcd-brightness.conf.
 +
* For lcd-brightness, use the following options. Adjust your max/min brightness as suits you. The maximums are located in the same directory as the control file.
 +
BATT_BRIGHTNESS_COMMAND="echo 3"
 +
LM_AC_BRIGHTNESS_COMMAND="echo 15"
 +
NOLM_AC_BRIGHTNESS_COMMAND="echo 15"
 +
BRIGHTNESS_OUTPUT="/sys/devices/virtual/backlight/eeepc/brightness"
 +
* The intel-hda-powersave has a side-effect. Short sounds such as IM notifications may not come through, or will be messed up as it starts playing the sound before the sound card wakes up.
  
==Sleep==
+
====Super Hybrid Engine====
Use '''pm-suspend''' instead of the script in acpi-eeepc-generic.
+
The eeepc "Super Hybrid Engine" as it is known under Windows has a significant effect on powersaving. This underclocks the FSB for powersave/overclocks for performance and can be controlled via {{ic|/sys/devices/platform/eeepc/cpufv}} which is provided by the {{Ic|eeepc_laptop}} module. The following is a laptop-mode configuration for it that controls it automatically.
The acpi-eeepc-generic suspend script will cause the system to re-suspend when being waked up or when exiting X!
+
  
==cpufrequtils==

<pre>
To scale the cpu and possibly save a bit of power you will want to setup cpufrequitls

===Wireless===
 +
The rt2860sta wireless has pretty good powersaving, but it is a tradeoff between throughput<->power usage. Minimum power usage gives a pretty low throughput of ~11KB/s when I would normally get >1MB/s.
 +
  iwpriv ra0 set PSMode=MAX_PSP
 +
* MAX_PSP - maximum power saving
 +
* CAM - seems to be normal
 +
* FAST_PSP - ? untested, probably a medium value.

Installation

See Install from USB stick. There is out-of-the-box support for the wired and wireless NICs. There are no special instructions for installation. For an in-depth guide on the installation see the Beginners' guide.

Xorg

DPI Settings

In general the autodetected DPI does not fit the smaller resolution very well at all. A good comfortable setting would be 96dpi or 75dpi if you like your fonts really small. An easy way to set your DPI would be to add this to the end of your xserverrc (located in /etc/X11/xinit/).

exec /usr/bin/X -nolisten tcp -dpi 96

See also Xorg#Display size and DPI.

Graphic Performance

See Intel for more information.

According to the Intel driver documentation, X-Video Motion Compensation or "XvMC" is not enabled by default. Enabling this option can greatly reduce CPU utilization when playing back MPEG-2 video. To enable this option, two things need to be done; first, add this to the device section of your xorg.conf:

Option "XvMC" "true"

Lastly, create a configuration file to tell the X server where the XvMC library is:

echo /usr/lib/libIntelXvMC.so > /etc/X11/XvMCConfig

Touchpad

See Touchpad Synaptics

xrandr

For a nice GUI tool, try lxrandr; it is very simple to use!

Switch to External Monitor:

xrandr --output LVDS --off --output VGA --auto

Switch back to eeepc's LCD:

xrandr --output LVDS --auto --output VGA --off

Powersaving

laptop-mode-tools

I got the best powersaving from a combination of Laptop Mode Tools.

Use laptop-mode to control all power saving features. Enable bluetooth.conf, cpufreq.conf, hal-polling.conf, intel-hda-powersave.conf, usb-autosuspend.conf, and lcd-brightness.conf.

  • For lcd-brightness, use the following options. Adjust your max/min brightness as suits you. The maximums are located in the same directory as the control file.
BATT_BRIGHTNESS_COMMAND="echo 3"
LM_AC_BRIGHTNESS_COMMAND="echo 15"
NOLM_AC_BRIGHTNESS_COMMAND="echo 15"
BRIGHTNESS_OUTPUT="/sys/devices/virtual/backlight/eeepc/brightness"
  • The intel-hda-powersave has a side-effect. Short sounds such as IM notifications may not come through, or will be messed up as it starts playing the sound before the sound card wakes up.

Super Hybrid Engine

The eeepc "Super Hybrid Engine" as it is known under Windows has a significant effect on powersaving. This underclocks the FSB for powersave/overclocks for performance and can be controlled via /sys/devices/platform/eeepc/cpufv which is provided by the eeepc_laptop module. The following is a laptop-mode configuration for it that controls it automatically.

#! /bin/sh

if [ x$SUPERHE_CONTROL_FILE = x ]; then
    SUPERHE_CONTROL_FILE=/sys/devices/platform/eeepc/cpufv
fi

if [ x$CONTROL_SUPERHE = x1 ]; then
    if [ $ON_AC -eq 1 ]; then
        if [ $ACTIVATE -eq 1 ]; then
            SUPERHE_VALUE="$LM_AC_SUPERHE"
        else
            SUPERHE_VALUE="$NOLM_AC_SUPERHE"
        fi
    else
        SUPERHE_VALUE="$BATT_SUPERHE"
    fi
    echo $SUPERHE_VALUE > $SUPERHE_CONTROL_FILE
fi
#
# Configuration file for Laptop Mode Tools module eee-superhe
#
# For more information, consult the laptop-mode.conf(8) manual page.
#

# Control FSB speed. Requires eeepc_laptop kernel module loaded.
CONTROL_SUPERHE=1
 
# 2 is powersave
# 1 is normal
# 0 is performance

BATT_SUPERHE=2
LM_AC_SUPERHE=0
NOLM_AC_SUPERHE=0

# If your system has the control file located at another point
# configure it here
# SUPERHE_CONTROL_FILE=

Wireless

The rt2860sta wireless has pretty good powersaving, but it is a tradeoff between throughput<->power usage. Minimum power usage gives a pretty low throughput of ~11KB/s when I would normally get >1MB/s.

iwpriv ra0 set PSMode=MAX_PSP
  • MAX_PSP - maximum power saving
  • CAM - seems to be normal
  • FAST_PSP - ? untested, probably a medium value.

acpi-eeepc-generic

Install the acpi-eeepc-generic package from AUR. You must install version 0.9 or greater, as previous versions do not have support for the 1000HE.

Sleep

If you want to use pm-suspend from pm-utils with acpi-eeepc-generic, edit /etc/conf.d/acpi-eeepc-generic.conf to comment out the line

#SUSPEND2RAM_COMMANDS=("echo -n \"mem\" > /sys/power/state") # Simple suspend

and uncomment the line

SUSPEND2RAM_COMMANDS=("pm-suspend") # Use pm-utils

cpufrequtils

To scale the CPU and possibly save a bit of power, you will want to set up CPU Frequency Scaling. For this you will be using the acpi-cpufreq kernel module. Note that if you have already configured Laptop Mode Tools to set governors, frequencies, etc then you do not need to bother with loading the cpufreq daemon.

WiFi

WiFi should work out of the box with the stock kernel. However, if you do have trouble, you can try switching to the rt2860sta module provided by the rt2860 package. If you use the AUR package, you may need to blacklist the rt2800lib and rt2800pci modules.

Bluetooth

To turn the bluetooth radio on/off:

 # enable
