Display and input settings
If not already installed, you need xorg and xf86-video-intel to have X working, and also drivers for keyboard and touchpad:
# pacman -S xorg-server xf86-video-intel xf86-input-evdev xf86-input-synaptics
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 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 config file to tell the X server where the XvMC library is:
echo /usr/lib/libIntelXvMC.so > /etc/X11/XvMCConfig
To set the keybord layout and other options, edit or create the file
/etc/X11/xorg.conf.d/keyboard.conf, and add the following:
Section "InputClass" Identifier "Keyboard defaults" MatchIsKeyboard "yes" Option "XkbLayout" "us" Option "XkbModel" "asus_laptop" Option "XkbOptions" "terminate:ctrl_alt_bksp" EndSection
This gives you a US layout, more layouts can be found at
/usr/share/X11/xkb/rules/base.lst. Other options, like using ctrl-alt-backspace to kill the X-server can also be setup here.
Comment out the touchpad section of
/etc/X11/xorg.conf.d/10-evdev.conf, and edit
/etc/X11/xorg.d/10-synaptics.conf to your liking. This example gives you two finger scroll
Section "InputClass" Identifier "touchpad catchall" Driver "synaptics" MatchIsTouchpad "on" Option "VertTwoFingerScroll" "true" Option "EmulateTwoFingerMinZ" "40" Option "EmulateTwoFingerMinW" "5" EndSection
For more information, see Touchpad Synaptics and the synaptics man file.
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 and ACPI
Start off your powersaving adventures by installing Powertop. This is basically a program to see how much power stuff is using, but it also gives you tips on what to change.
# pacman -S powertop
A good starting point is to disable the hardware you do not plan on using. Reboot and enter the BIOS by pressing F2. Disable for example the card reader, camera, ethernet but only if you do not need them of course.
According to Powertop the 1005HA uses around 7-10 Watts on maximum powersave (using Laptop mode tools and cpufreq and the above hardware disabled, using Wifi and writing this). Idle around 5-6 W. Please report how to get it lower!
Laptop mode is a nice and easy way to setup most of the availiable power saving options on the 1005HA. These include spinning down the hard drive and adjusting the power saving modes of the harddrive and CPU, as well as autosuspending of the USB-ports and screen brightness etc. It provides a great centralized configuration file as well as separate configuration files for the various power saving modules managed by Laptop mode tools.
Installation and setup
Install the package with
# pacman -S laptop-mode-tools
The main configuration file is /etc/laptop-mode/laptop-mode.conf but there are more configuration files located in the directory /etc/laptop-mode/conf.d/ Be sure to read them and set them up accordingly.
Note the option in laptop-mode.conf to automatically start many of the other modules.
1005HA specific options for a few of the modules below (there are many more):
For lcd-brightness, edit the file /etc/laptop-mode/conf.d/lcd-brightness.conf and adjust it as suits you. The darkest is 0 and brightest 15, this is a suggested setup:
BATT_BRIGHTNESS_COMMAND="echo 1" LM_AC_BRIGHTNESS_COMMAND="echo 15" NOLM_AC_BRIGHTNESS_COMMAND="echo 15" BRIGHTNESS_OUTPUT="/proc/acpi/video/VGA/LCDD/brightness"
The eeepc "Super Hybrid Engine" as it's 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 module eeepc_laptop. It is included in the laptop-mode-tools package, and is activated and configured in the file /etc/laptop-mode/conf.d/eee-superhe.conf See also this forum thread.
As of the relase of kernel 2.6.32 the needed module eeepc_laptop doesn't work, to get this working you will need to add the following to the kernel line in the GRUB config (eg. /boot/grub/menu.lst):
The CPU frequency can be controlled by the file cpufreq.conf provided by laptop mode tools. A good value is ”T2” (75% speed) when on battery and ”minimum” (full speed) when on AC. However, using the cpufrequtils package (see below) is normally a better option, as the ondemand option automatically changes between the specified modes depending on system load.
Tip: make use of the option to disable the suspending of some USB hardware (eg. 3g modems) by using lsusb to get the ID and then insert it in the configuration file.
CPU frequency scaling
To get the hotkeys working (fn+F1 etc, touchpad lock, powerbutton shutdown, Super hybrid engine toggle), install the acpi-eeepc-generic package from AUR. Configuration is done in the file /etc/conf.d/acpi-eeepc-generic.conf.
To enable the toggling of the Wifi by pressing fn+f2, edit the acpi-eeepc-generic config file and change
Sound volume hotkeys
In order to get the hotkeys for muting and raising and lowering of the sound volume, edit /etc/conf.d/acpi-eeepc-generic.conf and replace the lines:
COMMANDS_MUTE=("alsa_toggle_mute") COMMANDS_VOLUME_DOWN=("alsa_set_volume 5%-") COMMANDS_VOLUME_UP=("alsa_set_volume 5%+")
COMMANDS_MUTE=("@amixer set Master toggle") COMMANDS_VOLUME_DOWN=("@amixer set Master 10%-") COMMANDS_VOLUME_UP=("@amixer set Master 10%+")
Note that the value 10% can be any value you prefer, see the man page of amixer.
If you have problems with the script provided in acpi-eeepc-generic, try pm-suspend instead.
To substitute pm-suspend for the acpi sleep script, edit /etc/conf.d/acpi-eeepc-generic.conf and comment out the line that reads:
Replace it with:
Create the /etc/X11/xorg.conf file and add the following to it to enable Intel's framebuffer compression, which according to Lesswats.org is supposed to save quite some power.
Section "Device" Identifier "Builtin Default intel Device 0" Driver "intel" Option "FramebufferCompression" "on" Option "AccelMethod" "EXA" Option "Tiling" "on" EndSection
Works with the stock 2.6.32 kernel, if you use an earlier kernel you might need to install the driver from the AUR.
WiFi works out of the box with the stock kernel (tested with 2.6.30 and 2.6.32).
To enable/disable the camera:
# enable echo 1 > /sys/devices/platform/eeepc/camera # disable echo 0 > /sys/devices/platform/eeepc/camera
If you really want camera to be disabled, take a look in devices section of BIOS.
Make sure that the module
uvcvideo is loaded
To record video and take photos, you may use cheese or the wxcam package.
To simply test the camera, you may use
mplayer -fps 15 tv://
The webcam works with Skype.
The microphone works out of the box, it's just a matter of configuration. Run:
Press <F4> to go to the 'Capture' section. Navigate to the 'Capture' item using the right and left arrow keys and make sure 'LR Capture' appears. If it doesn't, press <Space>. The 'Capture' and 'Digital' levels are a trade-off between gain and static. I recommend setting to 70 and 75 (using the up and down arrow keys), respectivelly, but you can ajust this to your liking. Exit alsamixer pressing <ESC> and test it:
$ arecord /tmp/record.wav
Say something close enough to the microphone and hit <Ctrl+C> to stop recording. Play it with:
$ aplay /tmp/record.wav
If everything went well, save your settings (as root):
# alsactl store
