Caution: I am learning linux with arch and my Eee PC. So my solutions may be not the best.

HDMI

Video

You have to change the video driver. If the HDMI cable is plugged in on boot it is enabled automatically. If it is plugged in after boot you can use xrandr to enable the second monitor:

# xrandr --output DVI-0 --auto

Audio

You need to now the number of your sound card and the the number of HDMI device:

aplay -l
 **** Liste der Hardware-Geräte (PLAYBACK) ****
Karte 0: Intel [HDA Intel], Gerät 0: ALC269VB Analog [ALC269VB Analog]
  Sub-Geräte: 1/1
  Sub-Gerät #0: subdevice #0
Karte 0: Intel [HDA Intel], Gerät 3: HDMI 0 [HDMI 0]
  Sub-Geräte: 1/1
  Sub-Gerät #0: subdevice #0

In /usr/shared/alsa/alsa.conf search the lines

default.pcm.card 0
default.pcm.device 0

If you change the numbers to your card and device (in my case card is 0 and device is 3) and reboot the audio output switches to HDMI. (I am looking for a way, that is more dynamic --> maybe this)

Screen Brightness

acpi

Setting brightness in /sys/class/backlight/acpi_video0/ with the scripts for acpid change the values of the files brightness and actual_brightness but do not have any effect on current screen brightness.

Set the following as kernel parameters in your bootloader

acpi_osi=Linux acpi_backlight=vendor

To make this permant...

FN Keys

Now there is a folder eeepc-wmi in /sys/class/backlight and the scripts need to be updated

/etc/acpi/actions/bl_up.sh
  #!/bin/sh
  bl_device=/sys/class/backlight/eeepc-wmi/brightness
  echo $(($(cat $bl_device)+1)) >$bl_device
/etc/acpi/actions/bl_down.sh
  #!/bin/sh
  bl_device=/sys/class/backlight/eeepc-wmi/brightness
  echo $(($(cat $bl_device)-1)) >$bl_device

The scripts change the screen brightness everytime I run them. Unfortunately the acpi events for brightnessup and brightnessdown are not available anymore although the brightnessup key sets brightness to maximum and the brightnessdown key sets the brightness to max_brightness-1 :( (do not now where this happens) --> this may help

AC plug / unplug

/etc/acpi/handler.sh
 ..
 ac_adapter)
        case "$2" in
            ACPI0003:00)
                case "$4" in
                    00000000)
                        logger 'AC unpluged'
                        echo $(($(cat /sys/class/backlight/eeepc-wmi/max_brightness)/2)) > /sys/class/backlight/eeepc-wmi/brightness
			;;
                    00000001)
                        logger 'AC pluged'
                        echo $(($(cat /sys/class/backlight/eeepc-wmi/max_brightness)-1)) > /sys/class/backlight/eeepc-wmi/brightness
			;;
                esac
                ;;
            *)
                logger "AC Adapter ACPI action undefined: $2"
		;;
        esac
        ;;
