## Summary

Things that "just work":

- Wlan (`ath9k` is part of the kernel; some use `brcmsmac`)
- Ethernet
- Graphics (with `kms` and `dri2`, using the xf86-video-ati driver)
- Webcam (using `v4l`)
- Suspend-to-RAM (after installing acpid)
- Cardreader (but keucr is in staging, thus taints the kernel. PyroPeter experienced crashes while he inserted or removed sd cards)
- Bluetooth (after installing bluez)
- CPU Frequency Scaling (Use `acpi_cpufreq` since linux 3.7)
- TouchPad (support multi-touch after installing xf86-input-synaptics)
- Video Acceleration (either open source driver (xf86-video-ati) or ATI/AMD's propretary driver(catalyst) work)

    /etc/modprobe.d/eeepc1015b.conf

    # supposed to help against following msg in dmesg:
    # SP5100 TCO timer: mmio address 0xbafe00 already in use
    blacklist sp5100_tco

    # if you do not need the sd-card reader you may want to blacklist
    # keucr. it is in staging, thus taints the kernel
    blacklist keucr

    # if you find "ACPI: resource piix4_smbus [io 0x0b00-0x0b07]
    # conflicts with ACPI region SMRG [io 0xb00-0xb0f]"
    # in /var/log/messages.log ,try to uncomment the following line
    # blacklist i2c_piix4

## Graphics

The open source drivers will work adequately.

## Audio

After running alsaconf the graphics card was the default audio output, so `/etc/asound.conf` must be created with the following contents:

    defaults.ctl.card 1
    defaults.pcm.card 1
    defaults.timer.card 1

Volume function key for alsa:

    /etc/acpi/handler.sh

    ......
            open)
                #echo "LID opend!">/dev/tty5
                ;;
        esac
        ;;
    ## volume control key ##
    button/mute)
      case "$2" in
        MUTE) amixer set Master toggle ;;
      esac
      ;;
    button/volumedown)
      case "$2" in
        VOLDN) amixer set Master 2%- ;;
      esac
      ;;
    button/volumeup)
      case "$2" in
        VOLUP) amixer set Master 2%+ ;;
      esac
      ;;
    ## volume control key end ##
    *)
      logger "ACPI group/action underfined: $1 /$2"
      ;;
    esac

## Powersaving

When system is idle, ATI/AMD's propretary driver(catalyst) saves 2.5W than xf86-video-ati.
