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 don't 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. For AMD catalyst drivers, please use the catalyst and catalyst-utils packages from the AUR.

Audio

After running alsaconf the graphics card was the default audio output, so I had to create /etc/asound.conf 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 ##

  case "$2" in
    MUTE) amixer set Master toggle ;;

  case "$2" in
    VOLDN) amixer set Master 2%- ;;
  esac
  ;;

  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.
