Configuration
Video
The xf86-video-ati driver is recommended, read ATI for more information.
Networking
Wireless ethernet driver brcmsmac should automatically load at startup.
This should no longer be needed, but in the past, the modules bcma and acer-wmi caused conflicts and had to be blacklisted.
Setup may be further configured by reading Wireless network configuration.
Audio
Initially, audio does not work, except for beeping. The problem may be corrected by editing /usr/share/alsa/alsa.conf and replacing every instance of card 0 with card 1. (This also works on the AO725-0488.)
As of kernel 3.1, the headphone jack is correctly supported.
For kernel versions < 3.1, a bash script may be used to switch between the internal speakers and headphones. First, install the alsa-tools package.
Next, save the following bash script:
#!/bin/bash
# If needed, change these to the pins of the headphones and speakers, can be found using hda analyzer
pin_headphones="0x19"
pin_speakers="0x1f"
case "$1" in
[Hh]*)
hda-verb /dev/snd/hwC1D0 "${pin_headphones}" \
set_pin_wid 0xc0
hda-verb /dev/snd/hwC1D0 "${pin_speakers}" \
set_pin_wid 0x00
;;
[Ss]*)
hda-verb /dev/snd/hwC1D0 "${pin_headphones}" \
set_pin_wid 0x00
hda-verb /dev/snd/hwC1D0 "${pin_speakers}" \
set_pin_wid 0x40
;;
esac
Run the script as root with h or s as an argument to switch to headphones or speakers. Sometimes the command must be run again if a new audio program is started. (Taken with modifications from this discussion in the forums.)
HDMI Audio issue
The hdmi video display works fine out of box (as of 2014-1-1, using ATI driver), however, HDMI audio does not work. Searching the forum, there is some indication this is due to video driver issue.
Beep on Power Cord Plug-In/Out
To lower the loudness of the beep when the power cord to an acceptable level, open alsamixer ,select the HDA ATI SB sound card using F6 and mute the Beep by using arrow chars and then pressing m
Dual Boot
See Windows and Arch dual boot for general information. Note that this netbook does not come with recovery CDs. If an attempt to set up dual boot goes awry and you cannot boot the machine at all, or cannot boot into Windows, you can restore the original Windows configuration by booting into /dev/sda1, the recovery partition, as if it were an ordinary Windows installation. The recovery program says it will wipe the whole disk but will only wipe the partition on which Windows resides. (You can install grub from the Arch installation media onto a thumbdrive and take it from there.)
