Known Errors:

Touchpad and Keyboard Aren't working The solution is to add i8042.nomux=1 i8042.reset to the end of the kernel line of the grub menu config at

/boot/grub/menu.lst

Example:

# (0) Arch Linux

title  Arch Linux

root   (hd0,2)

kernel /boot/vmlinuz-linux root=/dev/sda3 ro i8042.nomux=1 i8042.reset nomodeset quiet vga=0

initrd /boot/initramfs-linux.img


Graphics: This model has the a6-3400m apu with an integrated radeon HD 6520g. This is problematic during the livecd install. If you do not hit tab at the arch boot screen and add "radeon.modeset=0" to the kernel line, you will end up with a black screen. After install, use the proprietary Catalyst driver, as the opensource one has multiple problems.

Audio: Alsa does not work. The central speaker, PCM, won't show up under alsa until pulseaudio is installed. Pulseaudio works perfectly with the audio system, even enabling mic input without a hitch.

Webcam: It is a v4l2 webcam, works perfectly.

Hibernate/Suspend: There is a problem in which trying to sleep will cause a black screen, followed by flickers which persist until an acpi poweroff. Upon booting, the laptop will not make it to the bios until the battery and charger are removed. The fix for this is documented at

[http://thecodecentral.com/2011/01/18/fix-ubuntu-10-10-suspendhibernate-not-working-bug ]

Step 1: Create a file at /etc/pm/sleep.d/20_custom-ehci_hcd, with the following code:


  1. !/bin/sh
  2. inspired by http://art.ubuntuforums.org/showpost.php?p=9744970&postcount=19

VERSION=1.1 DEV_LIST=/tmp/usb-dev-list DRIVERS_DIR=/sys/bus/pci/drivers DRIVERS="ehci xhci" # ehci_hcd, xhci_hcd HEX="xdigit:" MAX_BIND_ATTEMPTS=2 BIND_WAIT=0.1

unbindDev() {

 echo -n > $DEV_LIST 2>/dev/null
 for driver in $DRIVERS; do
   DDIR=$DRIVERS_DIR/${driver}_hcd
   for dev in `ls $DDIR 2>/dev/null | egrep "^$HEX+:$HEX+:$HEX"`; do
     echo -n "$dev" > $DDIR/unbind
     echo "$driver $dev" >> $DEV_LIST
   done
 done

}

bindDev() {

 if [ -s $DEV_LIST ]; then
   while read driver dev; do
     DDIR=$DRIVERS_DIR/${driver}_hcd
     while [ $((MAX_BIND_ATTEMPTS)) -gt 0 ]; do
         echo -n "$dev" > $DDIR/bind
         if [ ! -L "$DDIR/$dev" ]; then
           sleep $BIND_WAIT
         else
           break
         fi
         MAX_BIND_ATTEMPTS=$((MAX_BIND_ATTEMPTS-1))
     done  
   done < $DEV_LIST
 fi
 rm $DEV_LIST 2>/dev/null

}

case "$1" in

 hibernate|suspend) unbindDev;;
 resume|thaw)       bindDev;;

esac


Step 2: Make this file executable with this command:

sudo chmod 755 /etc/pm/sleep.d/20_custom-ehci_hcd

Step 3: Enjoy. The screen still flickers, but the laptop goes into proper sleep.
