cd AX88772B_772A_760_772_178_LINUX_Driver_v4.2.0_Source

make

sudo make install

sudo modprobe asix

That's it. You should be able to connect using a wired connection now.

WLAN

echo "options ath9k nohwcrypt=1" >> /etc/modprobe.d/ath9k.conf

Bluetooth

he bluetooth module is the Atheros AR3012, which requires loading a firmware before it can be used. For now, patching the kernel is required to recognize this module as AR3012 one.

Sensors (temps & fans)

sudo aptitude install lm-sensors
sudo tee -a /etc/modules <<-EOF

Startparameter in Grub

• pcie_aspm=force
  ASPM is not enabled by default, at least not yet. As far as I know this is ongoing work.
  See also: http://www.phoronix.com/scan.php?pag...solution&num=1
• i915.modeset=1
  Is enabled by default, therefore unnecessary. It was only required for older 3.2-rc kernels (rc5 and below, because of a regression which is now fixed).
• i915.i915_enable_rc6=1
  Is enabled by default in the 3.2 kernels if VTd is disabled, but not in 3.1. Significant power usage improvements. Causes problems with VTd enabled.
  See also: http://intellinuxgraphics.org/2011Q4.html
• i915.semaphores=1
  Enabled by default in the 3.2 kernels (only if VTd is disabled). Not enabled in 3.1, causes problems together with VTd, see http://intellinuxgraphics.org/2011Q4.html.
  Edit: will probably get deactivated by default with the final release of Linux 3.2, see https://lkml.org/lkml/2011/12/23/247.
• i915.i915_enable_fbc=1
  Is enabled by default since kernel 3.1, according to http://intellinuxgraphics.org/2011Q4.html.
• i915.lvds_downclock=1
  Based on the quote above posted by nomego and the output of "xrandr", the Zenbook uses eDP (Embedded Display Port) instead of LVDS. So this option has no effect.
• intel_iommu=off
  Alternative to disabling VTd in the BIOS.
• acpi_oci="Linux"
  Only a cosmetical fix, because a line in dmesg (?) recommended it, but no positive or negative effect known.
  This doesn't signify any problem with Ubuntu or with the Linux kernel. What the message indicates is that your BIOS is querying the operating system to see whether or not Linux is running, and Linux is ignoring this query. The reason for this is that often a BIOS will offer a limited feature set to the operating system when it responds that it is Linux. Linux generally supports all the same features as Windows, so Linux developers consider this query to be a bug in the firmware and instead report that the operating system is Windows so that the full set of features for the machine will be available. The message can be safely ignored.
