Tweaking

Desktop effects

Create a new file /etc/modprobe.d/blacklist-nvidia.conf with the following content. (You need super user privileges. See here for help. 

blacklist nouveau
blacklist nvidia

Remove nvidia drivers (otherwise it's libGL.so will used by default) 

sudo apt-get purge nvidia

Suspend

Suspend doesn’t work out of the box because of a problem with the USB buses. To fix the problems do the following:

Create a new file /etc/pm/sleep.d/20_custom-asus-u36sd with the following content (you need to have administrative privileges to create it, see here for help.): 

BUSES="0000:00:1a.0 0000:00:1d.0"

case "${1}" in
    hibernate|suspend)
        # Switch USB buses off
        for bus in $BUSES; do
            echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/unbind
        done
        ;;
    resume|thaw)
        # Switch USB buses back on
        for bus in $BUSES; do
            echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/bind
        done
        ;;
esac

Make it executable: 

sudo chmod +x /etc/pm/sleep.d/20_custom-asus-u36sd

This will make the suspending the computer work. Resume, however, will only work if you wait to trigger it around half a minute after suspending was completed. If you resume too early, the computer will do a hard reboot instead.

Fn-keys

Download and install asus-nb-wmi driver (included in 2.6.39, but since Natty runs 2.6.38 need to build it ourselves): 

sudo apt-get install git build-essential
git clone git://git.iksaif.net/acpi4asus-dkms.git
cd acpi4asus-dkms
make
sudo make install
sudo modprobe asus-nb-wmi

Bluetooth

The ath3k module doesn't manage to detect the Bluetooth device, so one need specify it manually. To do so do the following.

Get a super user shell. 

sudo -s -H

Enter the following commands. Ignore the errors from rmmod if any. 

service bluetooth stop
rmmod btusb
rmmod ath3k
modprobe -a ath3k
echo "13d3 3304" > /sys/bus/usb/drivers/ath3k/new_id
modprobe btusb
service bluetooth start
exit

Other issues

Splash

If you want more consistently looking (but possibly slower) boot, try the following.

Create a new file /etc/initramfs-tools/conf.d/splash with the following content. You need super user privileges to create it. See here for help. 

FRAMEBUFFER=y

Then run sudo update-initramfs -u in a terminal.

Disable touchpad while typing

The default version of xserver-xorg-input-synaptics does not include the functionality needed for automatic disabling of the touchpad while typing. If this is something you would like to have, you can follow the instructions below (taken from here). 

mkdir tmpbuild
cd tmpbuild
wget http://david.hardeman.nu/synaptics-suse-patches.tar.bz2
apt-get source xserver-xorg-input-synaptics
cd xserver-xorg-input-synaptics-<version>
cd debian/patches
tar xfvj ../../../synaptics-suse-patches.tar.bz2
ls -1 2*.patch >> series
cd ../..
sudo apt-get build-dep xserver-xorg-input-synaptics
dpkg-buildpackage -us -uc -rfakeroot
sudo dpkg -i ../xserver-xorg-input-synaptics_<version>_<arch>.deb

Change <version> and <arch> depending on the current version available and what architecture you are running on.

After you restarted X the option "Mouse Preferences - Touchpad - Disable touchpad while typing" should work.
