Tweaking

Desktop effects

Create a new file /etc/modprobe.d/blacklist-nvidia.conf with the following content. 

blacklist nouveau
blacklist nvidia

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

apt-get purge 'nvidia*'

Suspend

Suspend doesn’t work out of the box because of a problem with the USB buses. A work around that has been reported working for some is 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): 

BUSES="0000:00:1a.0 0000:00:1d.0"
BUSES3="0000:07:00.0"

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
        # Switch USB 3.0 buses off
        for bus in $BUSES3; do
            echo -n $bus | tee /sys/bus/pci/drivers/xhci_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
        # Switch USB 3.0 buses back on
        for bus in $BUSES3; do
            echo -n $bus | tee /sys/bus/pci/drivers/xhci_hcd/bind
        done
        ;;
esac

Make it executable: 

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

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

Reported minor issues

  • 'Jumpy' two-finger scroll
