How to solve main problems if you install Ubuntu 11.10 on Ausu N53SV.

Hardware issues

System boot problem:

Sometimes my computer freeze on boot, there is white screen and computer doesn’t response. These modifications partially helped me, but sometime the problem is still happen. I welcome any ideas.

• Edit grub configuration

  sudo nano /etc/default/grub

• Modify lines

  #GRUB_HIDDEN_TIMEOUT=0
  GRUB_DEFAULT=0
  #GRUB_HIDDEN_TIMEOUT=0
  #GRUB_HIDDEN_TIMEOUT_QUIET=true
  GRUB_TIMEOUT=2
  GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=192MB video=vesa:off gfxpayload=text"

• Save file and apply new grub configuration

  sudo update-grub

• Reboot your computer

nVidia Optimus:

• Add a PPA containing recent nVidia drivers:

  sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

• Add the Stable Bumblebee Releases PPA:

  sudo add-apt-repository ppa:bumblebee/stable

• Update apt-get repositories information

  sudo apt-get update

• Install Bumblebee and nVidia drivers

  sudo apt-get install bumblebee bumblebee-nvidia

• The installer does not update the initial ramdisk to save time. Run the next command once after the first installation of Bumblebee:

  sudo update-initramfs -u

• If you have 32-bit applications like Wine, you will need extra libraries:

  sudo apt-get install virtualgl-libs:i386

• Allow yourself to use Bumblebee by adding yourself to the ‘bumblebee’ group. (replace $USER by your username)

  sudo usermod -a -G bumblebee $USER

• Reboot or re-login to apply the group changes

If you’d like to run a program on the intel card now:

firefox &

If you’d like to run a program on the nvidia card now, use the optirun program:

optirun firefox &

Blue LED indicates Intel graphics card in use, white LED indicates active nVidia card.

• Create a script under /etc/pm/sleep.d/:

  sudo nano /etc/pm/sleep.d/20_custom-ehci_hcd 

• Insert the following code into the file you have just created:

  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
  

• Save file and close the editor
• Add executable permission:

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