When ubuntu first installed, the VGA can only support the safe graphic mode and the sound card cannot performs. Luckily there are methods to fix this thing.

1. Insert Ubuntu’s CD (all version, you may use Xubuntu, ubuntu, edubuntu, etc)
2. choose Save graphic mode
3. Install as usual
4. configure APT so to enable repository DVD’s based instasllation , but if you have internet connection, then you don’t have to configure it
5. Install these packages
   1. nvidia-glx-new (VGA)
   2. linux-restricted-modules (sound card)
   3. linux-backports-modules (sound card)
   4. ndiswrapper-common (Atheros wifi)
   5. ndisgtk (Atheros wifi visual)
   6. ndiswrapper-utils-1.9 (dependency
      ndisgtk)
   7. cheese (webcam)
6. Download the driver net5211.inf (the Win XP version not the Vista version) , you can search via Google, the file usually archieved
7. extract the archieved driver
8. Execute this programs

    # ndiswrapper -i net5211.inf
   
   # ndiswrapper -l //make sure the device status is present
   
   # ndiswrapper -m //make sure the latest line shows wlan0 alias
   
   # ndiswrapper -ma
   
   # loadndisdriver

9. Configure sound

   //sound configuration
   
   nano /etc/modprobe.d/alsa-based //add text below on the last line.
   
   options snd-hda-intel model=acer

10. Save/CTRL + X
11. Click System > Administrator > Restricted Driver Manager
12. Enable VGA Driver

PS: There are some laptops that use broadcomm WIFI instead of antheros, so install the driver:
