Install Ubuntu 14.04 LTS and dual boot with Windows 8 OEM

The instructions below apply to the installation of Xubuntu 14.04 LTS or Ubuntu 14.04 LTS on a laptop. Where specific instruction is for Lenovo Ideapad Z580 laptop, it is clearly called out.

Important to note before you start.
Xubuntu 14.04 LTS or Ubuntu 14.04 LTS will not dual-boot if you have Windows 8.1 installed. It gives an error with the EFI Boot Manager and appears that Windows 8.1 inhibits it from co-existing as a dual boot. All attempts to fix it failed. Therefore, if you upgraded from Windows 8 OEM to Windows 8.1 when it was offered, please downgrade to Windows 8 OEM version. I did not mind downgrading as my primary Operating System is Linux.

Installation is easy, and you can now follow the instructions below to set up the computer.

  1. Disable guest account logins
  2. Hide list of users on the login screen in Xubuntu/Ubuntu
  3. Enable firewall and test the firewall
  4. Install bumblebee. See how to improve Lenovo battery backup time (this instruction applies to Lenovo Ideapad Z580 laptop with dual graphics (Intel onboard and NVidia Optimus).
  5. Sound with pulseaudio works out of box. No tweaks to be done.
  6. The wireless A/B/G/N networks all work fine, unlike 13.10 where only B/G worked.
  7. Install libdvdcss to play back DVDs.
  8. Install Oracle Java 7
  9. Install libavcodec-extra to get more codecs. This should replace ffmpeg. Open a terminal window and enter the command below:

$ sudo apt-get install libavcodec-extra <enter>
