Is the live DVD image of Ubuntu on official site of Ubuntu up to date? Because I could not install Ubuntu 14.04 from live CD because of black screen.

This is most probably due to your graphic card. You could try the following, boot up using the live cd and at the Grub menu press "e" to edit the first entry.

At the end of the Linux kernel entry line add nomodeset and press F10 key. This should boot up Ubuntu with less optimized graphics.

  • That sounds more like a backlight issue then. Try this fix.

  • I tried to work with this fix but it is only for openSUSE. I don't have any option to add boot options.

  • You need to add the options acpi_backlight=vendor acpi_osi=Linux to the Linux kernel line as shown in the screenshots for Ubuntu, put them instead of nomodeset.

  • This is how my screen looks like when booting from USB: postimg.org/image/e66w6jbvv and this is how it looks like after pressing "e": postimg.org/image/nincrhb3r. Where should I put that option line.
