This question may be marked as duplicate but questions I've found alike in askubuntu stackoverflow ubuntuforum can not solve this problem or give me an answer.

The model of my laptop is Acer V7-481 which comes with an i3-3227U CPU and NO graphic card.

When I was installing ubuntu 12.04 for the first time, the laptop booted up in a black screen

The only solution to this is to add a boot parameter nomodeset or something to disable the KMS.

Other solutions I found are useless, including acpi related and adjust the backlight using shortcuts etc.

Now, my laptop can only boot with nomodeset but I don't think the integrated graphic card is functioning normally.

  1. I cannot connect to a second monitor via HDMI and Display Port
  2. unity is running in 2d mode
  3. can't use 3d hardware acceleration

Why not Ubuntu 14.04? – TuKsn May 14 '14 at 10:16
@Xubu-Tur No I didn't. Should I do that? How? – ericls May 14 '14 at 11:08
Perhaps it will run better. – TuKsn May 14 '14 at 13:09
