HaiyueLin, as per your https://launchpadlibrarian.net/146067857/BootDmesg.txt :
[    0.126413] mtrr: your CPUs had inconsistent variable MTRR settings
[    0.126414] mtrr: probably your BIOS does not setup all CPUs.
...
[    0.147453] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored

Hence, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (2.23). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

Title:
  [Acer Aspire v3-771g] System boots into a black screen in EFI mode,
  but desktop loads normally in legacy mode

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a new pc portable acer v3-771g with Win 8 in EFI mode. I have
  tried Ubuntu 12.04.2 and 13.04.  If I don't use the nomodeset code in
  EFI mode, the system boots into a black screen and to tty1 only (no
  desktop) with nomodeset.

  I have tried also Fedora 18 and Opensuse 12.3 and the problem is the
  same except that Opensuse boots in EFI mode with the nomodeset
  parameter.

  WORKAROUND: In Raring, change the BIOS to boot in Legacy mode.
