Po-Hsu Lin, as per http://www.dell.com/support/home/us/en/19/product-
support/product/inspiron-3135/drivers an update to your computer's buggy
and outdated BIOS is available (A02). 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 provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

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

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible, and the
information above is provided, then please mark this report Status
Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.

Title:
  AMD Radeon HD 8210[1002:9834] Brightness cannnot be adjusted without
  fglrx driver

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  CID: 201308-14057 Dell Inspiron 3135

  Brightness cannot be adjusted if the proprietary fglrx video driver is not installed.
  Module "radeon" cannot be found in lsmod, it seems that this graphic chip is not supported

  Steps:
  1. Install 12.04.3, and boot to desktop.
  2. Try to adjust screen brightness with hotkey
  3. Try to adjust screen brightness in "Brightness and Lock"

  Expected results:
  1. Brightness could be adjusted by the hokey
  2. Brightness could be adjusted in "Brightness and Lock"

  Actual Results:
  1. Hotkey event was correctly captured, brightness indicator level will change accordingly, but the brightness won't be altered.
  2. Brightness cannot be adjusted in "Brightness and Lock" as well

  Update to 3.8.0-33 still not helping with this.

  However, acpi_backlight=vendor in grub can make it work.
  So as the proprietary fglrx driver.
