Title:
  AMD Radeon HD 8400 [1002:9830] Garbled display with open-source driver
  on Trusty

Status in HWE Next Project:
  New
Status in xserver-xorg-video-ati package in Ubuntu:
  Confirmed

Bug description:
  CID: 201305-13643 HP Pavilion 15

  This system will suffer from the low-graphic mode issue (bug 1301839) after boot.
  But this problem has been fixed, running "sudo apt-get dist-upgrade" from tty1 could solve this problem.

  However, after upgraded, the display will be garbled.
  Install the proprietary could solve it.
  I will mark this bug as a blocker since the desktop is totally unusable.

  Steps:
  1. Install 14.04 + update (3.13.0-29) from tty1, boot to desktop.
  (with  xserver-xorg-video-ati version 1:7.3.0-1ubuntu3.1)

  Expected result:
  * Display should work after upgraded.

  Actual result:
  * Display grabled, screenshot attached.

  [1002:6660] Works fine after upgrade on other systems, so I think it's
  the problem for [1002:9830]
