If vainfo can't load the driver, then Chromium HW acceleration will
definitely not work.

Title:
  Chromium DEV - new update disable all GPU optons on FGLRX driver

Status in chromium-browser package in Ubuntu:
  New

Bug description:
  Hi,

  From last time I use Chromium DEV PPA for Ubuntu and all GPU options work fine.
  Now after two or one latest update all GPU options in chrome:gpu is disabled - I have only software mode, not like before hardware accelerated. Only software...

  I try enable it but I can.

  I try log my browser in terminal:

  Also in chrome:gpu I have in log message:

  "Log Messages
  GpuProcessHostUIShim: The GPU process exited with code 256."

  Also look at my graphics feature in chrome:gpu:
