Title:
  screen becomes garbled and system freezes

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Screen either becomes garbled or goes grey/white or multicoloured
  vertical stripes associated with complete system freeze that requires
  holding down the power button down until system powers off.  When the
  screen becomes garbled the mouse pointer is often still visible on top
  of the garbled image.

  The frequency and cuase of the freezes varies but when using firefox
  opening a new tab often induces it.

  I have experienced this under 11.10 64 bit install using both a
  standard setup and after trying the xorg-edgers ppa.  I have also
  repoduced the problem using a Mandriva 2011 live cd.  I dual boot the
  machine with Windows XP and that works without issue.

  My laptop is a Compaq NX6125 with a ATI Radeon Xpress 200M graphics card which uses 128Mb of system memory.  I am also using the default radeon driver.
