[Bug 556782] Re: [rs690m] [Gateway] Graphics corruption with ati x1200


This bug was NOT ressolved even in Kernel 3.17!

Even with latest Enlighment (E19), I experience text corruption when enabling hardware acceleration in Compositing window.
When switching to Software rendering, there is no issue.

KDE freezes simply after certain period of work if hardware acceleration
is used.

  [rs690m] [Gateway] Graphics corruption with ati x1200

Status in X.org XServer - ATI gfx chipset driver:
  Fix Released
Status in linux package in Ubuntu:

Bug description:
  This bug has been around for a bit over a year now, and has gotten rather long, so this is a brief summary.
  There is a memory corruption issue that affects users of the rs690m, to varying degrees.
  For many most people, it makes the desktop unusable.

  Workaround:   *Note: This is a workaround, not a fix.  It will give you a usable system.
  [Natty]: Regression: This workaround now only provides 2d/software rendering, and one must either:
     * Choose choose the "Ubuntu Classic" session from the GDM Login screen
     * Install the "unity-2d" package.  
  sudo su
  echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf
  Note that this doesn't totally fix the issue, but brings your desktop to a workable state.

  Freedesktop.org has dealt with one bug having to do with graphics corruption on the rs690m.  That bug has been fixed, but the issue of graphics corruption in general has not been resolved.  A new bug has been opened with freedesktop.org to continue pushing through the resolution of this issue.
