Hi, I can confirm I have this problem using two AMD cards on a triple monitor setup.
Unity_2d session works and running 'unity --reset' does not render the 3d version of unity and the display results in broken windows. I've attached the log (run_unity_reset.log) Some other info: uname -a Linux ringo 2.6.38-13-generic #55-Ubuntu SMP Tue Jan 24 15:34:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux /usr/lib/nux/unity_support_test -p OpenGL vendor string: ATI Technologies Inc.
