Public bug reported: Steps to reproduce: hit Alt-F2 and type "xterm" and hit enter and the machine hard-locks.
This only happens when running Unity and using two monitors. Using one monitor with Unity seems to work fine. This is a standard Dell Optiplex 745 with Radeon RV516 (Radeon X1300 Pro) with two DVI outputs. What can I do to narrow this down to Unity or compiz or the radeon driver or Xorg or the kernel?
