View Full Version : [ubuntu] ATI dual head setup reverts to 'mirror mode' when secondary monitor is turned off

I have been getting this issue with more and more frequency lately and it is driving me insane.

I have a radeon 4850 setup to run in dual head mode and for the most part it works fine. The issue is whenever I turn off both of my screens for any extended period of time when I return I find that it has reverted back into mirror mode and I end up having to restart X to get it back to normal.

I can post my xorg.conf if desired. Any ideas on this?
