My machine is a 13" notebook connected to a 22" external monitor. Using AMD CC I set it up so that the notebook screen is my primary monitor and the 22" my secondary.
If I am planning to watch a movie or the like I sometimes switch my notebook screen off by rotating through the available display configurations FN+F3. That works fine but as soon as I restart my PC the dual monitor setup I configured disappears and in its place I get a mirrored setup. Rotating through the configuration option doesn't help.
As a result, each time I turn off either of the screens, I have to reconfigure the dual monitor setup on next system start. That wasn't the case before with Ubuntu Natty.
How can I solve this problem?
Thank you very much in advance.
