I just installed Fedora all seemed to go well till after a few minutes of use. I was logged in and started to view a few things on my desktop when my screen went blank and I received a message "Out of scan range".
I'm able to Ctrl-Alt-F1 and get to a terminal session and each time I return to the graphical view a few seconds to minutes the screen goes blank.
I searched and found were this could be a config problem in my /etc/X11/xorg.cong file and it was recommended that I insure the Vertical and Horizontal values were correct. I didn't see these values in the file.
I would like to learn more about the values and setting in this file could someone help by letting me know were I could find such information.
By the way the hardware that is having the problem is:
ATI Radeon X300 video and SDM-X72 Sony display.
