How is your monitor connected to your PC (HDMI, DVI, DP, VGA)? I also had
such a problem some months ago after I connected my monitor via DP. For 
some reason sometimes the video output of my graphics card was only sent 
to its DVI port and not to the DP. 
However after a update of xorg and its components this error was gone.
