Comment # 9 on bug 59903 from Michael Lange

an option in my xorg.conf is causing the spam of flip errors in Xorg.0.log


Section "Monitor"
        Identifier      "Denon-AVAMP"
--->    #Option         "Enable"        "true"   <----
        Modeline        "1920x1080" 148.50 1920 2008 2052 2200 1080 1084 1089
1125 +hsync +vsync
EndSection


if "Option Enable true" in the monitor section is commented out, then there is
no log spam
this is a left over to force the hdmi-output to 1920x1080 with the Denon-AVAMP
off ... but i had no luck
