Comment 9 for bug 918769

Hi Jerome,

Upstream seems quiet. It may be possible to work around this though. Try switching off some of the extraneous outputs and see if that eliminates the blinking. So, try an xorg.conf like this:

Section "Device"
        Identifier "Configured Video Device"
EndSection

Section "Monitor"
        Identifier "Configured Monitor"
        Identifier "HDMI1"
        Option "Ignore" "True"
EndSection

Section "Monitor"
        Identifier "Configured Monitor"
        Identifier "HDMI2"
        Option "Ignore" "True"
EndSection

Section "Monitor"
        Identifier "Configured Monitor"
        Identifier "HDMI3"
        Option "Ignore" "True"
EndSection

Section "Monitor"
        Identifier "Configured Monitor"
        Identifier "DP1"
        Option "Ignore" "True"
EndSection

Section "Monitor"
        Identifier "Configured Monitor"
        Identifier "DP2"
        Option "Ignore" "True"
EndSection

Section "Monitor"
        Identifier "Configured Monitor"
        Identifier "eDP1"
        Option "Ignore" "True"
EndSection

Section "Screen"
        Identifier "Default Screen"
        Monitor "Configured Monitor"
        Device "Configured Video Device"
EndSection

Pardon any typos, this is written off the top of my head.

Assuming that works and eliminates the blinking, the next step is to isolate the minimum output(s) that need disabled. One by one comment out the Monitor sections and restart X. If X works without blinking, leave the section commented out. If it blinks, then re-enable it by uncommenting the section, and move on to the next output. Let us know what you find.
