Creating a basic xorg.conf file and adding these lines works around the
problem:
Section "Monitor"
Identifier "HDMI1"
Option "Ignore" "True"
EndSection
Section "Monitor"
Identifier "HDMI2"
Option "Ignore" "True"
EndSection
Section "Monitor"
Identifier "DP1"
Option "Ignore" "True"
EndSection
Section "Monitor"
Identifier "DP2"
Option "Ignore" "True"
EndSection
Section "Monitor"
Identifier "DP3"
Option "Ignore" "True"
EndSection
