working multi-head configuration with 8 monitors
I am not sure, but I think these entry fixed the issue more or less:
Section "Device"
Option "ZaphodHeads" "DisplayPort-X"
EndSection
Also new entries are:
Section "Module"
Load "dri"
Load "extmod"
EndSection
Section "DRI"
Mode 0666
EndSection
Section "Device"
Option "AccelMethod" "glamor"
Option "DRI3" "True"
Option "TearFree" "True"
EndSection
I also have to enable the the monitors manually via xrandr after x start-up -
don't know why:
DISPLAY=:0.4 xrandr --output DisplayPort-1-4 --auto
DISPLAY=:0.5 xrandr --output DisplayPort-1-5 --auto
DISPLAY=:0.6 xrandr --output DisplayPort-1-6 --auto
DISPLAY=:0.7 xrandr --output DisplayPort-1-7 --auto</pre>
