working xinerama configuration with 8 monitors (slow performance)

I also created and tested a Xinerama/one Display configuration.

Here I also have to enable the the monitors manually via xrandr after x
start-up - also don't know why:

DISPLAY=:0.0 xrandr --output DisplayPort-1-4 --auto --right-of DisplayPort-3
DISPLAY=:0.0 xrandr --output DisplayPort-1-5 --auto --right-of DisplayPort-1-4
DISPLAY=:0.0 xrandr --output DisplayPort-1-6 --auto --right-of DisplayPort-1-5
DISPLAY=:0.0 xrandr --output DisplayPort-1-7 --auto --right-of DisplayPort-1-6

RESULT:
Display :0.0
Screen 0: minimum 320 x 200, current 14400 x 1200, maximum 16384 x 16384
DisplayPort-0 connected primary 1920x1200+0+0 (normal left inverted right x
axis y axis) 518mm x 324mm
DisplayPort-1 connected 1920x1200+1920+0 (normal left inverted right x axis y
axis) 518mm x 324mm
DisplayPort-2 connected 1920x1200+3840+0 (normal left inverted right x axis y
axis) 518mm x 324mm
DisplayPort-3 connected 1920x1200+5760+0 (normal left inverted right x axis y
axis) 518mm x 324mm
DisplayPort-1-4 connected 1680x1050+7680+0 (normal left inverted right x axis y
axis) 474mm x 296mm
DisplayPort-1-5 connected 1680x1050+9360+0 (normal left inverted right x axis y
axis) 474mm x 296mm
DisplayPort-1-6 connected 1680x1050+11040+0 (normal left inverted right x axis
y axis) 474mm x 296mm
DisplayPort-1-7 connected 1680x1050+12720+0 (normal left inverted right x axis
y axis) 474mm x 296mm

It is working - slow - but it is working. :-)
