screen layout KDE vs. expected

SUMMARY

I need xrandr to add a mode to my monitor (broken DDC data).
xrandr sets the display layout correctly
KDE pushes the main monitor to (previous_x;0).

```
#!/bin/bash
modeline_1680="1680x1050_60.00  146.25  1680 1784 1960 2240  1050 1053 1059
1089 -hsync +vsync"
# modeline_1680="`cvt 1680 1050 60|sed -e '1d;s/^Modeline //;s/"//g'`"

xrandr --newmode $modeline_1680
xrandr --addmode DVI-I-0 1680x1050_60.00

XRANDR=(xrandr --output DisplayPort-2 --mode 1920x1080 --pos 3600x0 --rotate
left\
       --output DVI-I-0 --primary --mode 1680x1050_60.00 --pos 1920x620
--rotate normal\
       --output DVI-D-1 --mode 1920x1200 --pos 0x620 --rotate normal)

${XRANDR[@]}
```
