xrandr does not "coect" to intel i915 HDMI output

Hi there,
right now i'm using ubuntu 16.04 with an additional KDE plasma5 dektop
on a Pansonic FZ-g1 toughpad with an exteal gechic hdmi touchscreen

Code:

lspci -ks 0:02 
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
    Subsystem: Matsushita Electric Industrial Co., Ltd. 3rd Gen Core processor Graphics Controller
    Keel driver in use: i915
    Keel modules: i915

xrandr or sure also arandr does not show my hdmi port as coected

Code:

xrandr
Screen 0: minimum 8 x 8, current 3840 x 1200, maximum 32767 x 32767
eDP1 coected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1920x1200     60.00*+  59.95  
.......
DP1 discoected (normal left inverted right x axis y axis)
HDMI1 discoected 1920x1200+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1920x1200     60.00* 
VGA1 discoected (normal left inverted right x axis y axis)
VIRTUAL1 discoected (normal left inverted right x axis y axis)

but i managed to trick x with following lines and the touchscreen shows with black background, but works pretty well as dual monitor now

Code:

xrandr --addmode HDMI1 "1920x1200"
xrandr --output HDMI1 --mode "1920x1200" --right-of eDP1

my problem is that the touch calibration does not seem to work for two displays if x just knows one as coected ?
so i do the following to map the inteal display to the inteal touch

Code:

xinput map-to-output 15 eDP1

Ok, that works and the inteal touchscreen is quite precise now.
But doing this with the not coected hdmi touchscreen gives following error

Code:

xinput map-to-output 20 HDMI1
Unable to find output 'HDMI1'. Output may not be coected.

that makes the exteal touchscreen unusable cause it makes the curser jump to the inteal display, or anyway in some random way, but not where i actually touch

so i think the solution with forcing x to display the second monitor to show is not the solution, cause it's neither "design integrated" in unity or plasma nor arandr and other graphical convenient tool recognize the second display.

i tried the following unit not
FIRST:
added following grub bootoption

Code:

i915.modeset=1

SECOND:
installed intel driver with a tricking ubuntu 16.04 to be 15.10
https://01.org/linuxgraphics/downloa...er-linux-1.4.0
THIRD:
added following xorg.conf (not knowing if xorg.conf is even used anymore)

Code:

Section "Device"
    Identifier "card0"
    Driver "intel"
    VendorName  "Intel Corporation"
    BoardName   "Intel Corporation N10 Family Integrated Graphics Controller"
    BusID       "PCI:0:2:0"
    Option      "SwapbuffersWait"    "false"
EndSection

any ideas either getting x to coect to the hdmi port or to "force" mapping the touchscreen to the hdmi output by something like "xinput map-to-output 20 HDMI1" ?

thanks in advance
