right now i'm using ubuntu 16.04 with an additional KDE plasma5 dektop
on a Pansonic FZ-g1 toughpad with an external gechic hdmi touchscreen
> 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 > Kernel driver in use: i915 > Kernel modules: i915
xrandr or sure also arandr does not show my hdmi port as connected
> xrandr > Screen 0: minimum 8 x 8, current 3840 x 1200, maximum 32767 x 32767 > eDP1 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 0mm x 0mm > 1920x1200 60.00*+ 59.95 > ....... > DP1 disconnected (normal left inverted right x axis y axis) > HDMI1 disconnected 1920x1200+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm > 1920x1200 60.00* > VGA1 disconnected (normal left inverted right x axis y axis) > VIRTUAL1 disconnected (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
> 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 connected ?
so i do the following to map the internal display to the internal touch
[CODE]xinput map-to-output 15 eDP1[/CODE]
Ok, that works and the internal touchscreen is quite precise now.
But doing this with the not connected hdmi touchscreen gives following error
> xinput map-to-output 20 HDMI1 Unable to find output 'HDMI1'. Output > may not be connected.
that makes the external touchscreen unusable cause it makes the curser jump to the internal 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
added following grub bootoption
installed intel driver with a tricking ubuntu 16.04 to be 15.10
added following xorg.conf (not knowing if xorg.conf is even used anymore)
> 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 connect 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
