Hi!
I'm currently trying to enable the 2nd display on our Bay Trail
Atom E3845 SoC. This is on the Congatec SoM "conga-QA3":
http://www.congatec.com/en/products/qseven/conga-qa3.html
On this SoM, the eDP is converted to LVDS via an NXP PTN3460
and available as LVDS on the baseboard. My current setup is that
the 1st display is connected to HDMI1. This works just fine.
In the production version I would like to use a LVDS display
connected via eDP from the Bay Trail Atom. Since we don't have
this LVDS display yet, I'm currently testing with this
LVDS -> DVI adapter board:
http://www.congatec.com/de/produkte/zubehoer/conga-ldvi.html
So my current setup for this 2nd display is:
eDP -> LVDS -> DVI
which does not work.
Here my xrandr output:
Screen 0: minimum 8 x 8, current 1920 x 1200, maximum 32767 x 32767
DP1 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
HDMI1 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 597mm x 336mm
1920x1200 59.95*
1920x1080 60.00
1600x1200 60.00
1680x1050 59.88
1280x1024 75.02 60.02
1280x800 59.91
1152x864 75.00
1024x768 75.03 60.00
800x600 75.00 60.32
640x480 75.00 59.94
720x400 70.08
HDMI2 disconnected (normal left inverted right x axis y axis)
VGA1 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)
When I now try to add and enable DP1 (this is the correct port for
the eDP, right?), then I get these errors / warnings:
sudo xrandr -d :0 --output DP1 --addmode DP1 640x480
