Public bug reported:
Braswell + UBUNTU 15.10
when LVDS is enable in Bios,, a Device called "eDP1" appears connected
and this is the internal LVDS device with the right settings for the
1366x768 display that was set in the Bios and a "DP2" device is
connected also (this is the SVGA Monitor and shows all modes supported
by the SVGA monitor that I have plugged in the VGA port as well its EDID
information. All others devices (DP1, HDMI1, HDMI2 have their status as
"disconnected".See below this information that is in the
"xrandr_q_verbose_LVDS_Enable.txt file
When the LVDS is disable in Bios, I didn't see the eDP1 device, but the device
"DP2" that was the VGA monitor when the LVDS was enable in BIOS, now appears as
"DP3" and the "DP2" device appears as connected (this is the device that
appears in the graphical monitor settings (1024x768 with no EDID information.
All other devices appear as disconnected (DP1, HDMI1, HDMI2 and another HDMI3
that was not in the system when LVDS was enable in Bios).
