            Bug ID: 105406
           Summary: No internal display on kernels > 4.4.x
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: david at majinbuu.com

I have a J2-680L POS (Point Of Sale) that runs Manjaro Linux. The problem is
that ANY kernel newer than 4.4.x will not enable the internal display and I am
forced to use an external display.

This has been duplicated by testing with the latest releases of Fedora, CentOS,
Debian and Ubuntu.

The internal display will work up untill GRUB, after GRUB the display will go
blank and is not detected by the system. This happens whether I am using
modesetting or xf86-video-intel.

Here are a few bits of information relating to the system. If anything else is
needed please let me know...

xrandr - NOTE: the internal screen is detected as connected on DP-2

hwinfo --monitor

hwinfo --gfxcard

As a side note i also tried creating a x11 intel.conf containing:

Section "Device"
        Identifier  "Intel Graphics"
        Driver      "modesetting"
        BusID       "PCI:0:2:0"
EndSection

To no avail which has now lead me to believe this is an regression.

Thanks.
