There are supposedly 2 gpu's in this chipset. Mali 400's ack the log.

In /etc/X11/xorg.conf.d/ there are 3 files
20-armsoc.conf:
Section "Device"
        Identifier      "Mali FBDEV"
        Driver          "armsoc"
        Option          "fbdev"                 "/dev/fb0"
        Option          "Fimg2DExa"             "false"
        Option          "DRI2"                  "true"
        Option          "DRI2_PAGE_FLIP"        "false"
        Option          "DRI2_WAIT_VSYNC"       "true"
        Option          "CursorPlaneType"       "2"
EndSection

Section "Screen"
        Identifier      "DefaultScreen"
        Device          "Mali FBDEV"
        DefaultDepth    24
EndSection

And
20-modesetting.conf:
Section "Device"
    Identifier  "Rockchip Graphics"
    Driver      "modesetting"
    Option      "AccelMethod"    "glamor"
    Option      "Dri2Vsync"      "false"
EndSection
And a .bak copy of the above.

I'm doing all this from an ssh login, and for some (security I assume) 
reason there are pauses in the boot that need the return key pressed.
And until it has tried to start x, there is no network. Security concerns
are starting to be a PITA. Thus is a well isolated home network, dd-wrt
in the router is my guard dog and has very sharp teeth.

Its in the garage (my 2nd mancave) and I'll have to dress and go out
to reboot it. Early, and I need to feed the missus first, she's stuck
in a recliner with a broken leg. Paper mache for bones at 78, and I'm 83.

Mali is mentioned in the kern.log. let me see if I can find that and paste it:

Thank you Michal, results in a later post after its been rebooted. I
should have included this stuff in the first post.
