Cool. I'll re-test based on that.

I don't see anything different with respect to displays, and
my "modes" entry is coming up the same as yours:

	root at trusty-dev:~# cat /sys/class/graphics/fb0/modes
	U:1920x1080p-0

My command-line also matches yours with respect to video:
	root at trusty-dev:~# cat /proc/cmdline
enable_wait_mode=off video=mxcfb0:dev=hdmi,1280x720M at 60,if=RGB24,bpp=32
video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off fbmem=28M
console=ttymxc1,115200 vmalloc=400M consoleblank=0 rootwait fixrtc
root=/dev/mmcblk0p1 mxc_hdmi.only_cea=1 splash quiet
plymouth.ignore-serial-consoles

Note that the mode request (720P) isn't supported by the
kernel, and I'm getting 1080P resolution.

I'm currently booting an image that contains X acceleration, and
the Vivante drivers aren't coming up, so I'm getting a login
prompt on /dev/tty0.

What userspace are you running?

Is it possible that you're up and running, but nothing is
starting because of an X configuration problem?

Sure. I'd be happy to.
