Description
Hi Eric,
Amazed at the progress you're making.
I have an issue that the screen is black at the default 1920x1080 resolution. infrequently i get a picture for about a second and then it disappears again, setting the raspberry pi to output a resolution of 1280x720 does work.
by the way, probably a separate bug (and can file separately if you like) changing the screen resolution via /opt/vc/bin/tvservice causes a purple line(s) to appear at the screen edge(s).
I would like to post any relevant info you need to catch what's going on but I don't know what it is you need.
I'm running on a raspberry pi 3 with arch:
Linux alarmpi 4.4.8-1-ARCH #1 SMP Fri Apr 22 18:47:51 MDT 2016 armv7l GNU/Linux
config.txt:
hdmi_group=1
hdmi_mode=4
disable_overscan=1
framebuffer_depth=32
gpu_mem=256
dtoverlay=hifiberry-dacplus
dtoverlay=vc4-kms-v3d
avoid_warnings=2
The monitor i'm using works fine with other devices at 1920x1080 60/59mhz.
So grateful for your work, pretty soon I'll enjoy my raspberry pi almost as much as I do cookies.
