Hi,
I’ve got a BBB running Ubuntu 13.04 on the eMMC connected to an HDMI monitor where I want to display a webpage hosted on the BBB. I’m do this by starting an X Server and then launching a broswer:
xinit &
DISPLAY=:0 chromium-browser
The page is displayed, but anything that should be blue is red, and everything red is blue. Green stays the same. If I use a terminal on the HDMI display by plugging a keyboard into the BBB the colours appear as they should, but I can’t get anything in X to look right.
I’ve tried Ubuntu 13.10 on another BBB and it had the same problem. I also tried the default Angstrom image and the desktop looked normal on that. I’ve tried all the supported resolutions for this monitor that I got from “xrandr -q” and they all had the same issues. I also tried another model monitor with the same issue. I tried Firefox as well and had the same issue.

Seems this has happened to others: https://groups.google.com/forum/?fromgroups=#!searchin/beagleboard/bbb$20colors/beagleboard/l3VogAknB5Q/PBCHhZHzLeoJ
Any ideas on how to fix this, or suggestions on how to display a webpage on the HDMI without using X Windows?
Thanks,
