Title: Teres HDMI out to monitor not operational
Post by: starkwether on February 15, 2018, 11:29:59 pm
Hello-

I built a Teres the other day and I really enjoy it. Everything has been pretty painless except that I cannot get HDMI out to a monitor. Rather, I get 'no signal'.

My cable is ok and I've tested multiple HDMI displays. No luck. Is Fn + F9 supposed to do something display related?

I am looking into x config stuff now but thought I'd see if anyonen had similar issues.

Output of xrandr --verbose is:


xrandr: Failed to get size of gamma for output default

Thanks for the notice, HDMI out is not working currently. We are working on it.

Thank You LubOlimex. I don't suppose a HDMI to DVI or VGA would make a difference? I'm no expert but is there anything I can do to help out?

Adapter will not make a difference, it is not enabled in the software. We are working on it.

I guess the HDMI output is still not working. Just installed the newest updates, but nothing on my external monitor. I would like to use the Teres to present on a beamer so I need the HDMI output. On Github I saw that someone is working on it, however did not see the real progress.

Which image version do you mean? The latest one from Software section of the product page (ubuntu mate) from Dec 2017 does not seem to support it.
