Re: hdmi out
OK, with tail -f ... messages, I do see a burst of messages and the projector shows the exact screen. But only for 15 seconds, when the projector then goes blank and reverts to _No Signal_ until I touch something on the XO like the screen, track pad or some key. Apparently the XO has stopped sending hdmi signals, so the projector is reporting exactly that. Is this the XO hdmi port going to sleep? And do I have control over some time constant? Or perhaps my projector is going blank when it sees no recent activity on the port. Might it be expecting at least a screen refresh over the hdmi channel? I don't have a projector manual that would describe that ... It seems I can jiggle the HDMI cable a fair bit without issue, so I think the physical connection is sound. Just not clear on who is exercising the time constant in between gestures to the XO. -- b On 18/08/2013 4:00 p.m., Tom Parker wrote: On 18/08/13 15:01, Barry Vercoe wrote: Tom, attached is a file dmesg.output.

Is this a 13.2.0 build or something older? I can't remember at what point we added the hooks to let powerd check for the hdmi connection status and act accordingly. -Jon ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: hdmi out
Of Course!! I used to have that problem when I played long Csound demos -- overworking the Flt Pt processor yet untouched by human hands ... I don't know why I didn't relate the two situations. Turned off power saving, and the problem immediately went away. No, power saving doesn't turn off automatically when hdmi is plugged in. Perhaps it should ... Or at least we should have a warning distributed with the hdmi cable that the port will turn off after 15 seconds with power saving on. Thanks all. -- b On 18/08/2013 5:26 p.m., Tom Parker wrote: On 18/08/13 17:05, Barry Vercoe wrote: OK, with tail -f ... messages, I do see a burst of messages and the projector shows the exact screen.
