[LIVE] Hdmi handshake issues (ION)

I reset my x.org and tried to simulate your problem. The edid lines are not needed. Only the ConnectedMonitor and Modelines are needed for this. This is my xorg.config:

Make sure your resolution in XBMC is also set and matches the one in your Xorg config!

i must say THANK YOU, so mutch for this xorg.conf file it works perfect with my Onkyo-875 i was never able to get one to work.

erhnam,

I am curious; most ION motherboards have at least a vga- and an hdmi-output. Would it be possible to output the same signal ('clone mode') to both outputs? If yes, how would you manage this?

I have a projector that I want to keep attached to my XBMC box, but even if the projector is turned off, XBMC thinks there is something attached to the VGA port. The result: a blank hdmi screen. If I force hdmi output (through "ConnectedMonitor") I get an image on my hdmi tv, but nothing on the projector. I would have to switch config-files and restart X11 to get the projector working, which sounds quite bothersome to me.
Kodi v17 "Krypton" Beta 6 running on Amazon Fire TV (2014) with FLIRC receiver.

I know it can be done in windows because I had my LCD TV on at the same via HDMI that my VGA was on.

I've been working at this for the last couple of hours with no success. I think that the problem might lie with my tv. I get the following lines in my Xorg.log:

I've tried setting - Option "ConnectedMonitor" "DFP-0" - but that didn't seem to fix my handshake problem. And I'm not sure what to set my ModeLine properties to since Xorg.log seems to land on "nvidia-auto-select."

Any ideas?

clear up your xorg.conf. Generate a new one and try again.

Thanks man. I gave that a try but it didn't seem to make a difference.

Hm. It appears that I have the same problem even if I directly boot into the BIOS. So I'll start up the computer, hit F2 a bunch, and load up the BIOS. Then, when I change inputs and come back, I no longer get the HDMI signal anymore.

I'm guessing that doesn't have anything to do with xorg?

OK, I know NOTHING about TV, but looking at the specs of your TV it says its screen resolution 720p, but its accepts up to 1080i via HDMI. Is it possible that this contradiction is causing Xorg to be too clever and it gets confused, since the input says it can handle 1080i, but the screen says it can handle 720p.

If you can find a way to force Xorg to stick to 720p it might fix it. Though how to do it, who knows....

Here is someone with your TV with a working xorg.conf, but not sure what connection:

Interesting.

I tried changing my xorg.conf file to match the guy's in the link that you provided, prupert, but was still experiencing my problem. Then I tried updating xbmc to the new release candidate, and still had the same problem.

Then I went to bed, and left my ASRock *on* for the night as punishment for not doing what I wanted it to.

When I woke up in the morning, I turned my TV on, and switched over to my HTPC input (HDMI1) and lo and behold, the signal was no longer lost. I was looking at XBMC instead of that stupid "No Signal" text. I tried again, switching my input to Component 1, and then back to HDMI 1 and (huzzah!) once again it worked!

I was so excited that I called my wife into the room to show her. "Watch this," I said, switching the inputs to Component 1 and back to HDMI1. I couldn't believe it when the TV was telling us both, once again, that it had "No Signal."

"Impressive." She said sarcastically.

"Fuck." Was my only response.

Trying again, over and over this morning, I was not able to get the HDMI signal to be regained. When I get home again today, I'm going to try switching out the HDMI cable, but I'm starting to think that it's a hardware problem and I might need to send my ASRock back. Sad

LMAO,

on a side note, I am having the same problem. Using RC1 but for some reason I don't have an xorg.conf, I have a XF86Config that will not retain any changes it to it and if I try to rename/delete it and use an xorg.conf instead, my asrock boots to the login screen.

My inputs change over fine but my signal is intermittent when connected, it will just drop out all the time, sometimes every once in a while and other times it is constant. Maybe I should check my cable?

Gr8 story spoenrope, it made me smile, but I guess you weren't.

It does sound like a hardware problem, most likely a cable issue, that's what I would check.

Have you tried searching the ubuntu forums for similar problems? Since if it isn't a hardware problem, it is likely an xorg problem. Or go to x.org and try their IRC, I have got good help from IRC channels in the past:

Thumbs Down 
Spokenrope, great story.

I've spent so much time fighting this problem, I'd probably sooner figure out how to turn potatoes into gold. Funny thing is, at one point, I got it working! I was so happy, put up my keyboard, used my HTPC for an afternoon. Flicking to a random tv input and back again. Turning the tv on and off just for kicks. Then I leave for a few hours to visit family.

When I get home, it's nothing but "No Signal" again. Best I can tell, HDMI stands for High Def Made Impossible. Sad

I hate that my first day in 2010 was spent fighting crap technology. The future, you embarrass us all.

hey soaponarope
I had a similar problem to you. My ION wasn't handshaking with my TV (either via the receiver or direct). Finally fixed it.
I looked through /var/log/Xorg.0.log to determine if I should use DFP-0 or DFP-1 in my xorg.conf (for me it was DFP-1).
Then I used erhnam's conf from earlier in this thread ->
Reboot and all works fine.
My TV is full HD and can play 24p so no worries there.
Also, be sure that your TV is on before you power up.
Cheers.
