    Default HDMI output not working with a 5770

    Hey all!

    I'm trying to use my TV with the HDMI output of a 5770. It just doesn't seem to work. xrandr sees nothing:

    Code:
    rune@runescomp:~$ xrandr --verbose

    Do I have to edit my xorg.conf to make it work? Currently I have no xorg.conf.

    Running Ubuntu Natty (kernel 2.6.38-15-generic) with the following radeon driver:
    Code:
    une@runescomp:~$ apt-cache policy xserver-xorg-video-radeon
    xserver-xorg-video-radeon:

    It would appear that the results are exactly the same when using Precise:

    I don't think it's a software problem. Are you sure the cable is ok and is fully plugged in (the HDMI plug is really bad designed...)? Do you see output on the TV when the computer is booting?

    I just found these messages in dmesg:
    Code:

    This message repeats multiple times.
    Ever since I plugged in my TV into the HDMI port of my video card, I would get occasional hanging in the boot-up process. Sometimes the Ubuntu loading screen would just hang, other times my monitor (which is connected to the DVI-0 port) would turn off, saying "No signal". When this happens, and it all seems completely frozen, if I pull out the HDMI plug, *bang* monitor turns back on and I get to a login prompt and everything works fine.

    Here's the full dmesg: http://pastebin.com/uqyiWrpS
    and dmesg.0: http://pastebin.com/6CFTC5AJ

    I've used this same TV, albeit with another video card, so I know that the TV at least *can* work. With that video card the EDID block was able to be parsed.

    I'm using a 7.5 meter HDMI cable. Maybe it's too long?

    Actually, I'm not sure no. The PCI bracket of the card is somewhat covered up by the metal from the case that separates the PCI slots the video is in from the other slots. So the HDMI plug hits this piece of metal from the case when going in to the socket. I'm not sure it's getting all the way in.
    Also, the cable is 7.5 meters in length. Could this also be a problem?

    I see no output on the TV at all.

    If you don't see an output before linux starts, it's not a software problem.

    The cable length should not be a problem. I have a radeon 5770 + 1 monitor connected via DVI + 1 TV connected via HDMI (10m cable) and this works without problems. Well mostly, sometimes the HDMI unplugs itself if I move the computer (really bad design choice to have the plug without any screws, clips or anything else that stops it from unplugging itself...). But other than that, it works.

    If I read that right, your HDMI plug is grounded via the computer case?

    I see, droste, good to know. I'll test with the DVI port using a DVI-to-HDMI adapter as soon as I get my hands on one. Maybe I'll have to remove some of that metal from my computer case so the HDMI connector can get in all the way. I mean, it seems it's already plugging in fully, but I can't really see if it could go in further.

    I don't know. It's just that the plastic part of the HDMI connector (not the metal part as far as I can see) hits the computer case when I plug it in. So it might be able to go in further, but I won't know without either removing the video card from the case (and possibly using it with a PCI extender to test it) or by removing some of the metal from the case.

    EDIT: As you can see in the following picture, the HDMI connector is pretty close to the edge of the PCI bracket. They should have placed it further in towards the middle of the bracket, since the edge of the bracket is covered by the metal piece on the computer case that separates the various PCI slots from each other. So the actual hole isn't covered, but a HDMI connector is wider than only the male connector itself that goes into the hole.

    Ok, this is strange: now it works perfectly. I got my hands on a DVI-to-HDMI adapter, booted up the computer with the TV plugged into this, and it worked. Then I put the HDMI connector back into the HDMI port on the card and now this also works. No messages in dmesg or anything. Strange. But good!

    Now I'm only having some problems with Ubuntu placing the GNOME panel on my TV. And the fact that there's a lot of overscan on the TV just adds to this annoyance since I can't see the panel because of this.

    EDIT: Yay! I got the overscan issue removed by telling my TV that it is my PC that's connected to it via the HDMI1 input. Now if only Ubuntu would place the top panel on my monitor...

    try xrandr --output DVI-0 --primary

    (I don't know if it really works, I'm using KDE)
