hey Cecil,

I have a freshly burned CD of 7.3 I'm trying to install on an AMD based motherboard with an nVidia GT220 (or near) video card.

It's hooked to a 42" Toshiba Regza TV via HDMI (on the TV) plugged into the DVI port of the video card.

When the system boots, video properly shows up on the screen, but as the install boots, eventually the video just hangs. I think the VGA port of the card is being used at that point (I need to drag a VGA monitor into the same room as the TV to verify).

BUT, I installed LinHES in the room WITH a VGA LCD... and it works. All the way through. Then, when I go back and plug in the now working system to the DVI/HDMI based LCD TV, the system just seems to loop at the yellow/blue LinHES screen starting it's starting up.

I imagine this is a simple fix of sorts in the Xorg.conf (isn't it always?) -- but thought I would let you know since it doesn't "install out of the box" without needed some additional tweaking.

Cheers,

-Ben

Additional info: the Video Card is only seeing the VGA monitor anyway and not the LCD via HDMI->DVI (derp)

[root@myth-fe1 X11]# nvidia-xconfig --query-gpu-info

  Number of Display Devices: 1

  Display Device 0 (CRT-1):
     EDID Name             : Samsung S/M 150MP
     Minimum HorizSync     : 30.000 kHz
     Maximum HorizSync     : 70.000 kHz
     Minimum VertRefresh   : 56 Hz
     Maximum VertRefresh   : 85 Hz
     Maximum PixelClock    : 100.000 MHz
     Maximum Width         : 1024 pixels

     Preferred Height      : 768 pixels
     Preferred VertRefresh : 60 Hz
     Physical Width        : 300 mm
     Physical Height       : 230 mm


More info: If I switch the VGA monitor to the DVI port with an adapter and reboot the system, it can be detected as shown below. (note the CRT-# has changed)

Code:
[root@myth-fe1 ~]# nvidia-xconfig --use-edid --probe-all-gpus --query-gpu-info

     Minimum VertRefresh   : 56 Hz
     Maximum VertRefresh   : 85 Hz

     Maximum Width         : 1024 pixels
     Maximum Height        : 768 pixels
     Preferred Width       : 1024 pixels
     Preferred Height      : 768 pixels
     Preferred VertRefresh : 60 Hz
     Physical Width        : 300 mm
     Physical Height       : 230 mm


So, I guess the question is: the DVI->HDMI cable is like 10ft.. are there EDID detection problems common to these kinds of adapter cables?

Well then... JUST for fun, I plugged the computer into HDMI-3 instead of HDMI-1 (TV has 3 ports) and look what nVidia reports NOW!

I have a Samsung LCD TV that does something similar, refuses to display anything but 60Hz on all it's HDMI ports except for HDMI 2, which has an edid with every mode you could ever want....

So it works on port2 as you'd expect?

I'm curious to just configure Xorg.conf to what I want -- as the TV's speakers don't work with HDMI-2/3 -- only PC/HDMI-1

(shaking head)

We've been inundated with (no so cheap) non-standards complaint gear. It's just shocking some days.

My Samsung works on HDMI 2 like a champ!

Has any mode I could ever want on there....all I ever needed to add in my Xorg.conf is: "1920x1080_50" and maybe set scaling to:

Code:
Option         "FlatPanelProperties" "Scaling = Native"


I guess you could try grabbing an edid.bin from the friendly port and try loading that in your Xorg.conf while running on a recalcitrant port??
The edid.bin from my TV's HDMI 2 http://members.wideband.net.au/htd/Hostedphotos/edid.bin

Actually my brother has an awful,awful older LCD TV that has no info whatsoever on the only HDMI, I think I just forced that the old fashioned way with a PAL modeline.
