6600 with Sampo PME-42S6 Plasma

[timtt]

Hi everyone,

I searched the forums and could not find an answer to my problem. I am connecting my Linux Box (FC4 with 7676 nVidia driver) to this plasma via VGA, since DVI does not support the 720p and 1080i resolutions. Attached at the bottom of this post is my xorg.conf file to show some of the Modelines I'm working with. The problem I have is that the picture is always off the left side of the screen with the HDTV resolutions by about 50-100 pixels even when I move the picture with the TV settings as much as I can. With the 852x480 resolution (panel native), portions are off the right side. So here are my questions:

1) What's the best resolution to drive this panel with? It's for a MythTV setup.
2) I tried a number of HSkew and other parameters, but couldn't get any of them to work. Is there a way (and what is it) to align the picture on the TV without touching the TV controls?
3) Is VGA the way to go? DVI won't work. Should I return the 6600 (256MB RAM) and get a different one? Is component the way to go?

The TV does accept the 1080i and 720p connections via VGA when I set them up, so that's ok. Anyhow, any pointers, info, etc would be extremely helpful!

Thanks,

Tim

P.S.: The Viewport line under "Screen" made no difference.

Please start X with the following command:
startx -- -logverbose 5

and then post a bug report for review.

Thanks,

Ok, at home now. Here is the file. The only way I was able to generate the file was to login remotely into the server, delete the /tmp/.X0-lock file and then startx. I didn't want to intentionally break the xorg.conf file to prevent gdm from starting in order to get the text-based login. I didn't know how to disable gdm, so I hope this works.

Thanks,

Tim

What you attached is not a bug report. Please start X with the following command:
startx -- -logverbose 5

and then post an nvidia-bug-report.log for review.

Thanks,
Lonni

Hi Lonni,

Sorry about that. I had two points of confusion. First, I didn't read the sticky post about the nvidia-bug-report.log script and then the script wasn't part of my install. I had gotten rpms via yum from somewhere (lvn?). I removed the rpms and reinstalled via the nVidia install scripts and now I ran the bug report. Just to note, it was run with the 720p resolution from the above xorg.conf file that's commented out. I can't see about 80 or so pixels on the left side of my monitor (16:9 aspect ratio FYI.

I had to split the file in two because it was 107 kb (above the 100k upload limit).

Thanks,

Tim

This bug report indicates that you're using the 'nv' X driver, not the 'nvidia' driver.

Lonny,

Wow, I spaced on that one. I forgot that the rpm erase would change the xorg.conf file. Hence the misconfiguration. My apologies. I've now included both files. Let me know if you can make anything of it.

Thanks so much for looking into this even at this late hour!

Best,

Tim

[timtt]

DP - sorry

[netllama]

You need to remove IgnoreEDID from your X configuration in order to capture the EDID with the command I provided. Please do so, and generate a new bug report.

Thanks,
Lonni

[timtt]

Here it is - two parts due to file size of 100.3 kB.

Thanks,

Tim

Thanks, now I see what I need. Unfortunately, the EDID in your display isn't the least bit useful.

I do see this in your X log, which may or may not be relevant to the problem you're having:
(WW) NVIDIA(0): Probed monitor is 920x520 mm, using Displaysize 848x480 mm

What you can try at this point is using xvidtune to tweak a modeline to correct for the drift.

Thanks,
Lonni
