Previous 7676 dualscreen configuration not working under 8174

ateam · 12-07-05, 05:53 PM

I've been using dualscreens with my GeForce FX5600 XT for a year now, and have never had a problem. Upon upgrading to the 8174 drivers, I get an error about resolution and frequencies, etc.

I've attached my nvidia-bug-report.log and Xorg.0.log files. Below is the contents of my xorg.conf file...

Code:

Thanks everyone in advance :-)

This looks to be a problem:
(II) NVIDIA(0): Using ConnectedMonitor string "DFP-0, DFP-1"
(WW) NVIDIA(0): Inappropriate ConnectedMonitor string.
(II) NVIDIA(0): Connected display device(s): CRT-0, CRT-1

Why are you using the ConnectedMonitor option?

Can you generate a bug report from 1.0-7676 where this is working?

Thanks,
Lonni

I tried commenting out the ConnectedMonitor line and was still given the same error.

Here is my nvidia-bug-report.log file from my current, working 7676 system.

netllama · 12-08-05, 12:08 PM

Can you please post a bug report against 1.0-8174 when ConnectedMonitor is not in use?

And again, I'm asking, why are you using that option at all?

Thanks,
Lonni

ateam · 12-08-05, 04:17 PM

Like I said, I commented out the ConnctedMonitor line and got the same error.

Either way, here is another bug report with the 8174 drivers, this time with the line commcted out.

netllama · 12-08-05, 04:39 PM

Thanks. Please start X with the following command:
startx -- -logverbose 6

and post one more bug report. I suspect I know what might be going wrong, but need to see the EDID to verify.

Thanks,
Lonni

I'm glad you're making headway!

I REALLY appreciate all of the help you've given and time you've taken up to this point. Hopefully we'll get this issue resolved.

Here's the new report with increased log verbosity.

ateam · 12-08-05, 06:05 PM

I figured it out!

After thinking about your mentioning of the EDID, I decided to take a look in the bug report myself. It seems that the monitor sync and refresh rates I was using weren't exactly accurate. So... after some reading on the X.Org site, I changed my config file to the following:

Code:

HorizSync       30-80
VertRefresh     60-75
DisplaySize     677 271

Instead of...

Code:

HorizSync       31.5-64.3
VertRefresh     50-70

And...

Code:

Option          "SecondMonitorHorizSync"        "30-80"
Option          "SecondMonitorVertRefresh"      "60-75"

Instead of...

Code:

Option         "SecondMonitorHorizSync"        "31.5-64.3"
Option         "SecondMonitorVertRefresh"      "50.70"

Now that my display size and EXACT rates are specified, all is working well with the new drivers. It's actually a good thing that this little bump in the road happened, because now I have a more accurate X setup.

Thanks nVIDIA team, and thanks netllama for all of your help! I assumed the problem resided in my sync and refresh rates, and now everything is working smoothly.
