Default HDMI EDID regression?

Hello

I just upgraded to Ubuntu 10.10. and the 260.x version of the driver. The driver itself works fine with my card but I have a monitor connected through HDMI that doesn't want to play nice.

I had that issue before as well - with ubuntu 10.04 and an older version of the driver - can't really remember which version it was. Then Nvidia released a new version and I remember reading in the change log that the handeling of EDID frequences had been updated... After that everything worked great. There was no problem switching between display settings and enabling HDMI.

Now I have the same problem with the screen not waking up from sleep mode when enabling it in nvidia-settings. It works without problems with the nouveau driver and in windows.

Is this a know problem? I have spent 2 hours searching the these forums, the ubuntu forums and googling but I can't find anything.

I'm attaching the nvidia-bug-report and the edid.bin that I downloaded through nvidia-settings.

I have also noted that most of the time nvidia-settings shows the DFP-1 information as unknown. There have been times were the resolutions have shown up but I haven't been able to make out a pattern. See attached screenshots.

The monitors are all Dell Full HD 24" monitors.

I also just tried with the latest drivers, 260.19.12, that were released today.

No luck. =(

Is there anything I can try?

E.g. setting refresh rates in xorg.conf or using the CustomEDID parameter.

I found the following in the change log for driver 190.42.
Quote:
Updated the NVIDIA X driver to allow, on GeForce 8 or greater GPUs, more modes to validate on digital display devices whose EDIDs report very constrained HorizSync or VertRefresh ranges.
I think it was that that fixed it last time. Hence the question about the regression.

I don't really have a clue where to start looking...

I have a similar issue. Seems to be a regression.

My ION box works perfect with Ubuntu 10.04.1 (with older drivers) but not with Fedora 14 (with newer drivers).

I just tried the latest 260.19.29 update and the problem remains.

Is there ANYTHING I could try to make it work?
Should I try to update my EDID? Are there any settings that I can put in my xorg.conf file that might help?

Thanks

Try making custom modelines, seemed to work for me:

One can also get the Modelines from the Xorg.0.log when using nouveau.

I have finally managed to create a bug report.

There seems to be something fishy with the EDIDs.

I have tried every version of the 260 series of the driver as well as the new 270 beta and none of them were able to wake the screen up from standby mode.

I tried the 173 driver bundled with ubuntu and it works! (At least the screen shows an image but there seem to be servere performance issues with twinview)
