Default Twinview widscreen problem

Hey everyone,

I have just got my self a new 22" acer widscreen monitor.
I have it setup in twinview with a 17" LCD.
I am trying to get th 22" to work at its natural 1680x1050 res with my 17" running at 1280x1024.
For some reason the monitor turns off when i try this combo of res. I can get each monitor to work individually at these res.

Here is some of the xorg.conf
Option "TwinView"
Option "SecondMonitorHorizSync" "31.5 - 60.7"
Option "SecondMonitorVertRefresh" "60 - 75"
Option "TwinViewOrientation" "RightOf"
Option "MetaModes" "1280x1024, 1680x1050"

I have had twinview with 2 17" LCD working fine in the past.
At he moment I have it running at "1280x1024,1024x768", it will let me do that.
PS(i have got it to work in windows)
thanks

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

and then generate and attach an nvidia-bug-report.log.

Thanks,
Lonni

ok I have done the log but it was to big to attach

I think i found the problem in the log though

THis is not right. The monitor can go to ~160 Mz

Ok I tried adding in
Option "ModeValidation" "NoMaxPClkCheck"
to xorg.conf
and I tried manually setting the virtual screen size with no luck for either

Ah, yet another EDID bug that nVidia claims doesn't exist.

Maybe if they fix this then HDTV sets will work without custom modelines. Good luck though.

P.S. Load up Windows and watch it magically work. netllama, please stress EDID still has issues.

mooninite,
I'm not really clear on what you're referring to here as no one from NVIDIA has commented at all on the content of this thread.

Thanks,
Lonni

krisnilsen,

It sounds like the GPU is reporting a hardware pclk limit of 165 MHz, but the flat panel is reporting its own (incorrect) limit of 135 MHz. Accordingly, you'll need the NoEdidMaxPClkCheck override, rather than the NoMaxPClkCheck one, which overrides the GPU limit.

Hey everyone I have fixed it.

I found this in the log

(II) NVIDIA(0): Validating Mode "1680x1050":
(II) NVIDIA(0): 1680 x 1050 @ 60 Hz
(II) NVIDIA(0): Mode Source: X Server
(II) NVIDIA(0): Pixel Clock : 147.14 MHz
(II) NVIDIA(0): HRes, HSyncStart : 1680, 1784
(II) NVIDIA(0): HSyncEnd, HTotal : 1968, 2256
(II) NVIDIA(0): VRes, VSyncStart : 1050, 1051
(II) NVIDIA(0): VSyncEnd, VTotal : 1054, 1087
(II) NVIDIA(0): H/V Polarity : +/+
(WW) NVIDIA(0): Mode is rejected: HorizSync (65.2 kHz) out of range
(WW) NVIDIA(0): (31.500-60.700 kHz).

Then noticed that i had manually set the second monitor HSync and VSync
Commented them out and hay presto worked
Thanks for your help everyone (stupid me)
