Mode is rejected: Mode (2560 x 1600) is too large for DFP

Grrrrr.

Option "ModeValidation" "NoMaxPClkCheck,NoEdidMaxPClkCheck" in the Monitor section, but on the other forum, he had put it in the Screen section, so I tried both.

Well noticed, well done, but still no better.
Maybe try your idea of Option "NoBandWidthTest" "1" with my xorg.conf, not the one you tried that had a bad dotclock rate, or have you already retested that?
I am going back to the nvidia driver docs to have another read of them.

=> Another thought.... You remember near the beginning of this thread, when we tried the Option "UseEDID" "FALSE" line in the Device section? It didn't work because we hadn't (then) realised that we need to specify a modeline for 2560x1600 and interlace it.

It is worth another try: Start afresh with "my" xorg.conf as posted, add only the Option "UseEDID" "FALSE", do not add any other options, check the logs, round we go again.

I think that was actually a fix for a problem that existed with an Integrated Graphics Chipset that was on one of the nForce boards. I read through it too quickly to realize it the first time.

Regardless, I tried it again and got nothing.

Without starting fresh, but only adding Option "UseEDID" "False", here's my Xorg.0.log:

As you might suspect, both times I had a black screen...

I find this interesting:
Virtual screen size determined to be 640 x 480
Considering that without Option "UseEDID" "FALSE", we get:
Virtual screen size determined to be 1280 x 800

Also, this:
Unable to get display device DFP-0's EDID; cannot compute DPI
And without Option "UseEDID" "False", we get:
DPI set to (40, 45); computed from "UseEdidDpi" X config

And this:
Built-in logo is bigger than the screen. I suppose is because of the Virtual screen size being determined to be 640 x 480.

So, how can we have the Virtual screen size determined to be 2560 x 1600?

tredegar · 08-05-2007, 05:59 AM

Edit: I think the virtual screen size is 2600x1600, but the real screensize is 640 x 480. Can you scroll around your big virtual screen (ie have a 640 x 480 window onto the 2600x1600 screen?) /Edit

Quote:

I wish I knew. "Virtual screens", seem to be a pain. The nvidia documentation refers to these in relation to "Twinview" (2 screens at once, don't even start on that!). What we want is for it to realise that the real screen size is 2560x1600, and that the "virtual screen" size is the same.

Otherwise the only potentially useful option that I can find might be:
Option "ModeValidation" "NoVirtualSizeCheck"
And that goes in "Section Device"

Quote:

(WW) NVIDIA(0): No valid modes for "2560x1600@60i"; removing.

This is really annoying, because we have computed the interlaced modeline and listed it.
I suppose the name of the resolution we want "2560x1600@60i" is exactly the same in both the places it is mentioned (ModeLine and Modes)?
You might try putting that modeline (ModeLine "2560x1600@60i" 163.70 2560 2592 3208 3240 1600 1636 1644 1681 interlace) into the Subsection Display beneath the line that says
Modes "2560x1600@60i" "1280x800" "1280x768" "1200x800" "1024x768" "800x600" instead of (or as well as?) where it is now, (in the section Monitor)

Oh. It didn't like it there then.

We won't try that again.

I have (another) question for you. How is the monitor connected to your PC?
From the NVIDIA documentation:

Quote:

NOTE: anything attached to a 15 pin VGA connector is regarded by the driver as a CRT. "DFP" should only be used to refer to digital flat panels connected via a DVI port.

Your monitor seems to be detected as DFP. Are you using a DVI port?( I don't know what these are).
Meanwhile, let's try this:

Quote:

"NoDFPNativeResolutionCheck": when validating for a DFP, a mode's size is validated against the native resolution of the DFP; this argument disables this stage of the mode validation pipeline.

It goes like this: Option "ModeValidation" "NoDFPNativeResolutionCheck" in the "Device" section like this:

Code:

Section "Device"
    Identifier     "NVIDIA Corporation NVIDIA Default Card"
    Driver         "nvidia"
    Option         "ModeValidation" "NoDFPNativeResolutionCheck"
EndSection

Try this in "my" xorg.conf, exactly as posted earlier. We are trying to change one thing at a time here.

Yes. My graphics card has two DVI ports and my monitor only has DVI (no option for VGA like on most of the LCD monitors).

I'm not really sure what you mean. When I played around with the nvidia-settings GUI, I was able to get it to show something like a 640x480 window on a 2560x1600 screen. When I applied the changes, I had pretty much the same resolution as now, but I could (had to) scroll to view my entire desktop. My monitor was only displaying a quarter of the viewable area, but using all 30" to do so.

tredegar · 08-06-2007, 04:40 AM

Maybe it is time to start trying multiple options.
Try these modifications to the usual xorg.conf:

Code:

Section "Monitor"
    Identifier     "UP-M30W1"
    Option         "DPMS"
    HorizSync      30-80

    DisplaySize    800 450
    Modeline       "2560x1600@60i" 163.70 2560 2592 3208 3240 1600 1636 1644 1681 interlace
    Modeline       "1280x800" 85.64 1280 1312 1632 1664 800 816 824 841
EndSection

Section "Device"
    Identifier     "NVIDIA Corporation NVIDIA Default Card"
    Driver         "nvidia"
    Option         "UseEDID" "False"
    Option         "ModeValidation" "NoMaxPClkCheck, NoEdidMaxPClkCheck, NoVirtualSizeCheck, NoDFPNativeResolutionCheck"
EndSection

Section "Screen"
    Identifier     "Default Screen"
    Device         "NVIDIA Corporation NVIDIA Default Card"
    Monitor        "UP-M30W1"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
        Modes      "2560x1600@60i" "1280x800" "1024x768" 
    EndSubSection
EndSection

Notes:
I have added a modeline for 1280 x 800, this doesn't need interlace, so it might be interesting to see how this is handled.
The option Modevalidation is followed by quotes containing 4 comma-separated options.
Please startx with verbose error reporting startx -- -logverbose 6 and we'll see what it says.

Is there anything to be gained from plugging your monitor into the other output of your videocard?

I don't know if it means anything, but this is still there:

Could not init font path element /usr/share/fonts/X11/OTF, removing from list!
Could not init font path element /usr/share/fonts/X11/CID/, removing from list!

And back to no valid modes for 2560x1600, so it appears that the answer might lie within the "useEDID" option...

I liked that bit too

! But then it threw it all away with

Code:

(WW) NVIDIA(0): Unable to use mode "2560x1600@60i" for DFP-0; cannot compute
(WW) NVIDIA(0):     backend DFP timings (mode is larger than native backend
(WW) NVIDIA(0):     640 x 480).

A google search for "cannot compute backend DFP timings" returned nothing relevant.
Where is it getting 640x480 from? Not EDID (because it's disabled).

SO, it'll recognise "2560x1600@60i" if we ignore the EDID, and provide the other information ourselves, but I cannot find an option to tell X/nvidia that it's OK to use your DFP at that resolution. Something like Option "NativeBackEnd" "2560x1600" would be nice, but I can't find it. Do you think that would be worth a (mad and desparate) try? I bet it fails with "Invalid option".

My last(?) line of reasoning goes like this: X is misinterpreting the EDID information from your monitor, or your monitor is giving bad information (which windows is presumably just ignoring) and refusing to work. There's an option to read the EDID, not from the monitor itself, but from a local bin file, so maybe we could hack one. Wikipedia has quite a lot of information on the EDID data structure. Perhaps we can create an EDID file that X will work with - Ie one that says

Code:

EDID Name             : UPV UP-M30W1
     Minimum HorizSync     : 30.000 kHz
     Maximum HorizSync     : 80.000 kHz
     Minimum VertRefresh   : 59 Hz
     Maximum VertRefresh   : 61 Hz
     Maximum PixelClock    : 268.500 MHz
     Maximum Width         : 2560 pixels
     Maximum Height        : 1600 pixels
     Preferred Width       : 2560 pixels
     Preferred Height      : 1600 pixels
     Preferred VertRefresh : 60 Hz
     Physical Width        : 800 mm
     Physical Height       : 450 mm

Is there any way you can get me a (Hex) listing of the EDID data from your monitor as it is now, a bit like the stuff in post #3, but not prettified / decoded. Maybe the xlog, at maximum verbosity? Or an option to whatever you used to get that prettified listing? That would be really useful to me. Edit: Update: this info is already in your post #26. thanks /Edit

I have done a lot of searches for your monitor. It doesn't seem popular, and nobody is using it with linux (I wonder why?). I wanted a PDF manual for it. No joy as the (few) links are in ?Korean. But take a look at it yourself: Does it have a "Setup" menu or something, where we can maybe set its default resolution to 2560x1600? And then try again using EDID?

You can safely ignore the fonts errors, & can sort them out (if you can be bothered, they're harmless) when we eventually get this thing going.

I didn't think using the other port conector would help, but ....

I'm off to Wikipedia. I may be some time.

tredegar · 08-07-2007, 03:45 AM

Back from wikipedia, and all over the net. EDID is a headache, but your monitor is not the only one causing problems!

I copied the hex EDID data from your verbose x.log into khexedit and saved the file as EDID.dat
I found a windows-only (2K, XP) EDID editor called Phoenix. Then I found a windows computer, installed Phoenix and gave it the EDID.dat file.
It said "Invalid File" "OK" (Don't you just love windows?)
I re-checked the Hex strings, they are correct. I can't be bothered to check the checksum (Last byte of EDID, makes SUM of all 128 bytes MODULO 256 = 0), but maybe that is wrong. It'll be tedious to compute manually and I'm not starting writing C programs, sorry.

It turns out that there is another way to get the EDID data: Fire up nvidia-settings. In the left pane, click on your Display. Then in the right pane, click on Acquire EDID, and save it as edid.bin. Then please email it to me (Click on my name at the left of this post, Choose email tredegar). Or just check the file manually against the hex dump in post #26, and tell me if they are the same.

You will find this post (and the posts it links to) interesting:

It sounds like a good idea. You've sure done a lot of research for this. I'm still trying to wrap my head around it all... I'm still trying to figure out VIM!

Anyway, as far as the monitor goes, AFAIK, it's only available in Korea and the company has no plans to export. It's a nice monitor though - I've had this one for about a year - the newer ones have quite nice specs, like 1000:1 contrast ratio and 8ms refresh rate. For a 30" monitor, with aluminum housing, the price (under US$1000) is great. But, it's only in Korea...
