I've been searching across forums for days now, and usually I receive no replies. If any of you can solve this problem, I will be eternally grateful. I'm going to try to be as descriptive as possible.
What I have:
* Ubuntu 6.10 "Edgy Eft" running the default GNOME
* Gainax Geforce 5600 FX 256MB Video Card
* Starlogic 20.1" Widescreen LCD, plugged in with a 10-foot DVI cable (yes there is a DVI input)
* 1GB of RAM
* Athlon XP 2800+ (it's old, and would probably be called a "Sempron" by the new standards)
* nvidia-glx (Nvidia driver) installed from Synaptic Package Manager
What I'm trying to do:
Run the monitor at 1680x1050 resolution, with a refresh rate specifically of 60Hz (and no higher). I haven't been able to get above 1280x1024 yet.
My xorg.conf (modified by the help of a Linux guru friend of mine):
See attached file (below, in next post).
What I've tried to do:
My friend and I added the two modelines that you'll see in the xorg.conf file, but neither one worked.
It just reverted to either 1280x1024, or in some cases, 1024x768 (gross).
I also tried running "sudo dpkg-reconfigure xserver-xorg", but when I get to the point where it allows me to select resolutions/refresh rates,
the only option even close is "1680x1050@75Hz"; however, my monitor can only sustain 60Hz at that resolution.
Specs, direct from my monitor manual:

You are pretty much on your own and nVidia support with proprietary driver.
Usually dropping all "modelines" and "modes" from xorg.conf , or even removing file itself are best ways to determine what goes wrong.
Please add /var/log/Xorg.0.log from an Xorg startup - failed or succeded - with xorg.conf moved out of the way.
nv driver detects DVI displays at full resolution.
I'm not sure what you want me to do, but here's my Xorg.0.log file:
http://www.ee-stuff.com/Ex
(--) NVIDIA(0): Connected display device(s) on GeForce FX 5600 at PCI:2:0:0:
(--) NVIDIA(0): NVIDIA TV Encoder (TV-0)
(--) NVIDIA(0): TPE LCD MONITOR (DFP-0)
(--) NVIDIA(0): NVIDIA TV Encoder (TV-0): 400.0 MHz maximum pixel clock
(--) NVIDIA(0): TV encoder: NVIDIA
so it falls back to weakest - television output.
Hi,
I had a look at your xorg.conf and the LCD spec. This is what I would suggest:
1) You are currently not using the NVidia driver. I would suggest you to use the NVidia driver. The instruction is here: http://ubuntuguide.org/wik
2) Use the specification in the PDF to generate your modeline via http://xtiming.sourceforge
Modeline "1680x945@60" 134.32 1680 1712 2216 2248 945 964 973 993
3) Remove the other modelines from your xorg.conf and put in the above modeline, then in the "Screen" section just use Mode "1680x945@60"
Thanks! I'll try that when I have a chance, hopefully later tonight. Although I think you generated a slightly incorrect Modeline (I had wanted 1680x1050, not 1680x945); I can probably do it myself with the link provided (although I'd feel safer having you do it!). And I did see the Nvidia logo every time X started up, *just* prior to the log-in screen. Doesn't that suggest that I was, in fact, using the driver? In any case, I'll take a look at those tutorials you linked to...
@slyong: I tried the modeline you just provided, and it still failed and went into 1024x768. Here is what I changed my xorg.conf file to just before restarting X, and then what xorg.0.log ended up with:

@gheist:
I tried changing the xorg.conf file that I just included (the second one) to load the "nv" driver instead of the "nvidia" driver, and it started up in 640x480. (ouch) I quickly switched back to the nvidia driver, and am running in 1280x1024 again. I would really like to use my monitor to its full potential, though, so that it isn't stretching the image from a 4:3 resolution onto a 16:10 display!
Here's the output from xorg.0.log with my attempt at the "nv" driver:
http://www.ee-stuff.com/Ex
NV driver will not work at full resolution, because it uses VESA BIOS on card to set modes.
NV driver has an option "FPScale" which disables stretching lower resolutions (read "man nv" on your system)
Maybe there is some tool to adjust VESA modes in nVidia BIOS to make nv driver happy, i know of one for Intel graphics cards, but that does not fit nVidia for sure. ( look inside your favorite overheating-overclocking-o
Nvidia driver already works at its full power:
6.1 No Warranties. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SOFTWARE IS PROVIDED "AS IS" AND NVIDIA AND ITS SUPPLIERS DISCLAIM ALL WARRANTIES, EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
@slyong: I just tried that modeline, and it fell back to 1024x768 @60Hz. And yes, I recognize that 1680x1050 is not the 16:9 ratio. But then I don't have a 16:9 monitor. As detailed in the specs (PDF, above), this is actually a 16:10 monitor--which is not all that uncommon.
So far all we've done to try and solve this problem is to test out various modelines, which hasn't worked yet and doesn't look promising. I take it, gheist, that by your last comment, you are implying that this question has no solution. =( If that's really the case, then who can I complain to? Nvidia, perhaps? (But if you can figure out some miraculous solution, I'd love to hear it! That's why I asked!)
(II) NV(0): Supported VESA Video Modes:
(II) NV(0): 1280x1024@75Hz
So - try nv driver with flatpanel enabled and not stretched image, without any Modes or ModeLine options.
Driver "nv"
Option "FlatPanel" "true"
Option "FPScale" "false"
Does it show up correctly???
DVI is DIGITAL and it does not care of ANALOGUE PLL used for ANALOGUE display, aka refresh rate.
It seems that NVIDIA driver has some problems around its equivalent of "FPscale" option of nv driver.
I tried that; it reverted to 640x480 @60Hz. Here is the xorg.0.log file that resulted:
http://www.ee-stuff.com/Ex
Is the image stretched or centered ???
Somehow ee-stuff seems down, i will look into your log in couple of days, and suggest options for nVidia driver to make it work.
Years ago i last tried nVidia driver was soo unstable i ended up with nv, and in the end with radeon card, but people say it has improved since.
Next steps without looking at log:
Now try nv driver with Modes "1280x1024" "1024x768" "800x600" "640x480" ( at default resolution, with same FP options, then with FPScale alone )
That is best "nv" can do without editing BIOS.
Tried again, and failed again. Here's another log file to look at. And EE Stuff's been working fine for me lately.

I actually started reading through it myself, and noticed the following:
(II) NV(0): Supported Future Video Modes:
(II) NV(0): #0: hsize: 640 vsize 360 refresh: 70 vid: 51761
(II) NV(0): #1: hsize: 640 vsize 480 refresh: 70 vid: 18993
(II) NV(0): #2: hsize: 800 vsize 600 refresh: 70 vid: 19013
(II) NV(0): #3: hsize: 1024 vsize 768 refresh: 72 vid: 19553
(II) NV(0): #4: hsize: 1280 vsize 1024 refresh: 60 vid: 32897
(II) NV(0): #5: hsize: 1600 vsize 1200 refresh: 60 vid: 16553
(II) NV(0): #6: hsize: 1680 vsize 1050 refresh: 60 vid: 179
Note #6. Does this mean that 1680 x 1050 is a "future" mode, as far as the nv driver is concerned? (i.e. not implemented yet?) If so, I don't think the nv driver is the one to use right now.
Oh, and by the way, I contacted the technical support department of the company that manufactured the monitor, and received several horribly useless replies. First, this one (after very clearly explaining that I used Linux, several times):
...go to Control Panel - Display - Settings tab - Advanced button...
Then, after sending a somewhat agitated response to that, this one:
Contact Linux for further assistance on how to change your video settings.
Thanks a lot, Star Logic. So what that means is that you guys are my only hope! (I could contact Vvidia...but I'm not sure that would bear any fruit, either.)
