I just put a 1680x1050 LCD monitor on my home system, and I went into system-config-display to configure it as such, and it just won't take.
I had to tweak some of the settings by hand, but when I log out, I get the wide screen for both the Nvidia driver splash screen and the login screen.
But, when I log in, It jumps back to 1280x1024 and refuses to run in wide screen mode.
Here's the xorg.conf (even when I'm logged in and the screen is only 1280x1024):

The commented out Horix and Vert syncs are for my old monitor (a 17" non-ws), and the new ones are from the manual for the new screen. I tried with these commented out, but it still would not work.
One thing I noticed is that when the gdm starts up, it goes from "auto adjust" (wide screen) to "analog-d" (non-ws) - dunno what that means.
Any suggestions? It's really annoying to have a wide screen and not be able to use it....
Thanks.

What version centOS, Kernel and nvidia drivers are you using? Also, what brand and model monitor?
I don't have my Samsung wide screen hooked up to my centos, but when I first connected it to my Mandriva system, I could not get the full wide screen. I was planning on upgrading, so I did not fiddle with it much, I figured I would wait to see if the updates in the new Mandriva worked any better. It did, as soon as I upgraded, the Mandriva auto-detected my monitor and all has been fine since.
It may bee you need to upgrade your Nvidia drivers.

I forgot to add to my previous post, that I too have a Samsung monitor. Look into newer drivers for the gfx-card first.

Did you get the latest drivers for your gfx-card from Nvidia?
FWIW, I have a same-rezed monitor as you do, and it works for me, both with CentOS and RHEL3, but I had to download and install the newest proprietary drivers from Nvidia to get that [weird] resolution working.

I am running CentOS 5.2 x86_64, kernel 2.6.18-92.1.6.el5.nx (the nx means this is the stock CentOS 5.2 kernel plus NTFS read/write compiled in), nvidia driver version 173.14.09.
Still does not work. The boot screen, anaconda screens and boot progress screens and the login screen are all 1680x1050. But when I log in, I get the message "analog (d-sub)" fom the monitor, and the gdm screen is 1280x1024, no matter what else I do. My xorg.conf now only has the one mode in it (1680x1050), but that doesn't work, and system-config-display will change it to 1680x1050, but it doesn't stick.
I used to be able to fool s-c-d into using a generic CRT, but that doesn't work any more - ithe LCD 1680x1050 seems to stick, just not GNOME's ability to use it.
There has to be some little thing I'm missing here - is there any old setting file I need to remove or anything like that? I uninstalled the nfidia driver from dkms and removed all related files that I could find.

About that generic CRT, have you by any chance tried generic lcd instead?
Was your system fully updated? Can't recall if you mentioned this. Per chance you're missing some updated gnome-stuff?

Try letting the nvidia installer generate the xorg.conf file (and then possibly tweak it by hand later). Or try the following xorg.conf file which works for me an autodetects any type of display I've attached to my CentOS systems, including wide screens:

I'm not sure if this is related, but compiz won't do large resolutions. I had to switch to metacity to get gnome to run at > 1280x1024. That was on my work laptop running ubuntu, though, so take it with the appropriate grain of salt.

Keep in mind that I'm ignorant.
You had mentioned earlier that it not only changed resolution, but revereted to analog monitor. I don't know if this will help, but have you run kudzu? Check /etc/sysconfig/hwconf. /VIDEO/
You should see your new monitor in there. I don't know enough to know if this has an effect though. I presume that when X terminates, the driver is unloaded. When it starts up again, the driver would be reloaded. I don't know if DDC gets involved here or not.
Check your X logs (/var/log/X.[0-9].log for messages.
Thanks to all so far.

It's only connected via the analog cable. First, outside of GNOME, it works in full wide screen mode, so I don't think that's it, and second, I don't know if there is enough advantage to invest in a DVI cable.
I'll look, though, tonight, when I get a chance.

Based on the comments that get inserted in my xorg.conf file by the nvidia xconfig, I'm guessing no since I have specified the frequency ranges (from the manual), and when I didn't, it still didn't work.
Check your X logs (/var/log/X.[0-9].log for messages.
Good point....

I wonder if this is related to a problem I had, 1 or 2 years ago, where system-config-display (?) said that it was updating xorg.conf, but, in fact, it did not update it. Sometimes the GUIs do not work as advertised. There was some command which ended in --rebuild (?) to generate a completely new xorg.conf file. Possibly that would help you, with part of this problem?

'spossible, but I usually wind up tweaking it by hand 'cuz it needs it AFAICT.
However, to s-c-d's credit, I have checked the output xorg.conf after running it, and the file seems to be set up right, or at least not any more wrong than I would have, and it still doesn't work.
I've had to tweak xorg.conf by hand every time to get it right. Not sure why....

Do you have some setting on your actual monitor-hardware you can tweak? You know how most lcd-monitors have auto-settings enabled. Maybe something there is ducking with your x-configs?
FWIW, I've seen problems when I've had lcd-monitors connected over a kvm-switch and/or monitor-cable extenders. Sometimes the OS just can't correctly identify the monitor and the only way to fix it is to connect the montor directly to the computer at least once to properly identify it.
Also, do you have a way to connect the monitor to a computer running eg Windows, just to see it's CentOS and Gnome that's giving you grief and not the hardware?

I tried that this morning - nothing seems to be relevant. I tried going form "native" to "full screen" but that just widened the 1280x1024 image to fill the screen, which is NOT what I want.

This is my primary workstation - no extra connections at all. My machines are so spread out that a kvm wouldn't work for me anyway, and I'd rather keep mine separate for other reasons.

I can do that, but since it works up to the login in wide screen mode, I'm fairly certain that it is the gdm (GNOME).

Don't have kde, but I do have a live cd and I got a response on the gnome list from Ritz about a setting that might help. I'll find out when I get home, undoubtedly late tonight, as usual.

Ah, right, forgot about that.
Did you ever try with another monitor, but use same settings etc with X? What I'm drifting at here, is to see if the same happens with other monitors in order to make really sure it actually is gdm causing the problem and not your new monitor.
I know you said it works at some points, but we've kinda' come to the road's end, as it were, so trying out even the farfetched solutions etc, would make sense now I think.
