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 am I missing?

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.

[CentOS] Widescreen monitor won't configure to a wide screen

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.

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. Yoik. mhr

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: # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 1.0 (buildmeister at builder63) Mon May 19 00:33:37 PDT 2008 # Xorg configuration created by pyxf86config Section "ServerLayout" Identifier "Default Layout" Screen 0 "Screen0" 0 0 InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/input/mice" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 30.0 - 110.0 VertRefresh 50.0 - 150.0 Option "DPMS" EndSection Section "Device" Identifier "Videocard0" Driver "nvidia" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection
