[Gnome] Nvidia FX5500 refresh rate issue

[Hessesian]

Hi,

I'm running Ubuntu 8.04 Hardy, with gdm, and in nvidia-settings, xorg.conf or any other solution I tryed, I cannot get more than 60Hz resolution @ 1280x960, I'm using nvidia-glx-new driver, before I posted here, I spent hours searching on web to find solution, with no succes, I was following this guide https://help.ubuntu.com/community/Fi...esolutionHowto, searched similiar topics, I found one topic with problem very close to mine, but it was solved by increasing AGP appitude in BIOS from 64 to 128, but in my case using Gigabyte 60XT motherboard with 815EP Intel chipset, I cannot increase it more then 64MB.

Here is my Xorg file:

Thanks for any fast help. Also I notice that nvidia-settings manager will remove metamodes and modes option when I show preview of file that nvidia-settings wants to save to xorg.conf.

Okay, so I managed to force it to 1280x960@70Hz, but there came this problem, on the left side is blank black space about 180-200 pixels width, in windows I have no such empty spot,
So how can I spread screen of another 180 pixels ?

PS: adding string

 Option         "ModeValidation" "NoEdidModes, NoMaxPClkCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoEdidMaxPClkCheck"

in monitor section helped to force it to this resolution

just a guess, somewhere on your monitor there should be some buttons to adjust the image so that it will fill the screen area. I'm using geforce 5500 also and selecting some resolutions makes the screen somewhat distorted so I use the buttons to make it fit the screen area. I dual boot Windows and it doesn't change the Window's setting. Also there's this which might help, following Hobo Joe's advice in thread
http://ubuntuforums.org/showthread.php?t=747371
and using envyng to set up my nvidia card, using "System>Administration>NVIDIA X Server settings" it offered me more options than the default screen resolution settings. This will be good for the session your in however, in order to save the configuration to xorg.conf, you'll have to open a terminal window and launch "gksudo nvidia-settings".

Well that's not quite my problem. My problem ist, that nvidia recognized my monitor, but didn't found right resolutions. I needed to force it to higher refresh rate, with succes as you can see, but after setting new resolution with new refresh rate, the picture is not covering all the screen, and yes, I know about those buttons on my monitor, but in width settings I'm on 100%, in windows I have picture on full size of my monitor at 1280x960@70Hz, in Ubuntu I have this empty spot. So I need to find why it is as it is and how to spread picture on whole screen as I have it in windows.

And I know about nvidia-settings and I ran it with sudo command.
