Nvidia screen resolution size not configured correctly

[nef131]

@nef131

First, thank you to all you for attempting to help me.

On examining the GUI for nvidia-settings (i.e. the program that appears in the Kicker menu as Nvidia Server Settings), I notice that on the “tab” X Server Display Configurations, there are alternative settings, one for the Samsung SyncMaster (DFP-0) - which is what appears to be enabled - and another for X Screen 0. Samsung SyncMaster appears, in the graphic of the desktop, to be a subset of X Screen 0. The read out for X Screen 0 is 1920x1080 pixels (530x301 millimeters). There appears to be a means to switch between Samsung SyncMaster and X Screen 0.

Is this program functional to make permanent change (or even temporary changes that can be copied into a config file) and, if so, how does one use this?

I played with nvidia-settings, as per my above post. I created - but did not save - a configuration file generated by the program. I would assume that it would be saved to a file to be named xorg.conf, i.e., as /etc/X11/xorg.conf. The preview of the generated file reads (and this is after it corrected what it thought was conflicting information):

Or, would this be saved in my home directory, as /.nvidia-settings-rc and then started by means of a ~/.xinitrc file that includes something like the following code?

nvidia-settings --load-config-only & startkde

I am basing my guesses on this user guide page.

There is a much easier - albeit a bit ugly during bootup - solution. If I set the boot to nomodeset, I boot to 1920x1080. I am going, now, to make this a permanent solution to my problem by adding the setting to grub.

You have to be root to change the xorg.conf file so you have to start the nvidia-setting program as root

Thanks. As I noted, I solved my problem by adding nomodeset to the boot option.
