Monitor Setting

[Guest]

One of the main reasons for installing Kubuntu 12.04.1 to my HDD was that the Live CD offers a monitor setting of 1366x768; Uncommon in distros I came across sofar. However, this setting is definitely not available once Kubuntu is installed. Is it possible to obtain a post-installation 'fix'?

With this being a visual display problem, it might be useful to know what graphics hardware your machine has, and also what type of connection to the TV you are using - VGA, DVI, HDMI, etc.

With this being a visual display problem,...

Well, it's not *really* a problem rather a nusiance since the native resolution of my monitor is 1366x768.
Most importantly, I am surprised that the software settings on the Live CD don't install to the HDD of my desktop computer; Which is the issue I *really* wish to get resolved.
Since the script/program is already written and available on Live CD couldn't the author(s) of the "Size & Orientation" software be persuaded for providing a post-installation fix?

I reluctantly used...
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates && sudo apt-get update && sudo apt-get install nvidia-current nvidia-settings

which installed nVidia driver version 304.64 but the 'Resolution' drop-down menu in 'X Server Display Configuration' is greyed-out and marked 'Off'. When clicking onto the downward-pointing chevron mark the menu doesn't offer my desired monitor setting of 1366x768 not even 1360x768; The closest setting available is 1024x768.
(When clicking onto any setting in 'X Server Display Configuration' the entire "NVIDIA X Server Settings" window will just close and a 'crash' notification will pop up).
However, (after installing the nVidia driver) in 'System Settings' ==> 'Display and Monitor' ==> 'Size and Orientation' the setting 1360x768 is available and working.

My 32" LCD (TV) monitor is exclusively used for the Internet and is not connected to any satellite, cable or free-to-air TV network etc.. The connection between computer and (TV) monitor is a common VGA cable. Cheers...
