I'm new to Ubuntu, I recently installed 12.04.4 LTS.
My display is not recognized by Ubuntu.
Display: Kent Modular Electronics (KME) 29LR1901A51UN/1 connected via RGBHV BNC connectors.
Video card: Nvidia GeForce 7600 GT
Under windows I'm using 1280x1024.
I tried different drivers using 'Additional drivers (jockey-kde / jockey-gtk), right now using nvidia_304.116 via jockey-gtk: 'This driver is activated but not currently in use.' Trying different drivers doesn't yield different resolutions, and in Displays my screen doesn't get recognized. Display Unknown.
Via https://wiki.ubuntu.com/X/Config/Resolution I tried 'Adding undetected resolutions'.
$ cvt 1280 1024
# 1280x1024 59.89 Hz (CVT 1.31M4) hsync: 63.67 kHz; pclk: 109.00 MHz
Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
after which
$ xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
This will add the mode to the list, but as TV-0 disconnected. I'm not able to use the mode.

From here I don't know what I'm supposed to do. Having done this doens't change anything yet. After rebooting this TV-0 mode is lost.
Trying to add the mode:
$ xrandr --addmode TV-0 1280x1024_60.00

Is this wrong?
