Can you disassemble that screen, so we will know what LCD interface it has?
I've taken a few photos of the innards of the display. The controller appears to be a MSTAR MST703-LF. There are two connectors on the board - a 4 pin (+12v, composite input 1, composite input 2, ground) connector for the external power and signal cables and a ZIF ribbon connector for the panel/backlight assembly.

Are there any tips for getting a composite signal out of a laptop when running Linux?
Are you asking how to enable composite output under Linux, or can you already output a composite signal and just want tips for a clearer display?
If the former, it will depend on your video hardware. In the past, I've had graphics cards that:
• always output a composite signal displaying the contents of the primary framebuffer
• output a composite signal after being enabled using a manufacturer-supplied utility (usually Windows-based, but the hardware setting was permanent and persisted across reboots/shutdowns)
• as above, but the setting did not persist across reboots, requiring a Linux-based utility that could be added to the system's init script
• output the contents of a secondary framebuffer that could be accessed using X with the correct drivers
As for a clearer display, if you're using a text console, make sure you're not booting with any of the advanced framebuffer kernel parameters set, to ensure that you get a basic 80x25 character display rather than anything high resolution and fancy.
If you're using X, you might want to try a few of the following resolutions:
Even older hardware should support at least some of those. It's unlikely that a modern desktop environment will allow you to select resolutions that low though, so you may need to add the modes to your X config manually. Something else to look at would be the DPI parameter of the display, also in your X config, which will affect the scaling of text and graphic elements under DPI-aware X applications.
