Thank you, and Hello Danleff,
I actually merely downloaded (and after many times remembering that it might be risky, and NOT enabling) the NVidia proprietary driver, I believe from the kubuntu (ubuntu) repository.
After I forgot my concerns for one short second, and "Enabled" it in the section controlling the non-free drivers, I lost it all when I rebooted.
I do have a ubuntu bootable disk that I can use to look at the HDD directories, but the system will not let me change anything.
It appears that, IF I could, - changing the xorg.conf.1 file back to xorg.conf would make this boot as it used to. The system will not allow me to do that, whether I boot to the ubuntu CD, or boot the kubuntu into recovery mode and use the terminal.
The system has kubuntu V7.10 installed.
