"During start-up, the system occasionally likes to do a check of its filesystem. Unfortunately, during the check, the screen is blank, apart from a flashing cursor in the in corner. There should be some indication of what's going on, as it looks as though the computer has crashed during start-up."
No, it's a known problem in Ubuntu 7.10. You wrote:
"During boot-up and shutdown, Ubuntu selected a screen mode that resulted in the monitor shutting off. I've been able to resolve this by editing some GRUB configuration files."
I can only guess, but most probably you've added the "vga=" parameter to the kernel line in GRUB's menu.lst file. This results in an attempt to use the so-called framebuffer. Unfortunately in Ubuntu 7.10 all framefuffer drivers have been disabled (blacklisted) because of the interference with power management. Yes, it shouldn't happedned but it did.

You may want to follow a rather simple procedure to enable the "vesafb" framebuffer driver and get the "vga=" working as expected:
