Since the Nvidia 260 graphics card driver was installed on KUbuntu10.10 yesterday, C + A + FN cannot start the tty terminal. To be accurate, it is a black screen, and nothing can be displayed, but it can be operated. you can log on blindly. After switching back to X, run the w command to check that the system has logged on. It should be caused by terminal resolution or other video card problems. I have no clue. There is no way to go to Google. Many people have seen this problem in the Ubuntu Forum. After analysis, I think the following method is more reliable: nv

It should be caused by terminal resolution or other video card problems. I have no clue. There is no way to go to Google. Many people have seen this problem in the Ubuntu Forum. After analysis, I think the following method is more reliable:

Nvidia graphics card:
Modify/etc/initramfs-tools/modules
Join
Fbcon
Vesafb
Nvidiafb three rows
Modify the/etc/modprobe. d/blacklist-framebuffer file.
Comment out three lines, namely diafb, vesafb, and vga16fb.
Run sudo update-initramfs-u to restart the computer.

My vga16fb line is ignored.
In addition, I thought it may also be a resolution problem, so I added a parameter to GRUB_CMDLINE_LINUX = "" in/etc/default/grub and changed it to GRUB_CMDLINE_LINUX = "vga = 792 ", 792 represents the hexadecimal 0x0318 code of the 1024*768 resolution.
Then update grub: update-grub and restart.
If you do not have time to log on to X, you can directly press C + A + F1. Two seconds later, the familiar tty login interface came back! Haha!
