Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

After upgrade to 12.10 from 12.04, my Ubuntu freeze at black screen, I know because my AMD/ATI driver is broken and need to be reinstall.

But I can not go to tty with Ctrl + Alt + F(1-6) method, so I can not use command line to follow some tutorial around here.

I can login to GRUB, but after tried many way, it still go to freeze black screen.

Is there any way to get tty than ctrl + alt + F?

Thank you.
