Debian Can't Seem To Switch Back To Text Mode!
I just finished installing Debian 6.0.4 amd64 and ran update-grub in Ubuntu, found Debian fine. But in grub when I enter Debian, it just goes to that shade of purple Ubuntu has by default, and I know it's there because I can type:
shutdown -h now (enter)
And in 30 seconds the computer turns off.
How would I fix this, without turning the gui on?
To disable the kernel mode setting press E in your bootloader's menu to edit the configuration of the current selected OS. Then add nomodeset to the kernel command line (the one beginning with linux /boot/vmlinuz.... and press Ctrl+x to boot the system. This is a one time solution. to give you better help we need to know which video hardware your machine is using.
Intel is the manufacturer of your CPU. If you have such a laptop that means you have the intel HD graphics chip that comes integrated in modern Intel CPUs and a dedicated NVidia video chip. NVidia calls this Optimus Technology. This is currently not supported on Linux from NVidia, but you may have luck to get it running with Bumblebee.
The characters on your screen are nonetheless displayed by your graphics card, and newer versions of the driver for your Intel (i915 driver)and your NVidia (nouveau driver) are using kernel mode setting. That means, as soon those drivers are loaded they try to set a display resolution that is appropriate for your display. That is in some configurations not working correctly, especially when you have an older kernel, like in Debian 6, and newer hardware, like the Intel HD graphics. If you don't need a GUI then just add the nomodeset option permanently to your kernel line for Debian. I am not a Grub user, so I don't know how to do that, but this link may be helps: http://www.dedoimedo.com/computers/grub-2.html
