How can you turn off graphics at Ubuntu's GRUB -bootloader such that you can access and see terminal?

I have a 5-year-old Nvidia graphics-card which is not anymore compatible with Linux kernel 2..18 nor 2..14. The problem started after updating the kernel.

I have tried to solve the problem by going to the recovery mode at the GRUB loader.

Everything works except that I can see nothing what is going on. I can login, set my password and then routinely start up Apache server such that I can see my internet site served.

However, I would like to see at least letters. I am not interested in graphics.

You shouldn't directly delete files from the /etc/rcn.d directories as RageZ has said - you should use the update-rc.d script to manage what starts and what does not.

If you use :

update-rc.d gdm remove

That will stop Ubuntu from attempting to start the Display Manager by default, and should leave you with a nice text prompt.

Using Control+Alt+F1 should work too even if GDM has started already - but sometimes if the drivers are particularly broken, it leaves the graphics card in a state where it can no longer switch modes properly, so removing GDM from the startup is probably a better alternative.

I am not sure what window manager you are using but if you are using gnome in console do this

sudo rm /etc/rc2.d/S13gdm

and reboot the machine, this command would prevent X from starting up.

Also you should be able to get a console by pressing Control + Alt + F1.

You can force the system to boot in runlevel 1, which will give you a plain text console. At that point you can use the other hints to disable gdm so the next full boot will also result in a text console.

In grub press 'e' and edit the kernel line to add 'single' and hit 'b' to boot.

Remove the nvidia xorg driver and drop back to the nv driver.
