TTY 1-6 not functional in Ubuntu 10.04 LTS


I have a x64 system with Nvidia drivers 195.36.15 which seems unable to yield a console on any of the TTY 1-6 allocations. I believe this to be a native resolution problem, but am unable to find the file(s) in order to edit these parameters. Any help would be greatly appreciated.

What exactly is the problem - you can't access the consoles, or you can access but they are not visible?

If you can't access them, it could be something with your keyboard. ALso note that many distros only enable tty1 when logged in graphically.
Change that in /etc/inittab or somewhere below /etc/event.d/

If they just aren't visible, try changing the "vga=###" option on grubs commandline.

This link sorted it for me.

I wasn't worried about the ugly splash screen as I wasn't using it, but that HOWTO [Alternative 1] also fixed up the VTs so they worked again.

And welcome to LQ!

sorry for the late reply... consoles appear, but with only about 20-25 lines of resolution and, just that, lines. No characters.

If there are no characters, how can you count the lines?

Did you read and perhaps follow, and then apply, the advice in the link I gave you in post #3 ?
If so, what happened?

You are not giving us any useful information, so it is very difficult for us to help you further.

I'm running grub2, so I'm not exactly sure where to enter the vga=xxx parameters. Also, I'm guessing at the number of lines based on current resolution. The lines are at the very top of the screen on each of the TTY consoles and GUI seems to have moved to TTY8 for some reason. As far as /etc/inittab or /etc/event.d/, I haven't gone into those files as yet.

Trying vga=XXX as a kernel boot parameter does not currently work with ubuntu 10.04 and the nvidia module.

That's why I posted the link to the solution that does work in post #3, above.

Open the link and follow the (simple) instructions. It worked for me.

I may have neglected to mention I'm also running an AMD 64 system... however I'll give your link in post #3 a try. Thanks for your indulgence.

Maybe you can explain what your link is trying to do. What I read from the link (how to remove the lame splash screen) and what I read from the OPs post (nothing shows up for text consoles) do not seem to match. If a solution for problem A happens to also solve problem B, I'd like to know about that. If it's true, it would help to say that, or something like "don't worry about it being a solution to the lame splash screen, since it solves other things, too".

When I installed the NVIDIA driver to ubuntu 10.04, it worked OK, but my VT's didn't:
I could type commands, and they'd work, but I couldn't see any text on the screen.

The VTs use the framebuffer (FB). So I searched on ubuntu 10.04 framebuffer nvidia and found that link. Steps three and four of that link set up the uvesafb FB so the FB works correctly with the NVIDIA driver.

Because the splash screen also uses the FB, it looks ugly after the installation of the NVIDIA driver (which somehow breaks the FB). Apparently it looks better when the FB is fixed.

As I said, I don't use the splash screen, but I do use the VTs, which are now working properly.

Hope that makes things clearer.

A step-by-step of Post #3 seemed to do nothing. I haven't had a Ubuntu Splash since resolution changes a while ago, perhaps when I installed my nVidia driver. TTY 1-6 have never worked, but I don't recall attempting such before installing the nVidia driver.

NVidia and TTYs

Bravo! The framebuffer was it. Follow Tredegar's information below to get your TTYs back with NVidia drivers. Great post, thanks.

Anything I should add/remove ?

Many Thanks

This is a perfect example of why Ubuntu and Linux, in general, are wonderful with respect to solving problems. A true community spirit! As far as I can tell, the tutorial is on the mark.
