TNT 2 broken under Ubuntu
I spent past 20 hours searching for a way to use Nvidia driver version 7174 under Ubuntu.

My card is TNT 2, my system is Ubuntu Breezy Badger with 2.6.12-9-k7 kernel.

I did pretty much everything that I could find on Google, and the card still does not work.

What happens is: when I turn on kdm or run startx the screen goes blank, blinks once (as if from changing resolution) and then the whole system hangs.

I installed the driver from the legacy package, provided correct kernel headers, used correct version of the GCC. The nodes in /dev/nvidia[0-7] and /dev/nvidiactl are being created correctly (when I create them manually, it makes no difference). When I do "modprobe nvidia" it loads cleanly, I do not have any nvidia framebuffer modules loaded.

I use an xorg.conf that worked with my previous sytem (but with 2.4 kernel), so that's not the problem either.

I did about a hundred different things that were supposed to help, according to posts from different forums (uninstalled udev, commented out glx in xorg.conf, and many more I don't remember), and have lost all hope of making this work.

Does anyone have any ideas?

Thank you in advance for your help.

Re: TNT 2 broken under Ubuntu
you need legacy drivers...

sudo apt-get install nvidia-glx-legacy

oh wopsy uhh im not sure..

Re: TNT 2 broken under Ubuntu
These are legacy drivers. The latest and the only ones that work nicely with kernel 2.6. I don't think that they are the problem - unlike all the other drivers (yup, I tried about 10 different versions, just in case), they compile nicely and the module loads without a glitch.

In one forum somewhere I found an advice that installing these from Nvidias package is a better way to get the card to work, than using Ubuntu's packages.

Re: TNT 2 broken under Ubuntu
why dont you just use the defaults? what do you really need the drivers for? the nv driver should be fine... Your not expecting good 3d?

Re: TNT 2 broken under Ubuntu
No, I'm not expecting to play 3d games on that. I would however like to watch some movies, and nvidia drivers make scaling much easier on the cpu.

Re: TNT 2 broken under Ubuntu
GRZEBO, I had the problem you had with my TNT card and the problem is cased by the default color depth and resolution settings in xorg.conf. The card does not support the default resolution-colordepth-refresh rate combination.

I set my default settings in the screen section

DefaultDepth 24


DefaultDepth 16

and it all went fine at 1920x1440 on first reboot.

I will now try and play with the modes in the 24 depth subsection and try to see if I can get a 24bit depth at a lower resolution to work.

I will try and let you know about the results. Let me know if this helps

Good luck

Re: TNT 2 broken under Ubuntu
Yup it works if you also change the modes by removing the unsupported display resolutions..

By the way I did not make any changes to any drivers for the card they are the ones in the release cd...
