nvidia driver mess up display at logout

[parj]

I have just upgraded to nvidia driver and when I log in to to console the display is all messed up. I have knoppix 4 hd install. My video card is GeForce2 MX 100/200. I do not have problem logging in to kde and I have 3D acceleration enabled and usuable. My problem is how to login to console.

Here's what I did:
1. Installed nvidia driver as per procedure in http://tinyplanet.ca/~lsorense/debia...-dri-howto.txt
2. Installation OK - no errors
3. Reboot - unable to start X , console only
Error : X is not executable
messed up symlink: /etc/X11/X -> /usr/bin/X11/xfree86
fixed : /etc/X11/X -> /usr/x11r6/bin/xorg
edit xorg.conf device section:
changed Driver from "nv" to "nvidia"
commented:
# Load "GLcore"
# Load "dri"
4. Reboot - OK now, nvidia logo, kde login prompt, kde gui
5. test: glxinfo - OK
6. started torcs - OK
7. logout to restart computer again just to make sure
screen messed up, no text just green color blocks
8. computer restarted - start up screen OK
9. selected login to console at login prompt
screem messed up again
login blindly (blindly since I cannot see any text)
typed clear and now screen is blank
typed startx and I'm back to kde login prompt
logged in normally to kde
10.pressed ALT+CTRL+BACKSPACE - back to messed up screen

IMO this is caused by nvidia driver. if I revert back using nv as driver everything is OK.
I have noticed that using "nv" driver is using xf86Config-4 and X executable while "nvidia" driver uses xorg.conf and xorg executable.
Can anyone shed light on this?
I cannot login to console without modifying xorg.conf to revert to nv driver. I've been seaching the web to 2 days now and I seem not been able to find explaination to this.

Here's the portion of my xorg.0.log - I included only the warning. Did not get any error.

i had been using knoppix since 3.6 for about a year now and I found most solution to problem I encountered in this forum. Only this time I'm stuck after almost 2 days of searching.
I found mostly problems of staring X after upgrading to nvidia driver. My problem is how to login to console.
Any help is highly appreciated regarding this issue.

Thank you.

This is had been resolved about 7 months months ago but I have forgotten it. I've seen that more than 400 have viewed this post. It seem to me that a lot of people are having this problem.

This is actually a hardware problem. In my case this was due to the modulator that I use to connect to videoout to connect to a TV. There was a 75ohms resistor connect at the video input of the modulator which seems to affect the video card.

The simplest solution is to disconnect the modulator when running knoppix. When connecting directly to TV videoin, this issue occurs on some set but not to other.

Hope this may be helpful.

I have just upgraded to knoppix 5.0.1 and able to install nvidia driver again in this new setup.
