I have a nvidia GF MX 400, and I have i am pretty sure correct xorg.conf, and newest drivers installed. My computer displays the GLXgears in the 3d acceleration test, but fails the test anyway. HL1, CS 1.6 work perfectly, but CSS just displays a black screen, I bet it has to do with this, and here is my xorg.conf (even though it says xf86 at the top, it is xorg.conf, I am sure.)

# To customise the XKB settings to suit your keyboard, modify the

# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"

# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"

# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"

what should I change, if anything?

Hi,

Though I am not too sure about this.

You should also remove the following lines:

Load "dri"
Load "GLcore"

if they exist

Go to the NVIDIA site and read the installation instructions. I think they have a very good README file somewhere.

Hope this helps.

did that, but now i have other problems.

Then put them back.

If I remember correctly, you're supposed to remove/comment out DRI when using the nVidia driver. I've changed to ATi, so I'm not sure if my memory is serving me. I don't know if you're supposed to remove GLcore.

i did, but no go with 3D acceleration, followed the tutorial on this site.
