Difference between display driver and developer driver

Is there any difference between the display driver and the developer driver for CUDA (3.0) ? They are of the same size

I installed the display driver and I can’t find any libcuda file

Does the order of the installation matter? I normally do driver, toolkit, sdk but a thread in this forum said that it had to be toolkit, driver, sdk since the toolkit overwrites a lib directory and does not have libcuda…

I don’t think the order matters too much, but I usually do driver, toolkit, sdk.

On Ubuntu 10.04, I’m assuming they’re using a stripped down proprietary driver in their repo’s, because it doesn’t work with CUDA. However, the driver from the Developer Zone works.
