I’m currently using the cuda version 4.2 but I need to change it to 3.1. Is it possible to uninstall the current version (ver 4.2) and then install the previous version (ver 3.1) ?

EDIT : Please refer that my os system is linux ubuntu 10.04 64bit.

EDIT : I found how to get the version of 3.1. I have to send e-mail to “devzoneupdate@nvidia.com” to request this old version. Now, please let me know how to uninstall 4.2 then install 3.1.

EDIT : I downloaded cuda 3.1 by request to nvidia, then installed toolkit and SDK. When install the cuda 3.1 toolkit there comes the question about uninstallation of current version. For SDK, we can just delete ~/NVIDIA_GPU_Computing_SDK directory directly for the uninstallation of it. After deleting I could install the cuda 3.1 SDK. I’m done, thanks all.

    Yes, you can easily downgrade the CUDA version provided you aren’t using the CUDA toolkit functions which are only present in version greater than 3.1.

    Also you would have to modify your project settings to use CUDA Rules version 3.1.
