Several times now, I’ve experienced random “unspecified launch failure” errors in well-tested CUDA code right after installing other (unrelated) software on my Fedora machine. The problems disappear immediately if I reinstall the nvidia driver. When I do that, the installer says that my previous driver has been modified since being installed.
Has anyone else experienced this?
I’ve seen the problem with dual 8800 GTX and dual GTX 260 configurations, both with Fedora 8.
