This has nothing to do with PyCUDA; it just means that your CUDA installation is broken. You probably installed your X11/Wayland/Mir GPU driver from a different source than your CUDA driver (such as by running the Nvidia installer on a system that already had the Nvidia driver via the OS). This means that your computer is now in an inconsistent state. Unless you know where to look, a reinstall and, subsequently, sufficient care about what you trust to mess with your software install, might be your best options. Andreas
