However, what you're describing sounds more like an issue with your distribution than with PyCUDA. If you could find out somehow what packages were installed and uninstalled along with PyCUDA, someone on the list *may* be able to point you in the right direction. HTH, Andreas Dear Both, I am running pycuda on an up-to-date Slackware distribution on an Optimus laptop (Lenovo Y470) with a gt550m. All works very well here. I am using bumblebee and the "optirun" command. The most common problem people tend to face with their respective Linux distributions is that the cuda drivers (SDK) have traditionally been very picky about which version of GCC they support. Most modern Linux distros will install some version of GCC 4.8 or perhaps even later, but CUDA on Linux afaik currently only supports 4.7 and maybe 4.6, depending on the cuda version installed.
