The graphic drivers module seems to be properly loaded, but X rendering seems to fallback to LLVMpipe. This was the case immediately after the install. The performance of the SW rendering improved significantly after the first update with the latest packages. $ glxinfo | grep "OpenGL" OpenGL vendor string: VMware, Inc.
