I followed everything as instructed on [https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#abstract](https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#abstract) but I am unable to complete post-installation actions.

You followed everything as instructed? Because Linux Mint isn’t a supported OS. Which part of the instructions were you following that indicated that Linux Mint is OK? ---

According to table 1, Ubuntu 18.04 GCC 7.3.0 Kernel Module 4.15.0 is supported, right? Also, I saw a video ([CUDA 9.0 installation in Ubuntu 16.4 + / Linux Mint - Full instruction with verification - YouTube](https://www.youtube.com/watch?v=FK1y7XQuhp0&t=319s)) yesterday which explains the steps in more detail and found the solution to my problem. $./deviceQuery CUDA Device Query (Runtime API) version (CUDART static linking) Detected 1 CUDA Capable device(s) Device 0: “GeForce 840M” CUDA Driver Version / Runtime Version 10.0 / 10.0 CUDA Capability Major/Minor version number: 5.0 Total amount of global memory: 4046 MBytes (4242604032 bytes) ( 3) Multiprocessors, (128) CUDA Cores/MP: 384 CUDA Cores GPU Max Clock rate: 1124 MHz (1.12 GHz) Memory Clock rate: 900 Mhz Memory Bus Width: 64-bit L2 Cache Size: 1048576 bytes Maximum Texture Dimension Size (x,y,z) 1D=(65536), 2D=(65536, 65536), 3D=(4096, 4096, 4096) Maximum Layered 1D Texture Size, (num) layers 1D=(16384), 2048 layers Maximum Layered 2D Texture Size, (num) layers 2D=(16384, 16384), 2048 layers Total amount of constant memory: 65536 bytes Total amount of shared memory per block: 49152 bytes Total number of registers available per block: 65536 Warp size: 32 Maximum number of threads per multiprocessor: 2048 Maximum number of threads per block: 1024 Max dimension size of a thread block (x,y,z): (1024, 1024, 64) Max dimension size of a grid size (x,y,z): (2147483647, 65535, 65535) Maximum memory pitch: 2147483647 bytes Texture alignment: 512 bytes Concurrent copy and kernel execution: Yes with 1 copy engine(s) Run time limit on kernels: Yes Integrated GPU sharing Host Memory: No Support host page-locked memory mapping: Yes Alignment requirement for Surfaces: Yes Device has ECC support: Disabled Device supports Unified Addressing (UVA): Yes Device supports Compute Preemption: No Supports Cooperative Kernel Launch: No Supports MultiDevice Co-op Kernel Launch: No Device PCI Domain ID / Bus ID / location ID: 0 / 3 / 0 Compute Mode: \< Default (multiple host threads can use ::cudaSetDevice() with device simultaneously) \> deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 10.0, CUDA Runtime Version = 10.0, NumDevs = 1 Result = PASS
