Hello,

when I'm running the coder.checkGpuInstall() command, I'm getting the following output.

Because of the "Permission denied" error, I run MATLAB with sudo and I checked the permissons for the 6.4.0 folder. I changed them, so that everyone has access to the corresponding folder. I although checked that the Environment Variables point to the right directories.

After running the gpuDevice command I get the following output:

The operating system of the PC is Ubuntu 16.04 and I have never worked with Linux before. Does anybody have an idea what causes the error?

Thank you very much!

[Niklas Kraft]

The problem was solved by a reinstallation of Ubuntu.

[Lakshay Bhandari]

Did you just reinstall or erase everything and install ubuntu again ?

I have been trying to run this and have all the environment variables pointing to the correct directories.

Can you be more specific and exact in what you did to fix this?

[Niklas Kraft]

Sorry, it's a few month ago I did this.

What I rembember is, that I did a complete reinstallation of Ubuntu. Than I installed the Nvidia drivers, CUDA and MATLAB. After that it worked.
