I have a Dell T7910 workstation with two K6000 GPUs running RHEL 7.0
I previously installed Cuda Toolkit 7. It worked fine. I wanted to install Cuda Toolkit 8.
I tried to uninstall CUDA Toolkit 7 but there was no .pl file in the cuda bin directory. So I tried yum remove cuda, as directed in the instructions, but that failed to uninstall.
I then followed the installation procedure for a network package install for Cuda Toolkit 8. I rebooted and now cannot get Xwindows to work. I can get to the command prompt.
Any ideas how I can get the system running properly again?
Follow the instructions in the linux install guide to remove all old installations. Given that there are two different installation methods, and you haven’t identified how you installed CUDA 7, you’ll need to read and understand the guide.
Once you have all old installations removed, then follow the instructions in the install guide to install CUDA 8.
If the package manager method is giving you trouble, you can try the runfile installer method.
