Gnome crash after cuda 8.0 installation via dnf
Yesterday, I decided to use PyTorch as my new deep learning framework.
After installation, I tried to run a program containing this flag:
CUDAVISIBLEDEVICES=0
But the program was not able to detect my GPU (nvidia Titan X) while I had no problem using my GPU with CUDA 7.5 in other frameworks (e.g. Caffe).
So, I tried to check the cuda activation in Python (anaconda) and realize that after "import torch" instruction, the answer to
torch.cuda.is_available() was FALSE.
After some investigations, I realized that the reason is maybe my Cuda version (7.5) So, I tried to install Cuda 8.0 by nvidia rpm file.
After cuda installation there was no improvement while the result of
nvcc --version was again Cuda 7.5.
So, I tried to install Cuda 8.0 directly from dnf. After that,
nvcc --version answer was Cuda 8.0 :)
But I still was unable to detect my GPU in Python (torch.cuda.is_available() was FALSE)
I thought that I should restart my system to finalize the changes.
After the restart, Gnome (I use Fedora 23) cannot be successfully loaded and my screen is blinking at " Starting Gnome Display Manager ..." boot step.
Any help will be appreciated.
