The instructions below are for Debian. I run LMDE3 with Cinnamon, and I found using the latest CUDA and NVIDIA drivers broke Cinnamon, causing it to run in fall-back mode. This is still not working - the roll-back steps are given below.
- Check that you've got an NVIDIA device
lspci | grep -i nvidia
- Verify your device supports CUDA
- Ensure your drivers are loaded - if not run
sudo apt-get install nvidia-driver nvidia-smi
- Determine your driver version using
nvidia-smi
(in my case 390.87)
