I am experiencing a rather unusual problem with my CUDA installation on Linux Mint 18.3. After a clean reboot, running deviceQuery as a standard user:
optirun ./deviceQuery returns FAIL, but if I do:
sudo apt install --reinstall libcuda1-390 sudo optirun ./deviceQuery
Then everything works, running
optirun ./deviceQuery again returns PASS.
sudo do that solves the problem (just reinstalling
libcuda1-390 does not help)?
I am using bumblebee to run programs on-demand with the graphics card.
Edit: I am also suspecting the bumblebee installation to be somehow faulty, not CUDA itself.
