Comment 28 for bug 1758243

Btw, I've tried to follow this guide (among others) which seems quite complex but is is a complete no-go for me: https://float-middle.com/ubuntu-18-04-steam-and-nvidia-390/

Also tested this on a more recent device (mine is about a year old) with Nvidia GTX 1500 Max-Q also running Ubuntu 18.10 and that was not successful either - so I am more confident this is not a hardware specific issue.
