Ubuntu – Nvidia-settings error after upgrade to 17.10


Just upgraded to 17.10. I have been using onboard graphics for a while but need to switch to nvidia now to use two external monitors at work. Running nvidia-settings from the command line gives the following error:

ERROR: Unable to find display on any available system

Googling returned a bunch of results from an Arch Linux forum, but nothing Ubuntu-specific for that error message. So here I am! Could anyone suggest steps to debug?

  • OK, so the answer (from Takkat's comment) is that the proprietary Nvidia drivers aren't supported on Wayland, which Ubuntu 17.10 now uses by default. Choosing "Ubuntu on Xorg" from the login screen made everything work again for me - see this answer.
