My display came up as unclaimed when running
lshw -class display
So I installed nvidia-387 by addding the graphic-drivers ppa, and running
sudo apt install nvidia-387
I did this so I could get HDMI support for an external monitor, but no luck. The card no longer came up as unclaimed but the configuration said:
configuration: driver=nouveau latency=0
To fix this I blacklisted nouveau by following the steps explained in this Stack Exchange answer: HDMI completely broken in Loki? - elementary OS Stack Exchange
This resulted in a black screen at boot, I can Ctrl+F1 to a text terminal, and if I check the configuration, the nvidia driver correctly shows up.
If I run xrander, I get a “Can’t open display” message.
Attached is the nvidia-report-log
Thanks!
