I’ve been trying my best to get nvidia-settings to work, as I am trying to optimize my GeForce cards memory frequencies. I am using 7 cards - 6 from Ampere, 1 from Pascal. I’ve looked all over online, and have frequented this forum, in an attempt to figure out how to go about it to no avail.
I am attempting to do most of this work over SSH. I am aiming for headless, because I cannot be physically at the location of the machine frequently.
Using DISPLAY=:0 resulted in “Unable to find display on any available system”. This is after trying SSH forwarding (which resulted in a window that reported nothing but a “Help” and “Quit” button) and after redirecting the Xauthority to the active Xauthority listed in
ps a | grep X.
prime-select nvidia results in;
Error: no integrated GPU detected.
Same applies for intel, on-demand options.
NVIDIA-SMI reports all as normal. Every card is reported and operating as anticipated.
It could be possible that the motherboard I am using (a board typically used for mining, the BTC-T37) could be affecting this, but I do not know. Constant purging and reinstalling later, and I am still at a loss.
