Hi,
I’m having following problem. I have 4x 3060Ti machine which is intended to work as mining rig. (Ubuntu 20.04 desktop)
All cards are working properly under default settings, but when trying to optimize settings for mining only gpu:0 can be managed.
here is what I do:
nvidia-settings -c :0 -a ‘[gpu:0]/GPUFanControlState=1’
The result is:
Unable to init server: Cannot connect: Connection refused
libEGL warning: DRI2: failed to authenticate
Attribute ‘GPUFanControlState’ (caterpillar:0[gpu:0]) assigned value 1.
Regardless the error this card can be manually overclocked.
when trying same with other card:
nvidia-settings -c :0 -a ‘[gpu:1]/GPUFanControlState=1’
I only get errors:
Unable to init server: Cannot connect: Connection refused
libEGL warning: DRI2: failed to authenticate
I use 460.67 driver, however I tried also older version of the driver and results were same.
