    Hello,

    We have the phenomenon that the temperature of the GPU increases up to 30° when connecting from a Windows client to a Linux client (CentOS 7.10), even if you do nothing on the Linux machine. When you disconnect again, the temperature stays that high. When I restart the nxserver on the Linux side the temperature will normalize again until someone reconnects. The graphics cards are NVidia K4000 and K4200. Is there a way to prevent this with a setting?

    Kind regards

    Walter

    Hi Walter,

    please show us the output of these three commands:

    nvidia-smi --query-gpu=timestamp,temperature.gpu,utilization.gpu,utilization.memory,memory.total,memory.free,memory.used --format=csv -l 1
    
    nvidia-smi --query-compute-apps=timestamp,process_name,pid,used_memory --format=csv -l 1
    
    nvidia-smi --query-accounted-apps=timestamp,pid,gpu_util,mem_util,time --format=csv -l 1

    Run each the command, reproduce the issue with high GPU temperature, the collect the output.

    Also gather logs from the linux machine as shown in https://www.nomachine.com/AR10K00697.

    The other two commands produce no output
