Thanks for reply,I have tried NVIDIA driver 450.51,450.57 and 450.66,but didn’t work.
I install those drivers with the guide:
sudo ./NVIDIA-Linux-x86_64-450.51.run and set the environment variable INDIVIDUAL_DECODER_SCHEDULING to True.
I have the opengl,but when I run the test code in /opt/nvidia/deepstream/deepstream-5.0/sample/configs/deepstream
deepstream-app -c source4....txt
libEGL warning: DRI2: failed to authenticate .I have solved this problem in another PC with 2080ti,by install the driver in cuda_10.2.89_440.33.01.linux.run.I found an available dirver in this runfile,when I replace the driver without any other operations,it works.
But when I try it on the T4,it doesn’t work.
I notice with
sudo nvidia-xconfig --query-gpu-info ,the Number of display devices is 0,does it matters?
