- Check what is using your GPU memory with
sudo fuser -v /dev/nvidia*
The output will be as follows:
USER PID ACCESS COMMAND
/dev/nvidia0: root 10 F...m Xorg user 1025 F...m compiz user 1070 F...m python user 2001 F...m python- kill the PID that you no longer need with
sudo kill -9 <PID>
Example:sudo kill -9 2001
nvidia-smi
NVIDIA System Management Interface program
sudo nvidia-smi --gpu-reset -i 0Go to NVDIA X server settings -> PRIME Profiled -> Turn on NVIDIA (On Demand). I had Performance mode enabled, which caused Xorg and gnome-shell to run on my dgpu and consume around 430mb memory. Be sure to reboot your PC once you set that option.
Although this question is 4yrs old, just leaving my answer here in case anyone finds it helpful.
