Running NoMachine Server 6.6.8 on an NVIDIA Tegra TX2 module (arm64) running Ubuntu 16.04.6 LTS (Linux4Tegra R28 (release), REVISION: 2.1). The same version is running on the client machine, on Kubuntu 18.10. The Tegra board has no display connected, it’s showing a virtual display.
Right after booting the server, NoMachine+XOrg CPU usage seems normal (around 10%). However, after some minutes it starts growing (nxnode.bin takes around 60%, nxcodec.bin takes 88%, Xorg around 30%).
Is there any additional information I could provide to help find the cause of such high CPU usage?
