Slow response from nxserver in conjunction with sddm

[jtschea]

Dear experts,

since the update to version 6.8.1, I am experiencing a really slow response from the NX server running on a headless (e.g. no connected monitor) Ubuntu 18.04 machine. It seems to be related to the display manager (sddm). When I reboot the server computer, sddm is running but without drawing any window decorations like the title bar. In this case the performance is normal. If I restart the nxserver (“sudo systemctl restart nxserver”) the window decorations are drawn again, but than the NX server performance is really slow.  Also running “glxgears” are showing a frame rate of just 5 fps.

Please find attached the nx logs as tarball.

Does anyone have a solution for that?

Thanks in advance and best regards, Jupp 🙂

Would you change /usr/NX/etc/node.cfg in order not to delete old session files

SessionLogClean 0

retry the two cases and send us the new set of NoMachine log files?
