    Hi, it looks like it works way better now when we switched from Gnome to XFCE. CPU consumption dropped to 40-60% when !M is in background, which is ok. Thanks for your help.

    No, they are not too big, here they are. The session was like this: I opened !M, connected to the remote cluster, ran paraview (3D data viewer) with vglrun, loaded some data into paraview, manipulated it for a couple of seconds and logged out from the session. CPU usage was about 200%.

    Thanks

    Yes, it looks like a separate issue. The page there says that I should send the logs as an attachment to an email to the support, but I couldn’t find the actual address, could you indicate one? Thank you.

    Thanks, it works for the initial screen.

    However, when I connect to the remote host the CPU usage reaches 200-250% easily even if I run only terminal there. After some time it drops to 30-60% and then oscillates between something like 60 and 250% when I run, say, paraview. Is it supposed to be this way? Typical top -H:
