I have not tried gnome shell 3, but use cinnamon in different distros ” LMDE , debian testing, archlinux ” and cinnamon also freezes. If I work from the kde environment I do not have any problems , I can spend hours working remotely perfectly.
But if I start with cinnamon environment, just five minutes I’m working I’m 30 minutes, I do not get it.
I’ve tried different versions of cinnamon ( 2.0.16 , 2.2.4 and 2.2.5 new ) and all I just have the same problem .
I’m using the latest version of NoMachine 4.4.6 on both computers.
So if you say that gnome shell users have the same problem , cinnamon is a fork of gnome shell , so it seems to be a problem between NoMachine and gnome shell .
Thank You
