I have remote server running under CentOS 7, usually it's enough to operate using SSH CLI - but sometimes I need a graphic access, so I installed Gnome Desktop there too.
But how to stop or start Gnome Desktop ? Especially because gnome-shell eats CPU when I don't need Gnome.
It seems strange but 3 pages of Google search did not help. I'm afraid there are no a simple solution here like
service gnome stop | start
So thanks in advance for any hint or howto !
But the solution was simple. First of all - check if you GDM service is running.
service gdm status
If not - start it to make active. (my case service gdm was loaded but inactive and it causes a confusing) After that I just stopped gdm service
service gdm stop
and checked any Gnome processes
ps aux | grep gnome
an output is empty, Gnome desktop gone until started again by
service gdm start
