gnome desktop is not working

Question

Gnome desktop is not working for my redhat PC. The version of gnome desktop3 is 3.14.2-2.el7. When I exec ps -A | grep gnome, it returns

2384 ?        00:00:00 gnome-session
2420 ?        00:00:00 gnome-settings-
2452 ?        00:00:00 gnome-shell

When I exec systemctl status gdm -l, it shows gdm is working OK. One problem listed in /var/log/messages is:

gnome-session: gnome-session[2384]: dconf-WARNING: unable to open named profile (gdm): using the null configuration.

So, how to bring my gnome desktop back?

Answer 1

I solved this problem with one line: sudo yum update. It provided me with a new gnome desktop. So the culprit is mismatch version between gnome component.

Hopes this will help anyone else.
