GNOME ui / gnome-shell broken

[fnatter]

hello fellow CentOS7 users,

I have the problem that if one user (we have central homes) logs into any machine,
we only see a desktop with icons, but no window decorations or top/bottom bars ("panels")
(for both gnome-classic and gnome3).

I can fix the window decorations by running "metacity --replace",
but the other problem remains.

I have an up-to-data Scientific Linux 7 (_very_ similar to CentOS7).

I tried to remove .gnome, .gnome2, .gconf, .metacity, .cache, .dbus, .dmrc.

I noticed that when starting "gnome-shell --replace" from a terminal,
I get "Failed to migrate monitor configuration for ... Empty Configuration",
and when running gnome-control-center, the options "Displays" shows
"Could not get screen information".

~/.config/monitors.xml exists. xrandr shows:

How can I fix this? Do I need to reset more of GNOME's config?

Many Thanks and Best Regards!

This happens both when logging in physically and when logging in virtually
using VNC.

[fnatter]

When running gnome-control-center, I get:
Name "org.gnome.Mutter.DisplayConfig" does not exist

[TrevorH]

Is mutter installed and up to date?

Is mutter installed and up to date?

On other machines we did not need it. I have installed mutter now which did not make a difference.

Thanks!
