I was playing around with the System Settings, and I foolishly increased the Zoom to 10.0 (normal being 1.0), after which the system crashed with an error saying:

A problem has occurred and the system can't recover. Please log out and try again.

How can I use the terminal to change the zoom settings back to normal?

The configuration settings can be changed using dconf. The following command would reset the magnifier settings:

dconf reset -f /org/gnome/desktop/a11y/magnifier/

This put all the magnifier settings back to default, and the magnification factor was back to 2.0.

In general, all the dconf settings can be found by running dconf dump /.

I use this steps for fix that error on CentOs 7: Open terminal: Ctrl+Alt+F2 (or F3)

sudo yum history package-list gjs
sudo yum history package-list gnome-shell
sudo yum update --skip-broken

After a long wait for the installation to complete , Update complete , Clean up complete. And then restart.

sudo shutdown -r now

Then i was able to log in.
