Hi all. I was having an issue in which my Fedora 25 installation wouldn't scale the login screen, activities bar, or other GNOME features, despite already setting the scaling factor to 2 in GNOME tweak tool. I found a solution regarding the login screen on another forum, but it actually fixed the scaling of my system menus and activities bar as well. I am posting it here, so it is added to the knowledge base and people can find it in the future. Here was the quoted solution:

I finally figured this out w/ the help of the following link:

I modified the file:

changing the default value to 2.
<key name="scaling-factor" type="u">

and then running
glib-compile-schemas /usr/share/glib-2.0/schemas

all commands executed with root privileges.

2017-01-26 15:44:20 -0500 asked a question Fedora 25: Cannot re-login after logout

Hi all. I am experiencing a problem regarding logging into my graphical session with Fedora 25 (4.9.5-200.fc25.x86_64).

If I log out of my account, and then I try to log into any account, the screen goes black for a moment, and dumps me back at the login screen.

I switched to tty2 and checked for errors in journalctl. This is repeated many times:

fedora gnome-session-binary: GLib-GObject-CRITICAL: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

Followed by:

Unrecoverable failure in required component org.gnome.Shell.desktop

I can start a new GNOME session in tty2 by running startx. However, I can't ever log in again from tty1 until I reboot.

My system is fully updated via "dnf update" as of yesterday.

Extra info: I am using an Nvidia GTX1060, with Nvidia driver:
