How to upgrade from Fedora23 to Fedora24 with less stress.

Let's do "By the book" instructions:

Update software and back up your system.
dnf upgrade --refresh

Install the DNF plugin.
dnf install dnf-plugin-system-upgrade

Start the update with DNF.
dnf system-upgrade download --releasever=25

Reboot and upgrade.
dnf system-upgrade reboot

Now let's fix the problems.
Window themes has vanished? The title bar on all windows is twice the size anyone wants and not colored.
Here's the fix:
First, Disable Wayland and Skip login, nobody else uses this computer!
Your /etc/gdm/custom.conf file should look like this:
# GDM configuration storage

# Uncoment the line below to force the login screen to use Xorg





# Uncomment the line below to turn on debugging

Create or edit a file called ~/.config/gtk-3.0/gtk.css
@define-color theme_bg_color #3366cc; /* #3366cc; for blue */ /*cc6600; for red *//* #669900; for green */

.header-bar.default-decoration {
padding-top: 0px;
padding-bottom: 0px;

.header-bar.default-decoration .button.titlebutton {
padding-top: 0px;
padding-bottom: 0px;

/* Get rid of unsightly line in ssd title bar and reduce button padding */
.ssd .titlebar {
border: none;
background-image: linear-gradient(to bottom,
shade(@theme_bg_color, 1.042),
shade(@theme_bg_color, 0.999));
box-shadow: none;
border-top: 1px solid shade(@theme_bg_color, 1.072);

.ssd .titlebar:backdrop {
background-image: linear-gradient(to bottom, @theme_bg_color);

.ssd .titlebar .button.titlebutton {
padding: 3px;

As usual to:
