Install a VNC Server.

sudo dnf -y install tigervnc-server 

Add a rule to firewalld.

sudo firewall-cmd --add-service=vnc-server
sudo firewall-cmd --runtime-to-permanent 

As the user you’re configuring a VNC session for, set a VNC password.

vncpasswd

Add a VNC configuration file to ~/.vnc/config.

session=gnome
securitytypes=vncauth,tlsvnc
geometry=1920x1080

Then edit the main VNC server configuration file /etc/tigervnc/vncserver.users.

sudo vim /etc/tigervnc/vncserver.users 

Add your user and assign to the first display.

:1=fedora

Now start the server.

sudo systemctl enable --now vncserver@:1

You can now access the server on port 5901 in your VNC client of choice.
