Just curious.....i read you all saying you don't run dnf "inside a desktop" am I to assume that me running a terminal AFTER LOGGING IN TO THE DESKTOP is not a good idea..? I'm sorry.... It's just that I'm "old school" and only know about running commands from within a terminal.....but it's always been AFTER I've logged into the desktop...
You are running a terminal under X, so you are susceptible to the problem if you have hybrid graphics. You could try the systemctl command Adam mentioned to confirm, knowing that it will crash X if you meet the criteria, and lose anything in progress.
What Adam is saying is you need to run dnf in a virtual console environment (Ctl-Alt-[F2-F6]) to avoid the problem. This is non-X, and so even if X crashes, the dnf update won't be affected.
There is nothing wrong with running a terminal under X for other purposes, just with running dnf update, and even then only for people that meet the criteria.
