Attempting to uninstalled PulseAudio
This is a long post because I included all the events leading up to the failure.
Yesterday I installed PulseAudio equalizer by following the instructions on https://www.fosslinux.com/1584/how-to... It sounded great.
Then I installed impending updates and rebooted.
The speaker and headphones where never heard again. There is no sound.
And the system menu space for selecting headphone or speaker, now says "Extension initializing..."
In Settings > Sound, "Output volume" slider and "Input volume" slider are grayed out and stuck on zero.
I tried installing pavucontrol as suggested by xmetax on https://ask.fedoraproject.org/en/ques... And rebooted to initialize. Unfortunately installing pavucontrol did not bring back the sound. System menu and Setting > Sound are still the same.
So I uninstalled PulseAudio:
$ sudo dnf remove pulseaudio
$ sudo dnf clean all
The "dnf clean all" hangs for 20 minutes. So I ctrl+c. But the keyboard is unresponsive. So I hard boot. Usually a login GUI appears after booting, but not anymore. Now only a terminal is displayed:
Fedora 25 (Workstation Edition)
Kernal 4.9.13-201.fc25.x86.64 on a x86_64(tty1)
localhost login: wolfv
Password: ******
[wolfv@localhost ~] $ ls
All my files and data are still there (and I made a backup before installing PulseAudio, so the data is safe).
Is there a way to get the Fedora GUI login and Gnome desktop running again? I can do a clean install if all else fails. But this was a clean install 5 weeks ago, which I do not want to repeat. Do you have an idea on how to get the GUI login and Gnome desktop back?
Thank you.

Why did dnf rollback attempt to remove Updates, Opera, chrome? They were not listed by dnf history.
According to this link, https://docs.fedoraproject.org/en-US/...AdministratorsGuide/sec-DNF-Transaction_History.html dnf remove command removes the specified packages from the system along with any packages depending on the packages being removed.
When I removed pulseaudio it remove all its dependencies which included gdm and gnome it self. So now I am hesitant to use dnf remove.
I tried:
$ dnf history undo 14
$ dnf history undo 13
$ dnf history undo 12
And rebooted. The undo did not fix the following things.
The computer's sound is silent. The system menu space for selecting headphone or speaker ...

How about rephrasing your the title of your question? As you figured out,
dnf remove pulseaudio
removed gdm and gnome-shell, not thednf clean all
.@florian, Good idea. Changed title to, "Attempting to uninstalled PulseAudio."
