New Machine, New Fedora 25 Install - High CPU Usage

If you remove gnome and wayland, you should have no GUI. The problem is probably a wayland bug.

rtmistler is providing good advice. A couple of "my 2 cents"

Can't one turn off the GUI by

Code:

init 3

to reboot in Multi-user mode without GUI? [I'm a CentOS guy, haven' done Fedora for awhile.]

Have you looked into Webmin? It's a web-based GUI I use for those things I'm not comfortable or knowledgeable enough to do from the CLI on a server without a GUI.

Editing the kernel line in grub.cfg at boot will let you boot into the CLI. Just add the word "text" (or the number "3") without quotes to the end of the line that start ""linux" or "linux16"

Actual kernel line from my Fedora 26 installation:

Code:

linux16 /boot/vmlinuz-4.11.8-300.fc26.x86_64 root=UUID=d0883b52-4b3e-40b9-b997-e1806c11ae1d ro LANG=en_US.UTF-8

Edited version:

Code:

linux16 /boot/vmlinuz-4.11.8-300.fc26.x86_64 root=UUID=d0883b52-4b3e-40b9-b997-e1806c11ae1d ro LANG=en_US.UTF-8 text

then continue the boot process

I wonder if that's still supported with systemd. I'm in another active thread where a server with GUI has bumped into video driver issues with wayland. Try changing the line as suggested in /etc/gdm/custom.conf and reboot to re-enable xserver.
