I recently did a fresh install of Fedora 26 Workstation. I use gnome over X11 because I do image processing and need xrandr. All went well and all worked without error for about a month.

Then the following error was displayed on the screen (this is from journalctl) and graphical login failed.

Oct 17 04:32:04 localhost.localdomain kernel: nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 3c7e3c [ IBUS ]
Oct 17 04:32:04 localhost.localdomain kernel: nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 10ac08 [ IBUS ]

Looking around various forums over the past year or so I see that some combination of nomodeset,
nouveau.modeset=0, NVIDIA.modeset=0 and intel.modeset=1 are recommended as additions to kernel
parameters. I've tried every combination. No joy.

What does work is first logging in via ssh. Then I can successfully login to the console as I usually do. This
is also from journalctl.

Dmesg didn't seem to have any useful additional information. Any pointers on where to look next would be greatly appreciated.

Maybe install nvidia drivers?

Maybe install nvidia drivers?

I will get to that, but I want the nouveau drivers working first.
