--- Comment #9 from Nathan Bryant (nbry...@optonline.net) ---
I'm seeing similar symptoms on my Geforce GTX 1070 (GP104). Screen blanks after
GDM login, Wayland works, Xorg doesn't. This is a regression from 5.7 to
5.8-rc1.
As long as I only have my primary monitor connected, after the failure I can
still switch to another VT with Ctrl-Alt-F3 and log in to the text console.
~/.local/share/xorg/Xorg.0.log has a few of these:
[ 17.240] (EE) modeset(0): failed to set mode: Invalid argument

drm/nouveau/kms: Support NVIDIA format modifiers
Allow setting the block layout of a nouveau FB
object using DRM format modifiers. When
specified, the format modifier block layout and
kind overrides the GEM buffer's implicit layout
and kind. The specified format modifier is
validated against the list of modifiers supported
by the target display hardware.
v2: Used Tesla family instead of NV50 chipset compare
v4: Do not cache kind, tile_mode in nouveau_framebuffer
v5: Resolved against nouveau_framebuffer cleanup
