--- Comment #1 from Roberto Guerrini (robyguerrini@yahoo.it) --- Tested with 5.8 rc3 also and the result is the same .... black screen ... but the computer works so I think it is the Nouveau driver with the gtx 760 to wrong the video output.

--- Comment #3 from Ilia Mirkin (imirkin@alum.mit.edu) --- Has nouveau ever worked with this board? Can you get dmesg from a failing boot?
Unfortunately without logs, it's a bit hard to tell what's going on. Chances are the machine is fine, so you should be able to ssh in and get them. Or perhaps you can acquire logs from a previous boot, depending on your logging system.

Hi, you are right ... you need the log to know what happens ... As soon as I can I reassemble the 5.8 kernel and then I will save the log to make you understand what the problem is !!! However with Kernel 5.7 it works perfectly .... this with the Nouveau driver ... there was the problem with the 5.7 of the hadmi audio not working but it was solved with the 5.7.7 version which works very well but unfortunately the 5.8 it doesn't work and the screen remains black even if the machine is free ... so something of the video driver has been changed from 5.7 to 5.8 and with the Nvidia gtx 760 and driver nouveau the result is this ... soon I'll send you the log 5.8 not working ... hello and thank you !!

--- Comment #9 from Nathan Bryant (nbryant@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
