Re: nvidia 304 and fc23: black screens after updating today
No expert, and I don't run nvidia anymore, but I'll try to help.

fc23 upgrade. That was reported here and solved on 30 June. Since
then it has been working well, but after installing the new packages
today I get black screens with kernels 4.7.3, 4.7.5 and 4.7.6
What new packages were installed?
'dnf downgrade xorg-x11-drv-nvidia-304xx --allowerasing'
apparently
completed but then akmods-shutdown errored. After re-upgrading,
akmods-shutdown completed, and the nvidia flash screen flashes, but
then all goes black again, for all installed kernels. I'm using tty2.
I'm not clear on what you are saying here. What does "nvidia flash
screen flashes" mean? And how are you using tty2? By default, Fedora
always uses tty1 during boot. Are you in multiuser, and running startx
to get to graphical?
Xorg.0.log looks ok apart from 'ACPI: failed to connect to the
ACPI
event daemon' and suggests looking at the ConnectToAcpid and
AcpidSocketPath options, which I have not yet done. I don't know if
this is likely to be the real problem.
Unlikely. ACPI is the power management daemon. It shouldn't prevent
the driver from working properly to access the monitors. You could
disable any screen savers you have enabled to be sure; if they are
taking effect immediately it might cause blank screens, even though the
driver is working.
