What new packages were installed?
Thanks for coming back to me about this. Because I can't access the
usual desktop features I'm in unfamiliar ground. The system was updated
on 3 Oct and worked. The update on 10 Oct caused the problems from
which I have been trying to recover.
xorg-xll-drv-nvidia-304xx-304.131-3 was working; 304.132-1 did not. I
believe there was a kernel update too.
I have been through several cycles of 'dnf remove' and 'dnf install',
akmods-shutdown, akmods --force. I now have a mockuser defined. But
most recently the kmod builds were failing and the logs are
I have now removed all nvidia packages in the hope of getting a working
system with nouveau. There's a long thread now on fedora-users about
that, although it has wandered off course.
Currently (KDE) plasma login with nouveau appears normal for perhaps 10
seconds, then collapses to a featureless screen with a mouse cursor that
moves but seems to do nothing else. ctrl/alt/F2 brings up the tty2
screen as mentioned below, which, without an active window, is the only
way I know to access the file system; I haven't yet tried an emergency
startx from tty2 allows login but then collapses again. Doing it from
tty3-ish says 'Could not start ksmserver. Check your installation'
which prompts unfriendly feelings but does perhaps give some clue about
what has gone wrong. But maybe it's because too many screens are being
referenced. xrandr 'Can't open display'.

I'm not clear on what you are saying here. What does "nvidia flash
screen flashes" mean?
the green nvidia logo appears briefly. I don't think it should do that
with nouveau. But there's a multi-screen factor here (VGA and HDMI
(TV)) and I saw it only on the HDMI.
And how are you using tty2? By default, Fedora
always uses tty1 during boot. Are you in multiuser, and running
to get to graphical?

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.
