Comment # 38 on bug 1217613 from Fritz Hudnut

[CODE] just delete or move /etc/modprobe.d/nvidia-default.conf and reboot.

    Also rebuild initrd dracut -f --regenerate-all [CODE]

The problem is the "intermittency" of either the console or the operator . . . 
today running 
[CODE] # zypper rm /etc/modprobe.d/nvidia-default.conf [/CODE]  did remove the
.conf file . . . or this time did I run simply w/o the "zypper," 

[CODE] # rm /etc/modprobe.d/nvidia-default.conf [/CODE] and that did remove the
file, but did not restore "nouveau" into lsmod . . . .  I had run the dracut,
also not restoring nouveau to lsmod.

I then tried to run "modprobe nouveau" and that **instantly** froze the mouse
and GUI . . . after a few seconds I shut it down with the power button.

On cold boot, that does seem to have restored "nouveau" back into lsmod and the
 “revival from suspend” function in my machine. 

I’ll have to monitor it for longevity.
