vdflux; Most likely:
and I am able to log in properly. Am I good to go?
No issues now with booting ?
a check/confirmation:
sudo lshw -C display
shows nvidia as the driver in the configuration line:

cat /var/log/gpu-manager.log
Indicated no errors -

cat /var/log/Xorg.0.log
## or maybe here - depending on the desktop/release:
cat .local/share/xorg/Xorg.0.log
No screaming and hollering ib the log files ->
