Your XorgLog seems to show some bugs with the Nouveau driver that may make the screen appear to freeze:
[ 11270.264] (WW) NOUVEAU(0): nouveau_
[ 12931.381] (WW) NOUVEAU(0): nouveau_
[ 13043.502] (WW) NOUVEAU(0): nouveau_
Can you please try installing the official Nvidia driver:
sudo apt install nvidia-driver-390
and tell us if that avoids the problem?
