    Sorry, I completely forgot this feature isn't yet [1] enabled by
    default.
    This is what I get on my system:
    $ journalctl --list-boots | tail -n3

    You can read a brief tutorial on journal here. [2]
    For now, until you enable persistent journal, you have only current
    boot journal:
    $ journalctl -b 0

    It looks like "nouveau" deadlock bug. [3] Have you tried to install
    proprietary driver?
    Last supported driver version for your VGA is 390, so you will need
    to install "nvidia-legacy-390xx-driver" package from Debian non-free
    repo.
    
          $ sudo apt install nvidia-legacy-390xx-driver
      nvidia-legacy-390xx-kernel-dkms nvidia-legacy-390xx-kernel-support
