journalctl -k -b -1 --no-pager --no-hostname
On my Fedora 27 system, display often freezes unpredictably. Mouse and keyboard don't work, but system is pingable and I can login using ssh.
I actually use kernel-4.15.14-300.fc27.x86_64, xorg-x11-drv-nouveau-1.0.15-3.fc27.x86_64.
I have two monitors connected to the display adapter. Hardware is (from lspci):
01:00.0 VGA compatible controller: NVIDIA Corporation GT215 [GeForce GT 320] (rev a2)
