It affects to: Kubuntu 18.04, Dell Latitude 7490. I could start by blacklisting the intel-lpss-pci module (in this case the mouse doesn't work) and loading it again after boot (the mouse works again fine).

The mouse pointer is frozen, the keyboard does not even respond to CAPS LOCK or NUM LOCK, pressing CTRL+ALT+F2 shows no reaction. I cannot work with my machine at this point and have to hard reset it. Selecting advanced boot options in grub and selecting the previous linux kernel 4.15.0-176 makes it work again. So this bad bug was introduced with the 4.15.0-177 kernel release. I tried removing the nvidia-driver-510 package, presumably making Ubuntu use the "nouveau" driver, and with that, I could use the welcome screen and log in, but the machine still froze shortly afterwards. So maybe this is some sort of interference with my GeForce 1080 graphics card, but it is not specific to the driver used.
