I found a solution to my particular issue.
DISCLAIMER: I'm not positive that I experienced the same issue as other
commenters since the problem was more pronounced than others have been
describing. Since this is a new system, this was the first time I tried to
install Ubuntu. I'll try to describe what I found in some detail since this was
thread seemed like the most pertinent to my issue it may help others.
In my case I had neglected to enroll an MDK correctly. I was able to use
the system a little longer by using Ctrl-Alt-F2 to login instead of
using X. Once in the terminal I was able to see some useful messages
when the lockup occured. In one instance I got a hard lockup:
[99.065138] NMI watchdog: Watchdog detected hard LOCKUP on cpu9
The more useful message occurred during another lockup which was a
series of messages from nouveau. Here are the first and last messages:
[28.832124] nouveau :01:00.0: secboot: error during falcon reset: -110
[43.811710] nouveau :01:00.0: systemd-logind[1025]: failed to idle
channel 2 [systemd-logind[1025]]
Steps to reproduce (from memory, not verified):
- Select proprietary drivers during install with UEFI boot mode and Secure
Boot enabled.
- Enter password for MDK
- Reboot
- MDK management screen displayed, select continue to boot (THIS WAS THE
MISTAKE)
I had never used an MDK before, so did not know that you had to elect to
"Enroll" the MDK that was generated during the install process. I had
expected to be prompted for a password at some point during the reboot
based on the language in the installer. There is some user interaction
required at that menu to enroll the MDK at which point the user is
prompted for a password and then a reboot can be completed.
Description of MDK with some screenshots:

Steps to address issue once reproduced (basically remove nouveau,
install NVIDIA official driver):
I blacklisted a number of modules in /etc/modprobe.d/blacklist.conf:
blacklist amd76x_edac
blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv
I got the list of modules from: https://askubuntu.com/questions/481414
/install-nvidia-driver-instead-of-nouveau however I did not download the
driver from NVIDIA, I used one from the repository:
sudo apt install nvidia-driver-410
This laptop uses an i7-8750H which (I think) contains integrated
graphics. The 1060 should be feeding the display, but I'm not sure if
the presence of a second graphics adapter introduced a conflict.

Bug description:
First thing I notice is that the mouse cursor freezes as I'm using it,
then I hit the CAPS LOCK key and the LED indicator doesn't respond.
Then I try the "REISUB" command, but it doesn't do anything either.
Only a hard reset works, pressing down the power button for a few
seconds.
How to reproduce?
I couldn't figure out a consistent method. It is still random to me.
Version: Ubuntu 4.18.0-10.11-generic 4.18.12
System information attached.
Also happens under Arch Linux and Fedora.
I've talked to another user on IRC who seems to be having the same freezes.
