I am running Kubuntu 18.04 on a Dell Precision 5810 with a NVIDIA Quadro
K4200 graphics card. The driver is NVIDIA 390.77. I have two Dell 27"
U2713 monitors with display port cables.

If the screen is locked for a long time, i.e. when I leave work for the
day, but not during lunch, the keyboard no longer responds. The mouse
cursor is still moving but does not seem to interact with the screen.
If I use ssh to kill the session with loginctl, everything starts
working again.

I will try unplugging the second monitor tonight to see if that makes a
difference with the issue.

I was offsite all day yesterday. I came in today and the lock screen
was responsive. Unplugging the monitor seemed to prevent the issue.
