Bug Description
Step:
1. There are two users, A and B. A is adminstrator, B is standard user, B is automatic login.
2. Boot into Ubuntu 18.04.1 LTS, it will automatically login to user B.
3. Switch User to user A without logging out.
4. Switch User back to user B, either by logging out from user A or not.
Expected: it will be back to user B normally.
Actual: it backs to user B but become not responding to keyboard, touchpad, or mouse input. Closing the lid is responded normally, which is locking the screen, the three-arrows in the lock screen is animated normally, clock is updated.

If you're using a Xorg session (the default one named "Ubuntu") then the mouse pointer is moved by xorg-server independently of gnome-shell. This means that if the mouse pointer is frozen then it's either Xorg or the kernel that's freezing.
If you're using Wayland and not using a Xorg session then please try using the latter.
Can you please reproduce the problem again, recover using the lid trick and then without rebooting run:
dmesg > dmesg.txt
journalctl > cur_boot.txt
If you need to reboot to recover then instead please run this immediately after rebooting:
journalctl -b-1 > prev_boot.txt
and send us the resulting text file(s).
