Title:
Laptop suspends on login with external screen and lid closed
Status in gdm3 package in Ubuntu:
Incomplete
Bug description:
Release: 18.10
with latest updates installed.
I have mouse, keyboard and external screen connected to the laptop, lid is
closed.
Right after boot I'm selecting user, typing password, pressing enter and
after a few seconds laptop suspends (fan stopped, keyboard lights turned off).
Pressing space on a keyboard wakes it up.
MSI GL72 7RD, nvidia drivers installed 390.87, X11 ubuntu desktop
session selected in login screen.
Could be resolved if sleep is disabled on systemd side:
sudo systemctl mask sleep.target suspend.target hibernate.target
hybrid-sleep.target
