Hi,
After updated my system today (sudo pacman -Syyu) I noticed that my external monitor behavior has changed with my laptop.
Previously with my external monitor connected via the display port of my laptop (Thinkpad T450), when I closed the laptop screen my external monitor would automatically become the Primary Display and latop built in screen shut off. This means my login screen would automatically shift to the external monitor.
Presently ith my external monitor connected via the display port when I close the laptop screen, it appears to:
- Built in screen stay on.
- Login Credentials (GDM) stay on the laptop built in screen and do not shift to the external monitor.
To Troubleshoot:
(1) I verified I could manually make the external monitor the primary screen using the Gnome Display settings.
(2) With no external monitor attached the laptop automatically suspended when I closed the lid.
(3) I reviewed the " /etc/systemd/logind.conf" file for configuration changes:
# Use 'systemd-analyze cat-config systemd/logind.conf' to display the full config.
#
# See logind.conf(5) for details.
