Boot to secondary monitor then after login only laptop monitor works

General system Kernel, boot, graphics & hardware

So weird thing happening… When I boot my laptop with a HDMI secondary monitor it shows the logs while booting on the laptop monitor then switches to the HDMI monitor for login then switches again to the laptop monitor and no HDMI monitor at all in the settings. I go back to a snapshot and it works fine again then update and same thing happens, no HDMI monitor.

Any ideas or what can I do for logs reporting, troubleshooting etc?

Seems really strange

You can override the login screen (SDDM) default monitor, so it displays always on your laptop screen, if you’d like.

Something like this might do the trick. You’ll need to replace monitorName below with your laptop screens name. To get that, log in under an X11/Xorg session and run xrandr.

Once you have that, edit /usr/share/sddm/scripts/XSetup :

#!/bin/sh
# Xsetup - run as root before the login dialog appears

xrandr --output monitorName --primary --auto

Restart and see how it goes.

Thanks for your response! It was using both monitors for login password before but now it is external monitor login prompt then only laptop monitor after boot and the external doesn’t show in settings. I think it might have to do with the offloading GPU igpu?

So it seems that re-installing

yay -S optimus-manager

and then

sudo systemctl enable optimus-manager

sudo systemctl start optimus-manager

Seems to have worked! Looks like an error or old version?
