DisplayPort Monitor at boot (encryption screen)

[jfkp]

As I understood, xorg / xrandr or lightMD manage which monitors is primary only from the logging screen?

What can I set in order to get the initial "encryption screen" on my DisplayPort monitor and not on my laptop monitor? Grub? I found nothing in my BIOS (Dell A13).

Thanks.

n.b. When I go to BIOS and then reboot, sometimes the encryption screen displays on my DP monitor.

EDIT: when I press F8 (switching screen) my DP monitor is reacting but won't display the logo and password field... Quite strange.

Basically you should make a Startup Application file, which determines the primary monitor. To know your monitors, run

Code: Select all

xrandr

Thanks.

It doesn't work. Here is my script:

Code: Select all

[Desktop Entry]
Type=Application
Name=DP1
Comment=Set the default monitor
Exec= xrandr --output DP1 --primary

What I find really strange is that DP1 reacts but doesn't show the logo and password field.
