This feels little but I am again at a loss

I just installed 24.04 onto a Dell 7490 which went well I got a Dell WD19DCS USB-C docking station and two external monitors

all kinda works except one thing

lid closed on the laptop I don't see the bios boot, or the prompt for the disk encryption, or the user/pass screen they are all on the built-in laptop screen I have to open the lid to the laptop and interact with the laptop directly then.. I went into the displays and disabled the built-in screen which moves the primary to one of the external monitors which is fine but none of this happens until after the boot process completes..

Oh and for the folks that want to know I am cheap and buy mostly used refurbished laptops online so that's why i have an old/new 7490 even got it 24.04 to install on UEFI and enabled secure boot too.. but the boot thing is annoying..

12Aug2024 ok progress I read these URLs https://ubuntuforums.org/showthread.php?t=2473462 Force gdm login screen to the primary monitor Force gdm login screen to the primary monitor

and sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/monitors.xml sudo chown gdm:gdm /var/lib/gdm3/.config/monitors.xml

and now after I unlock the hd encryption, which is still on the laptop screen, I do get my gnome login/pass on the external monitors..

anyone know how to get the HD encryption prompt to show on the external monitors, or even on all monitors. I am not even seeing the external monitors have a signal until the HD is opened and OS boots..

I mean I can keep doing this work around, waiting a suitable amount of time,
then blindly type in the HD password, and hope I then get passed along to the GDM login

But it just feels cludgy, ya know?

13Aug2024 and i can interrupt the boot process to look at the bios hit Fn F8 and switch the bios screen to the external monitor exit the bios and the freaking bootsplash is now on the external monitor but it doesnt keep doing that after I power off and reboot.. its like it knows 'how' to do it right but just won't for some reason..

it feels like I am talking to myself some days.. :-)

I found a solution in the bug tracker related to this new ubuntu 24.04 behavior (note that I'm an AMD user and you might have to adapt for nvidia or intel) :

You should be able to work around it by adding 'amdgpu' to '/etc/initramfs-tools/modules' and then run:

sudo update-initramfs -k all -u

or get the system to automatically insert all the modules you're currently >using by changing the MODULES line in '/etc/initramfs-tools/initramfs.conf' >to MODULES=dep and again:

sudo update-initramfs -k all -u

(Source: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/2069039)

By my understanding, the drivers related to external display have been moved out from early boot sequence to gain in performance.
