Dual-graphics: Module fbcon not found
System: ASUS Z390-PRO with i5-9600K and Debian 4.19.67-2+deb10u2 and i915 Intel graphics
I am trying to install a second graphics adapter (MSI Radeon HD 5450). Relevant output from lspci:
00:02.0 VGA compatible controller: Intel Corporation Device 3e98
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series]
The system is a clean install that is working fine without the second adapter. I think I have come a long way with the configuration but something is still missing after two days of work. I get the following error in my /var/log/lightdm/x-0.log:
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
modprobe: FATAL: Module fbcon not found in directory /lib/modules/4.19.0-6-amd64
intel: waited 2020 ms for i915.ko driver to load
(II) [KMS] Kernel modesetting enabled.
I can not access the tty[1-6] nor is there anything on the graphics output post the GRUB menu when the second card is booted up. Interestingly, when I xrdp into the box, I can start my Xcfe4 desktop just fine!
I am using the following xorg.conf file, which should be OK for the system:
Section "ServerLayout"

The Xorg.0.log file does not look too bad:

I feel I am close but how can I proceed from here??? Any suggestions are welcome.
Update:
I think there is a problem with the Intel UHD Graphics 630 driver. In lspci it should say:
Kernel driver in use: i915
Kernel modules: i915
But that part is missing. Also, when I unplug the second graphics card, remove the xorg.conf and reboot, the tty terminals and the display manager are working fine but there are still errors in the Xorg.0.log:
