Hi Michel,

Thank you for looking into this, and for assigning the bug.

In the meantime, I have found a workaround or a solution.

The system needs to be booted with systemd-boot bootloader
(or perhaps any other supporting UEFI boot)

When I boot Ubuntu with standard, installed during installation
grub2, radeon driver would't detect external displays connected via
Display Ports.

But when I boot system using systemd-boot installed by Arch Linux (or KaOS),
it detects displays normally, and works correctly, supporting
all external displays as expected.

I think this is related to some aspects of the hardware not
exposed in BIOS boot mode, and exposed in EFI/UEFI boot mode.

Preferred solution would be working radeon driver in BIOS mode
if possible, or, if that is not possible, some meaningful message=20
in the system journal explaining that certain features=20
(e.g. external monitors via Display Port) will not be supported=20
unless the system is booted in EFI/UEFI mode.

Thank you,
Heigh

The problem is Macs expose the vbios for some cards in a propr=
ietary way.=20
IIRC, the vbios is only available via EFI prior to the OS loading.  The
bootloader needs to snag the vbios and then make it available to the OS whe=
n it
loads.  I'm not really a Mac expert so I don't remember all the details.=20
There's no way to work around it in the driver.
