Any cards in particular?

– whilst I didn't mention Radeon there, for me it _was_ the Radeon story
that seemed to improve a few months ago.
<https://bsd-hardware.info/?id=pci:1002-6841-103c-17a9> AMD Thames
[Radeon HD 7550M/7570M/7650M]
For example old RS880 [Radeon HD 4200]. After deprecation of
graphics/drm-fbsd12.0-kmod I found that it is still supported fine on
12-STABLE with legacy /boot/kernel/radeonkms.ko from the base. While
trying the driver from graphics/drm-fbsd12.0-kmod I was not able to use
this card with gdm, only startx or x11/slim worked. On 13-ALPHA this
card still works fine with deprecated graphics/drm-legacy-kmod.
