thanks for the heads-up, yeah that'd need to be fixed in jammy as well
(for gdm) when a hwe kernel supports simpledrm
I'm thinking if mantic 6.5 would be the first candidate

Title:
Migrate from fbdev drivers to simpledrm and DRM fbdev emulation layer
Status in gdm package in Ubuntu:
New
Status in linux package in Ubuntu:
Confirmed
Status in nvidia-graphics-drivers-470 package in Ubuntu:
Fix Released
Bug description:
The fbdev subsystem has been deprecated for a long time. We should
drop it in favour of using simpledrm with fbdev emulation layer.
This requires config changes:
DRM=y
DRM_FBDEV_EMULATION=y
FB_EFI=n
FB_VESA=n (? check this)
SYSFB_SIMPLEFB=y
fbcon will still require FB to be available, but will use the fbdev
emulation layer
At the time of filing this bug report, the NVIDIA drivers don't
support the fbdev emulation layer, so VT's would be broken on them if
this was to be enabled right now. So the drivers need fixing, and this
bug report is a placeholder until we are able to move forward.
