Hi!
Can you provide more information about your system? Which architecture
are you using, and what graphics hardware do you have?
What are the errors you are seeing with drm-legacy-kmod? That should be
a drop in replacement for what's in base, it is the exact same code, the
only difference is changes to make it load firmware from
gpu-firmware-kmod instead of the firmware blobs in base.
When building your own kernel, as is always the case on CURRENT, you
need to build the drm kmods from ports, rather than use the preexisting
packages. It is OK to build these from ports while still using packages
for the rest of your system.
Regards
