I was looking at this today and was getting errors about the kernel not being supported.
Cannot detect kernel bootsplash support Is it a custom kernel?
After some internet searching I found a how-to on here that noted that from kernel 6.4 onwards bootsplash was broken: Bootsplash patches for linux64
I’m on 6.5 now and still seeing the same. Is anyone aware of where we can track this issue or if there are plans to fix it?
NOTE: I know this is bumping an old thread but this seems to be the best place for a reply with a link to sit if someone searches for it later.
