I also installed Mesa-dri-vc4, played with loading vc4 kernel module, adding dtoverlay=vc4-kms-v3d-pi4, removing "nomodeset" kernel option (https://bugzilla.opensuse.org/show_bug.cgi?id=1172924), but I couldn't get a working, hardware accelerated Xorg.Does it display something, but not accelerated, or does it display nothing?
By default (the old and working configuration) it's not accelerated (glxinfo says it uses llvmpipe). When I tried changing it to use vc4 I got black screen. Not even text console would show up.
Also I'm not sure if I've done everything correctly. There's a lot of information and guides on the Internet, but a lot of it is outdated, there are some ambiguities (like should I use vc4-kms-v3d, vc4-kms-v3d-pi4 or vc4-fkms-v3d), and some apply only to other distros.
Btw (I don't know if it's relevant): I'm using 7" touchscreen, which is connected by ribbon cable to DSI port, not HDMI.
Is there anything still missing? Or does it require some more special configuration?I think you also need Mesa-gallium.
I already have it and I see nothing relevant in this package.
