I am a Tumbleweed user. Packman ML informed me that Mesa 22.x or later is WonfFIX (https://bugzilla.opensuse.org/show_bug.cgi?id=1207425) with Leap 15.x, so I installed Leap 15.4 on my laptop & built Mesa, Mea-drivers on my laptop and checked it out. I then informed you that this might be the cause of WONTFIX. First of all, it's not very likely that it won't boot unless nvidia is blacklisted! Or do you just leave WONTFIX alone? If so, please let me know. I'll report it to ML.
