I installed Mesa 22.3.3 on openSUSE 15.4 on a laptop (Intel CPU and GPU) and
when I rebooted, I got a black screen and could not operate it at all.
I think this is the reason why it was marked as WONTFIX.

However, if a file with the contents of blacklist nvidia is placed in
/etc/modprobe.d, X starts without any problems.
However, when I execute $ vdpauinfo here, the following strange error message
appears.

������������������cannot find libvdpau_nvidia.so is not found 


In other words, Mesa does not cause problems on nvidia, amd gpu pc's, but on
Intel GPU pc's it also pulls in nvidia modules etc., causing strange behaviour.
