I don’t see graphic background (disk password screen) when I try to boot with any kernels above 5.12+
It feel like something with graphic initialization somewhere around grub. Anything changed?
Because of this I can not boot with this fresh kernels. Today, tried with kernel-latest and it fill the same. I don’t see graphic and system can not boot and stop at the step of plymough-wait…
Did you mean kernel 6.12+ and not 5.12+?
Maybe it’s a hardware-specific issue that is not related to Qubes OS. Try to boot Fedora Live with the same kernel version that is not working in Qubes OS.
