just to make sure, what does it actually look like when you enter a different password for this grub2 disk encryption that is activated during first clean install from the opensuse 15.4 installer/setup? i see no difference when entering a wrong password deliberately? there is initially. this machine boots as follows: - power on - hp logo on screen visible - Weltome to GRUB! .... printed to the left upper corner attempting to decrypt master key.... enter passphrase for hd0.gpt2 (.... some hash(?) value seen here....) : I then need to enter my password that I set during the initial leap 15.4 install. until yesterday: when having entered the correct password there, the screen eventually got cleard, hp logo vanished and then a normal grub menu was being presented with three entries, first like to boot normal 15.4 kernel or so... two additional lines I dont even remember any more, like in the old days... opensuse safe settings or rescue or similar. So since yesterday, when I enter my password (or anything here at the fist prompt).... after a little while there is briefly something being printed to the sceeen (at the top?) but vanishes so quickly to land into tha grub very basic terminal prompt or so.... I fail to see any differences in behavior when using a false password or when using my supposedly correct password typing it very carefully. Any way to see any logs of whats happening in this basic grub stage? of seeing that briefly presented message after the password? to see any differences? so see whats going on? What can I do now? where to request for support or help? thanks.
