@Martin: I don't know if my, now numerous, issues with TW and Leap relate to this problem. It's just that a huge ration of problems have seemed to beset my various openSUSE installs, all in overlapping succession . . . that it is becoming problematic to regular use of those systems. I just spent several weeks trying to get TW to simply "log in" in a reasonable time . . . finally via this list-serve finding out that "sddm-qt6" needed to be installed. Concurrent with that grub handling went awry in TW, so I moved it to Leap . . . and the problem followed over there. And, now Leap 15.6 won't revive from suspend . . . what is supposed to be "rock solid" and "tested" is now . . . coming up lame. Sounds like my personal problems with Leap are not related to this thread, but possibly the problems with again TW booting to ER mode might be??
