SDDM "login failed" after migrating to new hard drive (Debian Testing + KDE)
by andigena from LinuxQuestions.org on (#586FR)
My laptop came with a 1TB hard drive, but I recently switched to a 512GB SSD to improve speed. To do that, I dd'd the EFI partition and cp'd the root and home partitions. I think I messed that up at some point with permissions because after doing so, I had to go through and fix permissions for a few of my programs to work, but I managed to figure out the problem for most of those. I'm still having issues with SDDM, though. It'll allow me to log in right after booting, but if I try to log in after the computer has gone to sleep, it will give me the "login failed" message (even with the correct password and user). I have to reboot my laptop if it has gone to sleep so that I can log in normally. I tried reinstalling SDDM, libpam0g, and packages to do with kwallet, but that has not helped. Any ideas for what might be going wrong or what I could do to figure that out?
