On Core2Duo host p5bse I just did an otherwise successful dup to 20210604 on one of my rare installations that includes SDDM. Response to mouse and keyboard at sddm greeter is minimal, very highly delayed, if any response at all. Watching top in remote login shows SDDM using CPU varying between 25% and 89% or more. I did manage to login, but it takes considerable time to do. Switching themes didn't help. Am I alone in this? Attachment is grep of sddm from journalctl -b. Trying to switch back and forth between autologin or not, as when trying to disable autologin to enable a troubleshooting a broken X[1], is proving very difficult. It seems once autologin has been enabled, SDDM remembers even after editing /etc/sddm.conf.d/ to remove the autologin username from the User= line, and restarting xdm with systemctl more than once. I gave up and rebooted to try to get back to no autologin mode. The result of that initially was a black screen instead of a greeter, and sddm not showing in top. I got the greeter back, but it's still unresponsive and using excessive CPU.
