I have a Dell XPS 9570 laptop on which I've installed SDDM and KDE. Since mid-July, sometimes when I wake up my laptop after suspending it, it shows a mouse cursor on an otherwise black screen. I can only recover by switching to another virtual console and typing sudo systemctl restart sddm.
I believe this problem started when I upgraded from linux-5.7.7 to linux-5.7.10; I can give version numbers of other packages if relevant.
Here are the dmesg logs (from journalctl -o short-precise -k -b -1) starting from when I woke up the computer; I promptly rebooted the computer from a virtual console, so I've included the logs all the way to EOF:
