Hi. I’m experiencing the same problem described here. Basically when the laptop wakes from sleep there’s a blank screen with the cursor, I can move it and can press Ctrl-Alt-F2 to go to TTY2 and reboot. However, the solution in that thread isn’t applicable to my situation as I don’t have an nvidia card. It started happening today after a general update with pacman -Syu. Last time I updated before was 30 Oct.
The problem was still there with kernel version 6.0.9. It’s difficult to tell if the problem has gone away for good because it’s intermittent, it doesn’t happen every time. Now I updated the linux kernel to 6.0.12. Let’s see if that helps, though I’m under the impression that the problem isn’t just related to the kernel but also to KDE or SDDM.
I’m looking at the journalctl output from last boot, where the problem did occur, and don’t see anything unsual after opening the lid (ie waking from sleep) and before rebooting from tty2.
$ journalctl --no-hostname --pager-end -b -1
