SUMMARY Screen remains black after waking from sleep on lock screen (SDDM) without prior login. Meaning, I'd reboot the system, let it get to the lock screen, then put it to sleep from the "sleep" option there. Come back later, wake it to log in and it is a black screen STEPS TO REPRODUCE 1. Reboot the system and wait for the lock screen (SDDM) to appear. 2. Without logging in, put the system to sleep. 3. Wake the system from sleep to log in. OBSERVED RESULT Upon waking, the screen remains black with no option to interact or proceed to the login screen. I'm then forced to go into a tty to reboot the system. Tried to run sddm from the terminal, it shows up, but it never logs in after I enter my password. It stays on the plasma login logo forever. I HAVE to reboot EXPECTED RESULT The system should display the lock screen as normal, allowing the user to log in after waking from sleep.

Quick correction: SDDM is the *login* screen, not the lock screen. The lock screen is the thing that locks the screen after you're already logged in. Can you confirm that you're talking exclusively about the SDDM login screen here?

Sorry about that. I always call it lock screen, but yes I am talking about SDDM specifically. It only happens on SDDM.
Thanks. I cannot reproduce the issue on my Fedora 41 system with SDDM 0.21. I suspect it's actually an SDDM issue. Can you report it at https://github.com/sddm/sddm/issues? Thanks!
