SUMMARY Put system to sleep/suspend normally from the Application Launcher, wake it up, click on the "suspend" button in sddm then wake it up again to log in, causes a permanent black screen. Not sure if this makes sense, but it happens on every single distro I have ever run, so that tells me it is either a plasma issue or an sddm one. Not sure. At that point, not even tty would should up. Nothing, just permanent black screen. I would then half to force the pc off by holding down the power button. This worries me that I may just corrupt my ssd one day. STEPS TO REPRODUCE 1. Put system to sleep/suspend normally from the Application Launcher 2. wake it up 3. click on the "suspend" button in sddm 4. wake it up again to log in OBSERVED RESULT Permanent black screen EXPECTED RESULT To log in normal SOFTWARE/OS VERSIONS Operating System: Nobara Linux 41 KDE Plasma Version: 6.3.3 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.2 Kernel Version: 6.13.7-200.nobara.fc41.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 5700G with Radeon Graphics Memory: 31.2 GiB of RAM Graphics Processor: AMD Radeon RX 6600 Manufacturer: Gigabyte Technology Co., Ltd.

Cannot reproduce on git master. Do you have multiple monitors? If so, this may be Bug 494262.

The bug you have linked mentions that they lose one monitor and are able to use the second one. I lose both, and I can't even log in anymore. The only way I can get back into my system is by holding down the power button to force it off.
Does the black screen have a cursor you can use? On the black screen, if you type Alt+Space, does KRunner come up?

I don't have any cursor or any activity at all. Just plain black screens. I can't even get into a tty. Only solution is holding the power button down to shut it off.
Thanks. That sounds quite bad.
(In reply to Nate Graham from comment #5) > Thanks. That sounds quite bad. It is bad, if I forget to log in then suspend the system from the desktop instead of SDDM, which I've learned not to forget :)
