Do you have multiple screens? Since you seem quite technically competent, the next time it happens, can you get a backtrace of kscreenlocker_greet using gdb in a virtual terminal? Yeah using two screens. Sadly I'm not a programmer and google makes me think that's connected to C, so I'm a bit over my head here. But if you can link me some kind of tutorial or something the like i could try my luck the next time this happens. It's not too bad, thankfully. You'd go to a VT, log in, and then enter the following: gdb attach $(pidof screenlocker_greet) bt Regardless, this is a duplicate of Bug 374890. If you do end up able to produce a backtrace with debug symbols, that would be lovely, and you can paste it into a comment at Bug 374890. *** This bug has been marked as a duplicate of bug 374890 *** |
Created attachment 155844 [details] Photo of htop with the process i kill selected. SUMMARY After start from suspend I only see the mouse and a black background instead of the login screen. Just typing the password does not resolve it. STEPS TO REPRODUCE Happens regularly when i start from suspend but have not found a way to reliably reproduce it yet. Found a way to resolve it, open htop in the virtual terminal, "/usr/lib/screenlocker_greet" hugs 100% cpu (see attachment), once i killed this and switched back everything works as intended again. OBSERVED RESULT Black screen, mouse can be move EXPECTED RESULT Normal Login screen SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 5.26.5 KDE Frameworks Version: 5.102.0 Qt Version: 5.15.8 Kernel Version: 5.15.89-1-MANJARO (64-bit) Graphics Platform: X11 Processors: 24 × AMD Ryzen 9 3900X 12-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1070/PCIe/SSE2 Manufacturer: Micro-Star International Co., Ltd.
