Version-Release number of selected component (if applicable): Fedora 24 Kscreenlocker 5.7.4 How reproducible: 100% Steps to Reproduce: Each time Kscreenlocker takes control of the screen! Actual results: Only a totality black screen. Does not react on any key or mouse movement. Expected results: At least: Show the password line for unlock at mouse movement or key hit. May also displays screensavers like in KED 4 ;-) Additional info: The only way to unlock the screen is to kill Xorg! This may causes loose of data, because the howl X-Sesseion is killed.

|======| | INFO | |======| # means run the command as root $ means run the command as normal user |====================================| | PROCEDURE TO RETRIEVE USEFUL INFOS | |====================================| Run # dnf debuginfo-install kscreenlocker then $ /usr/libexec/kscreenlocker_greet --testing and save all the messages you see. Do not close the previous console, open a new one and run $ pidof kscreenlocker_greet this will retrieve the PID (process id) that is an integer number. Then do $ gdb kscreenlocker_greet pid where pid is the integer you found out previously. Once GDB started, do (gdb) bt and copy all text you see.
