--- Comment #25 from Thomas Lübking <thomas.luebk...@gmail.com> --- Comment #2 said "Just tried using KWin with compton as compositor and the same problem." > Is that the 'OpenGL interface' in System Settings? Yes, but while hidden when you select XRender, it's never supposed to be disabled (there's simply no code that does such) - and in your case should list GLX & EGL > Yes it was interactable. So either the screenlocker are artifacts in the framebuffer or the konsole window managed to raise above the screenlocker. => What exactly did you kill? The actual locker is ksmserver and the greeter should be restarted immedately (and no client should be exposed interim because ksmserver also holds a black barrier window. > was that Ctrl+Alt+L didn't show the kscreenlocker greeter Ie. the screen gets locked, but the greeter doesn't show up - it will likely crash. => try to invoke the greeter directly instead of locking the screen: /usr/lib/kscreenlocker_greet --testing maybe /usr/lib/libexec/kscreenlocker_greet --testing -- You are receiving this mail because: You are watching all bug changes.
