--- Comment #2 from Simon B <sbutcher+b...@gmail.com> --- Another observation. This only seems to occur with 2 external monitors. With one external monitor and the laptop screen off, removing the usb C cable to the dock while the laptop is sleeping, results in a working lock-screen on resume. With 2 external monitors and the laptop screen off, the problem occurs. The only way to recover is ctrl-alt-f2 and kill kscreenlocker_greet process, then returning to ctrl-alt-f1 shows the lock screen as usual. -- You are receiving this mail because: You are watching all bug changes.
