--- Comment #1 from php4...@gmail.com --- Something somewhat similar but not quite identical happened a few minutes ago. The task manager stopped responding completely to mouse events. Unlike in the initial report, not only would it not respond to left clicks, but also right clicks and mouse-over (icons wouldn't "shine" when moving the mouse cursor over). There was also a notification baloon on the bottom right of the screen which (A) contained garbage, (B) wouldn't vanish and (C) did not have any window borders or close button. Leftovers were visible of the notification it initially contained, from Thunderbird, but it was all mangled. Applications were initially functioning properly. I could switch between them with Alt+Tab. The Shift+Super+D shortcut to minimize all windows was not working though. Then after a while things got worse. I was using Gimp (in order to edit a screenshot that I intended to attach to this report). Then I opened a tool in Gimp, one of those that open in a separate small window, and at that instant, Gimp's main window disappeared, or minimized, or went to the background, anway was no longer visible (but the small window with the tool was). Now alt+Tab no longer worked either. Additionally, when I opened a virtual terminal with Ctrl+Alt+F2, it was responding sluggishly to keyboard. At this point I had to hard-reset with the laptop's On/Off button. Until recently, I was suffering from this: https://forum.manjaro.org/t/entire-system-randomly-becomes-unstable-windows-flicker-and-sometimes-stop-responding/125241 I never reported that bug to KDE because I always assumed it belonged to something else at a much lower level (kernel, CPU drivers or something like that). I've been recently told in another thread that that is "definitely not" a kernel bug and that it is certainly in KDE. I don't know. Anyway, a reply to that thread suggested that I try adding the parameter ahci.mobile_lpm_policy=1 to my kernel configuration in Grup, and so I did. Since then, instead of the symptoms described in that report, I have started experiencing the issues described in this one. That may be a coincidence, they could be two separate unrelated issues, but it's suspicious. -- You are receiving this mail because: You are watching all bug changes.
