--- Comment #2 from Andrey <butir...@gmail.com> --- <Ctrl><Alt> + <Backspace> is handled by X11 and not Plasma, so it seems like lower-level problem indeed. That beeps might be symptom of some buffer overflow, e.g with keyboard events. XKB doesn't handle physical devices so should be indifferent. I might also be useful to look into X11 logs, I'm not sure journalctl grabs ones.. I see crashes in your log, can you also try the session with new user? What's on Wayland? Does the problem arose after some upgrade, meaning it's a regression? -- You are receiving this mail because: You are watching all bug changes.
