--- Comment #5 from yP6pxFJmSpO2xZwPW <fuxfwgc4a2i...@gmail.com> --- After some investigations i found i hope temporary workaround to attempt to return control to desktop. 1) Wake up computer and see black screen with mouse pointer 2) make Ctrl+Alt+F3 and return back to X11 until plasmashell crash (sometimes 3 - 20 quick switching needed) 3) It will be visible desktop and popup reporting plasmashell crashed and restarted but desktop still very slow . In this case need to open plasma shell console and to do extra : kquitapp5 plasmashell kstart5 plasmashell After it system again operates normal. -- You are receiving this mail because: You are watching all bug changes.
