--- Comment #8 from Shmerl <shtetl...@gmail.com> --- OK, it happened again, and I can tell it was a reset, since I see it in dmesg (see below). The session got corrupted again, but was reacting on some garbled fashion to input like before. I switched to tty, and run kwin_x11 --replace The result was: kwin_x11: FATAL ERROR while trying to open display. I probably should have set DISPLAY variable? And after set session was interrupted and fell out into sddm login. ----------------------- [16346.087369] [drm:gfx_v10_0_hw_fini [amdgpu]] *ERROR* KGQ disable failed [16346.353602] [drm:gfx_v10_0_hw_fini [amdgpu]] *ERROR* KCQ disable failed [16346.614280] [drm:gfx_v10_0_cp_gfx_enable [amdgpu]] *ERROR* failed to halt cp gfx [16346.679190] pcieport 0000:00:03.2: PME: Spurious native interrupt!
