** Description changed: + [ Impact ] + + Nvidia Wayland sessions sometimes flood the log with + "clutter_frame_clock_notify_presented: code should not be reached" + + This is almost harmless except that it wastes disk space and the high + frequency of messages (one per frame) impacts desktop performance. + + [ Test Plan ] + + 0. Start with either an Nvidia-only desktop providing that bug 2060268 + is NOT fixed yet; or an Nvidia desktop which also has an integrated GPU + enabled such that Nvidia is configured as the primary (boot) GPU in the + BIOS and a monitor is plugged into EACH GPU. + + 1. Log into a Wayland session. + + 2. Run: + + journalctl -f /usr/bin/gnome-shell + + and verify there is not a flood of messages with each screen redraw. + + [ Where problems could occur ] + + Wayland multi-GPU startup is the code affected here so any configuration + expecting to use multiple GPUs simultaneously in a Wayland session may + be affected. + + While bug 2060268 is unresolved even single GPU Nvidia systems will be + affected due to the phantom GPU resulting from that bug. + + [ Original description ] + Nvidia Wayland sessions sometimes flood the log with: [ 13.105877] computer gnome-shell[1264]: (../clutter/clutter/clutter-frame-clock.c:332):clutter_frame_clock_notify_presented: code should not be reached [ 13.106163] computer gnome-shell[1264]: (../clutter/clutter/clutter-frame-clock.c:332):clutter_frame_clock_notify_presented: code should not be reached [ 13.112490] computer gnome-shell[1264]: (../clutter/clutter/clutter-frame-clock.c:332):clutter_frame_clock_notify_presented: code should not be reached [ 13.125302] computer gnome-shell[1264]: (../clutter/clutter/clutter-frame-clock.c:332):clutter_frame_clock_notify_presented: code should not be reached [ 13.142242] computer gnome-shell[1264]: (../clutter/clutter/clutter-frame-clock.c:332):clutter_frame_clock_notify_presented: code should not be reached I've been seeing the issue for months although it only seems to happen *after* something has gone wrong in mutter. Not by default.
