perfect, i can confirm now it's a different error-path for me, trying to
create a new bugreport, but launchpad giving me 504's (timouts) all the
time, waiting till it functioning again.
AI slop tl;dr;
Reproduced today (27min after boot, notifications re-enabled). GDB backtrace of
frozen gnome-shell shows:
Thread 1 "gnome-shell" — main thread stuck in:
pthread_cond_wait
→ libEGL_nvidia.so.0 (frames #7-#14, no symbols)
→ cogl_onscreen_egl_swap_buffers_with_damage (cogl-onscreen-egl.c:290)
→ meta_onscreen_native_swap_buffers_with_damage
(meta-onscreen-native.c:1819)
→ clutter_frame_clock_dispatch
NVIDIA EGL driver deadlocks inside eglSwapBuffers on an internal
condition variable. GPU is fine (nvidia-smi responds, P8/44C/0%), no
kernel errors. D-Bus daemon alive but gnome-shell unresponsive.
Trigger: Notifications — they cause frequent small damage rects via
eglSetDamageRegion. 26h stable without notifications, freezes within
minutes with them. Likely related to mutter#4658 / MR !5007 (still
draft).
Crash dump via killall -ABRT attached once Launchpad is back up. Full
GDB backtrace (thread apply all bt full) available.
NVIDIA 595.58.03, Kernel 7.0.0-12, RTX 3060 Ti, dual 4K displays.
