The first one was backlight. I don't know how significant that is but it would explain why the bug is machine-specific:
nov 07 09:14:06 perseus gnome-shell[1255]: Attempting to call back into JSAPI during the sweeping phase of GC. This is most likely caused by not destroying a Clutter actor or Gtk+ widget with ::destroy signals connected, but can also be caused by using the destroy(), dispose(), or remove() vfuncs. Because it would crash the application, it has been blocked and the JS callback not invoked. The offending signal was notify on Gjs_status_backlight_SliderItem 0x5620201502b0. == Stack trace for context 0x56201e19fe50 == #0 7ffccf769190 I resource:///org/gnome/shell/ui/status/backlight.js:57 (16688c028e70 @ 131) #1 7ffccf769ce0 b resource:///org/gnome/gjs/modules/core/overrides/GObject.js:687 (374b8fd9bec0 @ 25) #2 7ffccf769d20 I resource:///org/gnome/shell/ui/status/backlight.js:197 (16688c02c420 @ 199) #3 7ffccf769d50 I resource:///org/gnome/shell/ui/status/backlight.js:157 (16688c02c2e0 @ 12) #4 56201e26c108 i resource:///org/gnome/shell/ui/init.js:21 (374b8fd70ba0 @ 48) ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2042909 Title: Gnome shell freezing and/or taking a long time to load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2042909/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
