Every time I press "login" when my laptop wakes up from the sleep state, Gnome GUI hang up for 30 secs to 5 minutes. No keyboard shortcuts are effective and the mouse pointer can still move, but I'm unable to click.

I'm running Ubuntu 17.04 with Gnome-shell 3.24.1

Here is an error that is literally spamming my logs (I have something around 500 pages of it in less than 5 minutes). The timestamps corresponds to my problem. I used journalctl --system :

org.gnome.Shell.desktop[29510]: Window manager warning: Trying to remove non-existent keybinding "panel-menu-keyboard-accelerator".
gnome-shell[29510]: clutter_layout_manager_get_child_meta: assertion 'CLUTTER_IS_LAYOUT_MANAGER (manager)' failed

  • No, sadly, I have another problem concerning my network that I should fix before this one. askubuntu.com/questions/883375/…

    Here it says the gnome-shell extension Taskbar is the problem. Uninstall it to fix it forums.debian.net/viewtopic.php?t=124447

    Another one says it's TopIcon Plus I tried both, and the result seems to be with a combination of these plus user themes. So disabling user themes solves everything.
