Daniel, Now I have experienced the 100% CPU to more times and both times I tried to follow the guide here https://wiki.ubuntu.com/Backtrace#Already_running_programs but it's not possible to go to do "If the program hangs but doesn't crash you can press ctrl+c in gdb while the program is frozen and then continue with the next step."
Then gdb hangs :-P so no luck there. See attatched gdb log file. Any suggestions what to do next? The thing I have noticed now with the 100% CPU usage is that it's always after restarting a VM several times in VirtualBox. ** Attachment added: "gdb-gnome-shell.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1800101/+attachment/5223458/+files/gdb-gnome-shell.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1800101 Title: gnome-shell uses 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1800101/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
