Managed to boot back to prior kernel (I got some help). Problem is still happening.
In fact, after the icon in the launchbar stopped pulsating and disappeared the system came up syaing that an error occurred. I hope you got it, but the title was "unity-control-center crashed with signal 5 in g_settings_bind_with_mapping()" And, as an aside, the mouse wasn't clicking, but we could still use the keyboard. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1790249 Title: desktop sharing won't start after upgrading to 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1790249/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
