Maybe it's an old problem but I did a fresh install of 18.04.1 yesterday and today I moved the Dock to the bottom and could not get access to Settings any more.
None of the above helped me at all but the solution is here https://askubuntu.com/questions/366813/disable-second-non-existent- screen-from-command-line. At this link the top command did nothing - but starting from First run: those two commands did the trick, in my case for the second command I had to type "VGA-1-2" instead of VGA2. Have yet to reboot so I will find out if I have to add it to the "run on start" Cannot believe this bug has not been fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1721637 Title: can't open system settings(Ubuntu 17.10), icon is visible but settings don't display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1721637/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
