I don't know if it's related or not to the problem, but here it goes. I'm using Ubuntu 17.10 on a laptop that has a Nvidia 540M GPU and also an onboard Intel GPU. It seems Ubuntu is assigning a monitor for each (there's an unknown second monitor on my setup and I have no idea where it came from).
In the end, my solution was disabling that unknown monitor. That made the "virtual screen" I was referring to before disappear and the system settings app to work again. But, oddly, it only began malfunctioning after I moved the dock to the bottom position. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1721637 Title: can't open system settings(Ubuntu 17.10), icon is visible but settings don't dislay To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1721637/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
