Bug Description

On my fresh install of Ubuntu 18 (minimal install last night) the control center will not open; it shows a loading notification on the top panel briefly, then does nothing. I have attempted to restore functionality by re-installing to no avail. The system does not recognise control center's failure to open as a bug to report.

This is the second install I've produced this bug on, the first being a fresh install on an HP xw8400 workstation, "solved" finally by switching to MATE. As I recall I was able to finagle it to appear once or twice then, but ultimately with no success - I've seen a few threads with similar problems, so something's gotta give cause this is totally ridiculous for an LTS release.

Some further information: As I'm intending to switch to MATE for preference anyway, I went ahead and installed the ubuntu-mate-desktop package and set gdm3 to default in the process (I believe it is already default for Bionic?); now on boot I see the MATE loading screen, am taken to the Gnome login screen, gnome-control-center opens. The halt-on-shutdown bug, another bug I've seen a few threads on with fresh installs, and had with my last install as well as this, was also fixed. So now I'm wondering, what has MATE changed during it's install to fix these bugs? Interesting.

Do you have the launcher placed at the bottom? we got some reports about this creating issues probably because by lack of vertical space to fit the settings dialog

I'll see about getting a backtrace when I have some time again to mess around.
No, I left the launcher on the side.
