Can't view system settings with external monitor + laptop
I'm on a Lenovo x220 running 7.0 with an external monitor plugged in. I'm having a problem again which I have had in the past and I don't recall how I resolved it. With the second monitor plugged in, if I open System Settings it goes to some other monitor or desktop and I can't access it. I've tried mousing around the edges, alt-tabbing, and so on, to no avail. This has never happened with any other program, but happens often (perhaps all the time, I can't recall, but it's 100% repeatable at the moment) with System Settings. It's especially difficult since the settings I need to change are the display settings with the second monitor plugged in.
Please let me know if I need to give you any additional information in order to help you help me, and thank you as always for your time.
What if you just switch off the built-in display? You should see the taskbar and open programs. I have an HP Probook and an external display (displayport to HDMI). Trisquel works with this combination. You can add a workplace switcher applet to your taskbar.
The specs/graphics between yours and mine are similar.
Is it this you're using?

I realized that when using Gnome Shell in a dual display configuration, and letting Nautilus manage the desktop, while watching a movie full-screen on one screen and doing something with the mouse on the other screen, will minimize and hide the window on the second display. I had to disable the Gnome Shell Extension (Tweak Tool) that puts icons and the Trash bin on the desktop.
That did the trick, thanks. Worth posting this (System Settings opening in an undisplayable location with an external monitor plugged in, only visible by disabling a display) as a bug? If so, where? (Haven't done this before.) And, if not, and in any case: thanks again!
