Comment 2 for bug 1754225

Thank you for your bug report. Could you try on newer versions if that's still an issue? On 18.10 with a laptop and external monitor here there is no close buttons to pick a resolution, just a combo you select from and changing the factor doesn't reset the layout (the 2 monitors are stacked vertically and stay this way). It looks like those issues are resolved?
Also it's best to open a separate ticket for each issue you describe, it's easier to deal with this way
