Ubuntu Dock appears on the display opposite to that indicated on Appearance tab

[Paul White]

* Impact

The screen labels displayed when settigns are open are inverted

* Test Case

Display 1 is the laptop's built-in monitor
Display 2 is the external monitor set as being the primary display

To reproduce:

1) Go to the Appearance tab
2) "Show on" will indicate on which display the dock is being shown
3) In my case it is set to "1. Built in display" but it appears on the second or primary display
4) Change the setting and the dock will move but...
5) In my case if I change to "2. GKE 24 (Primary display)" the dock appears on the built-in display.

* Regression potential

Checking that in settings -> display the screen labels are correct

Status changed to 'Confirmed' because the bug affects multiple users.

[Sebastien Bacher (seb128)]

Daniel, the other issue uou mentioned is different, it's the handling of what 'left' means in a RTL locale

The bug here is about the screen logic being inverted, if you pick to display the launcher on the display 1 it's shown on display 2 (same in reverse)

Hello Paul, or anyone else affected,

Accepted gnome-control-center into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gnome-control-center/1:3.36.3-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I started gnome-control-center to verify I was still seeing the bug and then enabled -proposed and updated to version 1:3.36.3-0ubuntu1.

I restarted gnome-control-center and saw the drop-down now correctly shows on which display the dock is being shown. All three settings work as they should as the dock can be moved between displays, or shown on both displays and the drop-down always shows the correct text unlike previously.

Marking as verified.
