Not mirrored

When I plug in my external screen, the desktop gets extended. However the notification widget sees it as mirrored, and therefore inappropriately enters Do No Disturb mode.

I can turn Disturb mode off, but it turns on again every time I disconnect and re-connect the external display.

Please provide the output of kscreen-doctor -j with screens in this configuration.

Attached.
Comment 4 Kai Uwe Broulik 2020-02-27 08:18:14 UTC 
So your right screen is at
"pos": {
                "x": 1919,
                "y": 0
            },
which overlaps by 1 pixel. How did you set the screen position? Through the OSD or by manually dragging?

I probably should make the check more lenient (e.g. only if the screens overlap by 10 pixels or so) but I would like to know the cause first
Comment 5 Nate Graham 2020-02-27 15:46:27 UTC 
I didn't manually set anything; I just plugged it in and it automatically appeared to the right of my current screen.

Could the check see if the geometry of both screens is 100% overlapping, rather than having any overlapping?
Comment 6 Kai Uwe Broulik 2020-02-27 15:48:04 UTC 
You sure it didn't restore a previous config of sorts? Then it's probably a KScreen bug.

100% wouldn't work as you can have different sized screens overlapping, e.g. a projector only showing a section of your main screen.
Comment 7 Nate Graham 2020-02-27 17:56:52 UTC 
How can I check to see if it restored a previous config?

Regardless, yeah I guess it would be nice to build in a bit of wiggle room for the overlap calculation.
Comment 8 Jose M. Prieto 2020-08-31 13:52:39 UTC 
I'm also seeing this and had a 1px overlap. I noticed the DnD mode after I disabled one of the screens in kscreen for a screen sharing session and then enabled it again. 

I have tried to reproduce:

 * if I disable the screen, apply, enable screen and apply I don't get the 1px overlap, but
 * if I close kscreen after disabling, when I open it again and enable the screen, the 1px overlap is there.

I also have the 1px overlap. But
 >  disable the screen, apply, enable screen and apply
did not help :/

Is there already a bug for kscreen filed?
Comment 10 Nate Graham 2021-10-24 14:21:44 UTC 
Indeed: Bug 432873. Marking as a duplicate.
