Description postix 2025-07-19 11:44:07 UTC

SUMMARY

Since Plasma 6.4 kscreen no longer shows the screen's manufacturer, model or serial number as long as only a single screen is attached.

Unfortunately I also cannot find this information in KInfoCenter.

I think for debugging and purely informational purposes it would be helpful to find this information somewhere easily, e.g. as an additional label "Monitor: ..." 

Depending on the monitor's or beamer's location, it may not be easily to check on the physical device.

Dear Tracey, there are no "steps" to reproduce other than opening the Screen KCM, where the top row showing attached screens has been hidden in 6.4+ as long as only a single screen is attached.

Frameworks, Qt, etc. is not of relevance for this "wish" report.

Comment 3 postix 2025-07-23 12:25:28 UTC

Sorry, I was mistaken, this information was already hidden in 6.3 (keyword visible: kcm.multipleScreensAvailable)

In 6.3 the top row was already hidden to re-arrange screens:
* https://invent.kde.org/plasma/kscreen/-/blob/Plasma/6.3/kcm/ui/ScreenView.qml

However the combobox was still shown if I remember and read the qml part correctly.
* https://invent.kde.org/plasma/kscreen/-/blob/Plasma/6.3/kcm/ui/Panel.qml#L29

In 6.4 the code has changed a bit and it looks like it shows devices now in a Navigation Scroll View instead of a combobox:
* https://invent.kde.org/plasma/kscreen/-/blob/v6.4.3/kcm/ui/main.qml#L301

Sorry, I can't edit Bugzilla Posts.

s/However the combobox was still shown if I remember and read the qml part correctly./Same goes for the combobox

I'm also open to move this issue to Info Center. :) Probably it makes more sense there.

Passing along the feature request to the developers

I think we could keep the navigation tab bar around even with a single display — it would expose the display's name and imply how other displays would be handled later if also connected. Most tab bars don't disappear with only a single item in most of our UI.
