On a laptop, I configured KDE so that when I plug in an external monitor, it would turn off the internal monitor and turn on the external monitor instead. So I always have a single monitor active. Now, when I boot up / log in with only my internal monitor, I get the panel with all the icons/widgets in place as expected. But if I then plug in an external monitor (over mini DP), my panel is missing a few icons/widgets. Missing are e.g. the digital clock, the NM widget, the usb/external devices widget. Still there are e.g. the battery, ibus, notifications. But they're not removed from the panel - when I remove the external monitor again (and thereby switch to the internal one), they're all back as before. So my guess would be, that some icons/widgets are never told about the new display - or they look at a different variable. While writing this report, I actually tried switching back and forth a few times. Funnily, it eventually reversed - now I have the full panel on the external monitor, but not on the internal one. Might be connected to me playing with the "primary output" setting in the system settings. Reproducible: Always Steps to Reproduce: 1. Configure KDE to switch off internal monitor of laptop when an external monitor is connected (and to turn that on instead) 2. (Re-)Boot laptop with no external monitor connected 3. Log into KDE with no external monitor connected 4. Connect external monitor Actual Results: Panel missing icons/widgets Expected Results: Panel looking the same as before I did not yet investigate the behavior if I start with the external monitor connected (during boot / login already), and remove it afterwards. Running Fedora 22 on x86_64. Both displays are set to a 1920x1080 resolution. I'll try updating to 5.3.2 later on since it's now available in Fedora 22.
>Might be connected to me playing with the "primary output" setting in the system settings. Yes probably. If you have a panel on your primary monitor, when you unplug the primary monitor it will move to the new primary monitor. If you have a panel on a non-primary monitor, when you unplug that screen, the panel will get 'removed', until you plug a second screen in again. --- As for the bug it sounds like you have two panels; can you post your ~/.config/plasma-org.kde.plasma.desktop-appletsrc

Thanks
Two panels? I don't think so. I tried enabling both screens at the same time, and moving the panel I'm seeing to the right/left side (it's usually centered), but no second panel became visible. (However, KDE completely crashed after a short while the first time I tried activating both - separate bug I guess).
Okay, this whole bug report is basically bogus. The bug I'm experiencing is a different one, and based on past experiences I should have noticed so earlier. Apologies for the inconvenience! --- Actual Setting: My (only) panel is centered and set to be auto shrinking/enlarging based on its contents. As the minimum width, I defined a fairly small range and as the maximum width, the largest possible range (as wide as the screen is). Actual bug: When switching screen, the minimum width is used, instead of the actually required width (which is much lower than the maximum width). Therefore, parts of the panel content are hidden. --- Should I rename this bug or open a new one?
rename is fine.
Is it actual yet?
A lot has changed since this bug was filed. Is it still reproducible for you in Plasma 5.25? We did a lot of multimonitor improvement in that version
